Technical Field

The present application relates to the field of integrated circuit design technologies, and in particular, to a method and apparatus for generating a power supply design command, an electronic device, and a storage medium.

Background

Chips (chips) are small in size and are widely used in computers and other electronic devices. A chip is a silicon wafer containing integrated circuits (Integrated Circuit, ICs) that integrate together a number of commonly used electronic components (such as resistors, capacitors, transistors, etc.) and the wiring between them through semiconductor processes to form a circuit with specific functions.

To achieve the design of an integrated circuit, designers typically implement the design of an integrated circuit with the aid of computer aided design (CAD-Computer Aided Design, CAD) software and electronic design automation (Electronic Design Automation, EDA) systems. In the design process of the integrated circuit, the architecture design related to the power supply in the integrated circuit can be realized through a power supply design command.

In the related art, in some cases, the power supply design unit and the connection of different connection lines can be manually instantiated in the design, however, for large-scale design, the manual efficiency is extremely low, the workload is huge, and the error is extremely easy due to the fact that the signal lines are extremely large and the power consumption strategy is complex; in other cases, power supply design commands may be manually written by a chip architect or design engineer to describe the power supply design intent in a circuit by automated commands, which, while improving efficiency over the former, requires additional time and learning costs for the designer to master the grammar rules for generating the source design commands, is error-prone and time-consuming, and is still not satisfactory in design efficiency.

Detailed Description

In order to make the technical solution of the present application better understood by those skilled in the art, the technical solution of the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the application described herein may be implemented in sequences other than those illustrated or otherwise described herein. The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.

Here, "at least one of the items" appearing in the present application means three cases in parallel including "any one of the items", "a combination of any of the items", "an entirety of the items". For example, "including at least one of a and B" includes three cases in parallel: (1) comprises A; (2) comprising B; (3) includes A and B.

As previously mentioned, during the design of integrated circuits, manual design and manual programming of commands can result in power supply designs that are prone to error and design inefficiencies.

For example, in the design process of an integrated circuit, a designer may create a high-level behavioral description of the integrated circuit device using, for example, a hardware description language (Hardware Description Language, HDL), which may include, by way of example, verilog HDL and VHDL. Taking EDA systems as an example, EDA systems may generally receive HDL data of an integrated circuit device and convert the HDL data to netlists at various levels of abstraction.

For hardware description languages such as HDL, a manual design method is adopted, and low-Power-consumption units such as a Level Shifter (Level Shifter), a Power Switch (Power Switch), an Isolation unit (Isolation Cell), a retention register (Retention Register) and the like and Power lines (Power Supply Line) for connecting different devices are instantiated in the design by using the HDL language. However, in large scale designs, due to the extremely large number of devices and signal lines and the complex power consumption strategies, manual efficiency is extremely low, workload is enormous, and errors are extremely prone.

In this regard, in the related art, for example, low Power design and verification of a chip can be conveniently performed by introducing a unified Power format (Unified Power Format, UPF) file, a Power design definition, which cannot be described by the above hardware description language, is provided, and a low Power design Intent (Power intelt) of a user can be described using some standard sentence.

Specifically, an architect or design engineer of the chip can manually write power supply design commands such as UPF files, greatly improving power supply design efficiency. Here, the UPF file may refer to a Power consumption management file written in accordance with the IEEE low Power, energy aware electronic system design and verification standard (IEEE Standard for Design and Verification of Low-Power, energy Aware Electronic System), and the file extension may be ". UPF". The UPF file may describe a low power consumption intent in the chip design, which is a language standard specifically used to describe circuit power consumption intent.

Under the coordination and support of UPF files, integrated circuit designers can simultaneously verify the low-power management strategy related to power state control on RTL (Register Transfer Level, register transmission level) code files and UPF files in the verification stage of hardware description language so as to discover power management problems in time in early design, and play roles of ensuring the accuracy of design, shortening development period and reducing design iteration.

However, in the related power supply design method, in the power supply design file generation process such as the UPF file, a chip architect or a design engineer is required to manually write the design command, and although the command generation can be realized, it takes extra time and learning cost to grasp the grammar rules of the design language such as the UPF, which is error-prone and time-consuming. In addition, there are multiple versions of design criteria such as UPF, which require a lot of time to study, complex writing process, require more, are prone to error, and require a lot of time for continuous debugging.

In addition, as the functions of the chip become more complex and the computation power becomes stronger, the requirements on the manufacturing process of the chip become more advanced, the atomic level is more and more towards, the integration level is higher and higher, the single chip with the transistors up to one hundred watts can be produced in mass, the power consumption also often reaches the hundred watts level, the application of the power supply design technology is more and more common, and the requirements on low power consumption are higher and higher.

In this case, the conventional manual code writing method is heavy in workload, long in time consumption, prone to error, long in iteration period, and low-power consumption is usually defined by architects/design engineers of the chip, but most architects/design engineers may not understand the design rule of the power supply well, so that learning cost is high, and time of the chip facing the market is increased.

In view of the above, exemplary embodiments of the present application provide a power supply design command generation method, a power supply design command generation apparatus, an electronic device, and a computer-readable storage medium, which can solve or at least alleviate the above-described problems.

In a first aspect of the exemplary embodiment of the present application, a power supply design command generation method is provided, and will be described below with reference to fig. 1 to 11.

The power supply design command generating method according to the exemplary embodiment of the present application may be applied to a power supply design scenario of integrated circuit electronic design automation software, for example, a user terminal may be loaded with integrated circuit electronic design automation software, a user may input a power supply architecture diagram, and the power supply architecture diagram may include at least one target unit diagram selected from a preset diagram library and configuration information for configuring each target unit diagram, where the preset diagram library includes at least one unit diagram, and each unit diagram corresponds to one power supply design unit.

The integrated circuit electronic design automation software can receive the power architecture diagram input by a user, can analyze each target unit diagram in the power architecture diagram and corresponding configuration information, determine unit design commands corresponding to each target unit diagram in the power architecture diagram, and can generate the power design commands based on the unit design commands of each target unit diagram in the power architecture diagram.

According to the power supply design command generation method of the exemplary embodiment of the application, the target unit graph and the configuration information in the power supply structure graph are analyzed by receiving the power supply structure graph input by a user, the unit design command corresponding to each target unit graph is determined, and then the power supply design command can be generated, so that manual specific design is not required, on the premise that the power supply design of the circuit is described through the automatic power supply design command, the intelligent and automatic conversion from the intuitive and easy-to-understand power supply structure graph to the final power supply design command can be realized, and the power supply design command can be obtained quickly and efficiently even if a designer does not know the professional grammar rules.

The above user terminal may be, for example, a tablet computer, a notebook computer, a digital assistant, a wearable device, etc., however, the implementation scenario of the above power design command generation method is only an example scenario, and the power design command generation method according to the exemplary embodiment of the present application may also be applied to other application scenarios, for example, it may also be that a user generates a power design command to a server through a network at a user terminal (for example, a mobile phone, a desktop computer, a tablet computer, etc.), and a power architecture diagram input by the user may be sent to the server, where the server may perform the power design command generation by executing the power design command generation method according to the exemplary embodiment of the present application, and may be a stand-alone server, a server cluster, or a cloud computing platform or a virtualization center.

It should be noted that, although the embodiment of the present application is described taking the generation of the power design command as a command in the UPF file as an example, the embodiment of the present application is not limited to be applied to the UPF file, but may be applied to other power design command files in the power electronic design of an integrated circuit.

Specific steps of a power supply design command generation method according to an exemplary embodiment of the present application will be described below with reference to fig. 1. The power supply design command generation method may be applied to integrated circuit electronic design automation (Electronics Design Automation, EDA) software, which may be run as a stand-alone application, may be formed as an existing design software or as a plug-in to drawing software, where the integrated circuit electronic design automation software may be, for example, but not limited to, protel, orCAD, enFortius, etc., or may be drawing software that can be used to directly draw a power supply architecture diagram, such as UPF drawing software, autoCAD, microsoft vision, excel, etc.

As shown in fig. 1, the power supply design command generation method may include the steps of:

in step S110, a power architecture diagram input by a user may be received.

Here, the power supply architecture diagram may include at least one target unit pattern selected from a preset pattern library, which may include at least one unit pattern, each of which may correspond to a power supply design unit, and configuration information configuring each target unit pattern.

For example, the power architecture diagram may be a power design architecture diagram for power consuming elements in an integrated circuit design, which may include one or more power design elements. The power architecture diagram may represent a supply network architecture (supply network) of a power supply of a low-power chip design, and the drawing of the power architecture diagram may refer to a related industry standard, for example, an industry standard IEEE Std 1081.

Here, the power supply design unit may be, for example, but not limited to, a power domain, a power port, a power line, a ground line, a level shifter, a power switch, an isolator, and the like. The power supply design unit, also called a unified low power consumption unit (power architecture), may specifically refer to related industry standards (such as IEEE Std 1081), including: power_ domain, supply _port, supply_net, power_switch, level_ shifter, isolation.

According to an embodiment of the present application, a preset graphic library may be generated in advance, which may include unit patterns corresponding to various power design units that may be used for power architecture design, each unit pattern representing one power design unit, and the unit patterns corresponding to the power design units may be unique, and the unit patterns corresponding to different power design units may be different.

The user can select the unit patterns from the preset pattern library according to the design requirement and configure the unit patterns, so that the design of the power supply structure patterns is completed.

Here, the "receiving the power architecture diagram of the user input" may refer to receiving an input action of the user by selecting and configuring the unit diagram from a preset graphic library to generate the power architecture diagram, for example, the power architecture diagram in the current editing interface may be received in response to an editing operation of the user (e.g., editing the current unit diagram or introducing a new unit diagram) or at predetermined time intervals during the user editing the current power architecture. In addition, the "power architecture diagram for receiving user input" may also refer to an existing power architecture diagram for receiving user input, for example, a power architecture diagram designed in advance based on a preset graphic library, or a power architecture diagram designed by other design software.

Further, the "power architecture diagram" received here may be a power architecture diagram including a complete design, or may be a power architecture diagram of a non-complete design, for example, a power architecture in which only a part of the power architecture is designed.

As an example, the configuration information configuring each target unit graphic may include at least one of a location, a name, a connection relationship, and an internal design of the target unit graphic. The configuration information of the target unit pattern may be used to characterize the attribute of the target power supply design unit corresponding to the target unit pattern, for example, the name, connection relationship, power set, power supply domain, operation mode, control unit, control signal, control mode, etc. of the target power supply design unit, which will be described in detail below.

The above describes a process in which the user can select a target unit pattern based on the unit patterns in the preset pattern library to construct a power architecture pattern, and an example of generating the preset pattern library will be described below.

For example, as shown in FIG. 2, the preset graphic library may be generated by:

in step S210, a unique corresponding unit pattern may be designated for each power supply design unit to be added to the preset pattern library.

In this step, one or more power supply design units to be added to the preset graphic library may be determined according to actual needs or according to common devices in the power supply design field, and a unique corresponding unit graphic may be designated for each power supply design unit, where the form of the unit graphic may be arbitrary as long as the unit graphic of different power supply design units is different. The user can add the cell pattern corresponding to the power supply design cell to be added to the design interface for editing and designing when designing the power supply architecture.

As an example, fig. 3 gives some corresponding examples of power supply design units and unit patterns, as shown in fig. 3, a power domain (power_domain) may be represented by a rectangle, a power line or a ground line (where the power line and the ground line may be distinguished by solid lines of different colors) (supply_net), a power port (supply_port) may be represented by a solid block, a power switch (power_switch) may be represented by a circle having an "x" inside, a level shifter (level_shift) may be represented by a triangle, an isolator (isolation) may be represented by a semi-ellipse, etc., however fig. 3 is merely an example, and the unit patterns may have other forms.

Here, the preset graphic library may be a custom graphic library, and the format of the unit graphic may be SVG, PNG or other image formats, but it is not limited to the image format, for example, xml, etc. Each unit graphic may have, for example, a unique identifier.

Fig. 4 illustrates an example of a preset graphic library and a power design interface, and as shown in the left part of fig. 4, various unit graphics may be included in the preset graphic library, and each unit graphic may be marked with its corresponding power design unit, for example, may be marked under the unit graphic. The user can add the unit graphic representing the power supply design unit to be added to the power supply design interface (as shown in the right part of fig. 4) by way of dragging or inserting as needed.

In the process that a user draws a power supply structure graph by using the unit graphs in the preset graph library, when the user selects a certain unit graph, the type of the power supply design unit corresponding to the unit graph can be determined by analyzing the selected unit graph and extracting the unique identifier or identifying the unit graph.

As an example, a predefined mapping table may be pre-stored, which may map the unique identifier of the unit pattern or the unit pattern itself to the category of the corresponding power supply design unit, e.g. the mapping table may have a correspondence as shown in fig. 3 above.

In an actual design, a user (e.g., a chip designer) may select a graphic corresponding to a low power consumption unit desired to be added from a preset graphic library, where a corresponding graphic block may be selected according to the low power consumption unit desired to be added, for example: when it is desired to add a power domain, then a graphic representing the power domain, a rectangle, is selected.

In step S220, a graphic parsing rule corresponding to each unit graphic may be determined.

Here, the graphic parsing rule may characterize correspondence between configuration information of the unit graphic and unit attributes of the corresponding power supply design unit.

As described above, the configuration information may include, for example, but not limited to, at least one of a location, a name, a connection relationship, and an internal design of the target unit graphic. The unit attributes may include, for example, but not limited to, at least one of a name, connection relationship, power set, power domain, mode of operation, control unit, control signal, and mode of control of the power design unit.

The graphic parsing rules may be used for converting from graphic language to unit design, and different configurations of the graphics may correspond to different attributes of the actual power supply design unit, and when the same unit graphic is configured differently, the corresponding power supply design unit may perform different functions or play different roles.

Specifically, the user may implement the power supply design by configuring each unit graphic (e.g., changing the position or style of the unit graphic, etc.) in the power supply design interface. Here, the configuration of the cell pattern may be mapped to the configuration of the attribute of the corresponding power supply design cell. For example, taking the cell pattern shown in fig. 3 as an example, the position, the affiliation, the name, etc. of the power domain may be configured by configuring the position, the affiliation, the name, etc. of the rectangle; the positions, connection relationships, connection manners, names, and the like of the power supply line or the ground line, the power switch, the level shifter, and the isolator may be respectively configured by configuring the positions, connection relationships, connection manners, names, and the like of the solid line, the circle, the triangle, and the semi-ellipse having an "x" inside.

In this step S220, the configuration information of the user on the unit graphic, such as parsing the data source, the color scheme, the connection relationship, etc., as auxiliary information may be parsed according to the graphic parsing rule to determine the specific attribute setting of the user on the corresponding power supply design unit.

Further, the user may name each of the unit graphs added to the design interface to distinguish between different kinds of unit graphs or to distinguish between a plurality of unit graphs of the same kind, for example, as shown in fig. 4, a plurality of unit graphs each representing a power domain may be named as "PD1", "PD2", and "PD3", respectively, but it is not limited thereto, and according to an embodiment of the present application, the unit graphs may be automatically named without the user naming the added unit graphs, and a naming rule thereof may be, for example, in the form of a combination of "kind of unit graph" and "number", for example, a unit graph representing a power domain may be named as "pd_n", wherein n may represent a rectangle added to the interface by n.

In step S230, a preset graphic library may be generated based on the unit graphic and the graphic parsing rule corresponding to the unit graphic.

In this step, a preset graphic library may be generated for the user to design the power architecture based on the unit graphic and a graphic parsing rule indicating a correspondence between the unit graphic and the power design unit.

Through the mode of presetting the graphic library, even if the command of the power supply design language is unfamiliar or unsophisticated, a chip architect/front-end designer can perform rapid and accurate low-power-consumption power supply design according to the graphic power supply design unit, so that the power supply design command can be automatically generated in the subsequent steps, the design process is simplified, and the design work efficiency and universality of the method are improved.

Referring back to fig. 1, in step S120, each target unit pattern in the power architecture diagram and corresponding configuration information may be parsed to determine a unit design command corresponding to each target unit pattern in the power architecture diagram.

The unit design command may also be referred to herein as a power intent command (power intent commands) and may refer to a related industry standard (e.g., industry standard IEEE Std 1081). The cell design commands may include, for example, but are not limited to: a command "create_power_domain" for generating a power domain, a command "create_supply_port" for generating a power port, a command "create_supply_net" for generating a power line or a ground line (which may also be referred to as a power line network), a command "create_supply_set" for generating a power set, a command "create_logic_port" for generating a logical port, a command "create_logic_net" for generating a logical line, a command "connect_supply_net" for generating a connecting logical line, a command "connect_logic_net" for generating a connecting logical line, a command "create_power_switch" for generating a level shifter, a command "set_shift" for generating an isolator, and the like.

As an example, as shown in fig. 5, for each target cell pattern in the power architecture diagram, the cell design command may be determined by:

in step S510, a target power supply design unit corresponding to the target unit pattern may be determined.

In the case where a target unit pattern is added to the design interface, the target power supply design unit to which it corresponds may be determined by a unique identifier of the target unit pattern or identifying the target unit pattern itself.

In step S520, the configuration information of the target unit graphic may be parsed to obtain attribute information corresponding to the unit attribute of the target power supply design unit.

After the user configures the target unit graphic or after the user stops editing the target unit graphic, the configuration information of the target unit graphic can be analyzed according to the graphic analysis rule to determine the attribute of the target power supply design unit.

As an example, the attribute information may include, but is not limited to, at least one of a name of the target power supply design unit, a connection relationship, a power supply set, a power supply domain, a work manner, a control unit, a control signal, and a control manner. This will be described in detail below with respect to specific unit patterns.

In step S530, a cell design command may be generated based on the attribute information.

In the case of determining a target power supply design unit corresponding to a target unit pattern and attribute information thereof, a unit design command may be generated for the target unit pattern.

In this way, it is possible to determine the user's design intention to the actual target power supply design unit by parsing the target unit graphic and the configuration information thereof, and automatically convert such intention into the unit design command, which enables the determination of the design command corresponding to each target unit graphic without the user directly inputting the unit design command. Several examples of the determination unit design command will be specifically described below.

In addition, by respectively generating the unit design command for each target unit graph to generate a complete power supply design command, the method is beneficial to modularized design commands, can facilitate searching or editing of the design commands of the local units, can call out the corresponding unit design commands by checking or clicking the target unit graph, so as to check or modify the local commands, and improves the working efficiency of subsequent testing, maintenance and other works.

In addition, in this step S120, the following steps may be further included: the target unit graphics belonging to the same category can be extracted according to the category of the unit graphics in the preset graphics library; the unit design commands of the target unit graphs under each category can be respectively determined by analyzing according to the categories of the target unit graphs.

Specifically, when analyzing each target unit graph and corresponding configuration information in the power architecture graph, the target unit graph can be extracted from each category according to the category, and the target unit graph under the same category is analyzed to obtain the unit design command.

In this way, when generating the final power supply design command, it is allowed that the unit design commands of the target unit graphics belonging to the same category may be written together, thereby facilitating subsequent viewing or processing of the commands by category.

In step S130, a power supply design command may be generated based on the cell design command of each target cell pattern in the power supply architecture diagram.

In this step, in an example, in a case where only a unit design command of one target unit pattern is determined (for example, only one target unit pattern is included in the power architecture pattern, or when a single target unit pattern is recognized in real time), the unit design command of the target unit pattern may be directly taken as a final power design command; in another example, in the case where a unit design command for a plurality of target unit patterns is determined, the unit design commands for the target unit patterns may be combined or fused together to obtain a power supply design command.

As an example, the generated power design command may be stored in a unified power consumption format (Unified Power Format, UPF) file, but is not limited thereto and may be stored as a file of another format.

According to the power supply design generating method of the exemplary embodiment of the present application, the power supply design unit may be described using a graphical method, and the unit design command may be automatically generated to generate the power supply design command. Therefore, through a graphical mode, the power supply design can be more intuitively performed, so that chip practitioners can more easily understand the power supply design without mastering rules of excessive power supply design standards, uncontrollable risks caused by human reasons can be avoided, the flow of the low-power-consumption power supply design is greatly shortened, and the time for updating and iterating commands for one time is basically insensitive to design.

In addition, compared with the traditional power supply architecture diagram generated by using codes, the method for generating the power supply design has the advantages that design commands such as RTL codes or UPF codes are provided firstly in the traditional technology, and the power supply architecture diagram is generated, and chip research personnel can directly draw the sketch of the chip architecture to start design, further, in combination with the follow-up steps, the power supply design commands are automatically generated in the drawing process, the threshold of generating the power consumption architecture diagram of the chip by using code programming by research personnel is reduced, and the chip design efficiency is improved by quickly and automatically generating the power supply design commands.

Having described the general idea of determining a cell design command in the power supply design command generation method according to an embodiment of the present application in step S530 above, several examples of determining a cell design command will be given below.

In an example where the power supply design unit includes a power supply line, the target unit pattern may include a first pattern corresponding to the power supply line, for example, as shown in solid lines in fig. 4, and the unit design command corresponding to the first pattern may include the first unit design command.

Here, the power line may also be referred to as a power line net (supply_net), which may be divided in a circuit connection manner, not entirely according to the layout of the physical cable. For example, in the example of fig. 4, the first solid line 1 drawn from the power supply port VDD0V8 may be regarded as one power supply line (or power supply line net); since the inputs of the second solid line 2 and the third solid line 3 drawn from the power supply port VDD0V6 are the same power supply port VDD0V6, the second solid line 2 and the third solid line 3 can also be regarded as one power supply line (or a power supply line network).

In this example, as shown in fig. 6, the cell design command corresponding to the target cell pattern may be determined by:

In step S610, in response to acquiring the first character information overlapped with the first graphic from the configuration information of the first graphic, the first character information may be determined as the name of the power line.

Specifically, the user may configure the first graphic when adding the first graphic, and for example, may input first character information as the name of the power line. In the process of analyzing the configuration information of the first graph, the first character information on the first graph can be collected, and if the first character information is collected, the name of the power line can be determined.

In step S620, in response to not acquiring the first character information from the configuration information of the first graphic, the following steps may be performed: identifying an associated graph connected to the first graph and acquiring the name of the associated graph; the name of the power line is determined based on the name of the associated graphic.

As an example, the association pattern may be connected to an end of the first pattern, for example, as illustrated in fig. 4, and for the first pattern formed by the first solid line 1, the association pattern may include a cell pattern corresponding to the power supply port VDD0V 8; for the first pattern formed by the second solid line 2 and the third solid line 3, the associated pattern may include a cell pattern corresponding to the power supply port VDD0V6 and a cell pattern corresponding to the power supply switch SW; as for the first pattern formed by the fourth solid line 4, the associated pattern may include a cell pattern corresponding to the power switch SW and a cell pattern corresponding to the power domain PD 3.

Specifically, if the first character information is not acquired in the configuration information of the first graphic, it may be considered that the user does not name the first graphic when adding the first graphic, that is, does not input the corresponding name. In this case, the name (net_name) of the power line corresponding to the first graphic may be automatically generated based on the name of the associated graphic connected to the first graphic.

In the case where the power supply design unit further includes a power supply port, the association pattern may be a unit pattern corresponding to the power supply port. In this case, the name of the power line may be determined based on the name of the association graph by: responding to the power supply design unit corresponding to the associated graph as a power supply port design unit, and taking the name of the associated graph as the name of the power supply line; and determining the name of the power line based on the name of the associated graphic and the name of the power port to which the associated graphic is connected, in response to the power supply design unit corresponding to the associated graphic being a non-power port design unit.

Specifically, when the associated graphic includes a unit graphic corresponding to the power port, the name of the power line may be determined based only on the name of the power port; when the associated graphic does not include the unit graphic corresponding to the power port, the name of the power line may be determined based on the name of the power port connected to the associated graphic, for example, the name of the power port connected to the associated graphic may be taken as a name body of the power line, and the name of the non-power port design unit corresponding to the associated graphic may be taken as a suffix of the power line, to determine the name of the power line.

Here, it is preferable to consider that the names of the power supply lines are determined by the names of the power supply ports, and even in the case where the power supply design unit to which the power supply lines are connected is a non-power supply port design unit, the power supply lines may be named in consideration of the names of the power supply ports associated with the non-power supply port design unit, and thus, the electrical connection relationship of the power supply lines may be more easily reflected by the names of the power supply lines, which contributes to the understanding of the connection relationship of the power supply lines by the user.

Still taking fig. 4 as an example, for the first graph formed by the first solid line 1, the power supply line may be named based on the power supply port VDD0V8 connected to the end thereof, for example, "VDD0V8"; for the first pattern formed by the second solid line 2 and the third solid line 3, the power supply line may be named based on the power supply port VDD0V6 connected to the end thereof, for example, "VDD0V6"; for the first pattern formed by the fourth solid line 4, the power supply line may be named, for example, "VDD0v6_sw" based on the power supply switch SW connected to the end of the fourth solid line 4 and the power supply port VDD0V6 connected to the power supply switch SW.

In step S630, a first cell design command is determined based on the name of the power line.

In the case where the name of the power line is determined based on the above-described step S610 and step S620, the first cell design command may be determined based on the name of the power line, and for example, the command "create_supply_net" may be generated.

The following illustrates example code for a first cell design command generated by way of example of the power architecture diagram in fig. 4:

“create_supply_net VDD0V8

create_supply_net VDD0V6

create_supply_net VDD0V6_SW”。

the method for determining the first unit design command of the power line can allow the identification of the name of the power line input by the user, and can also automatically name the power line when the user does not name the power line, so that the automatic generation of the first unit design command is realized.

In addition, in the case where the power supply design unit includes the ground line, the method of generating the unit design command corresponding to the ground line is the same as that of the above-described power supply line, and thus, a description thereof will not be repeated here. Taking fig. 4 as an example, an example code of a cell design command corresponding to a ground line may be: "create_supply_net VSS".

Furthermore, according to an exemplary embodiment of the present application, the cell design command corresponding to the first graphic may further include a second cell design command, which may characterize a connection relationship of the power line and the power port.

In this example, the cell design command corresponding to the target cell graphic may also be determined by: in response to identifying that the first graphic is connected to a graphic corresponding to the power port, a second cell design command is generated based on the name of the power line and the name of the power port.

Specifically, in the case where the name of the power supply line and the name of the power supply port are determined, the second unit design command may be generated based on the association relationship of the power supply line and the power supply port connected to each other, and for example, the command "connect_supply_net" may be generated. Here, a process of determining the name of the power port will be described in detail below.

For example, taking the grammar rules of the UPF as an example, the command "connect_supply_net" may be expressed as "connect_supply_net input power line name—port name to which ports input power line is connected. Taking the power architecture diagram in fig. 4 as an example, an example code of the generated second unit design command may be as follows:

“connect_supply_net VDD0V8 -ports VDD0V8

connect_supply_net VDD0V6 -ports VDD0V6”。

by the method, the second unit design command representing the corresponding relation between the name of the power line and the name of the power port can be generated based on the name of the power line and the name of the power port, so that the design command of the connection relation in the power architecture diagram can be automatically generated.

In addition, in the case where the power supply design unit includes the ground line, the method of generating the unit design command corresponding to the connection relationship between the ground line and the power supply port (i.e., the ground port) is the same as that of the power supply line, and thus, a description thereof will not be repeated here. Taking fig. 4 as an example, an example code of a unit design command corresponding to a connection relationship between a ground line and a power port may be: "connect_supply_net VSS-ports VSS".

Further, according to an exemplary embodiment of the present application, the power supply design unit may further include a ground line, such as a fifth solid line 5, a sixth solid line 6, and a seventh solid line 7 shown in fig. 4, and the target cell pattern may further include a second pattern corresponding to the ground line, which may have a different pattern, such as a different color, a different line type, a different thickness of the line, etc., from the first pattern of the power supply line, such as a solid line having a different color from the first pattern.

Each power line may be configured with a corresponding ground line to form a power set (supply set), and thus, information of the power set may be obtained by analyzing configuration information of cell patterns of the power line and the ground line.

In this case, the cell design command corresponding to the first graphic may further include a third cell design command, where the third cell design command may characterize a power supply set of each power supply line, which may be written as a command "create_supply_set", for example. In this example, the cell design command corresponding to the target cell graphic may also be determined by:

In one case, in response to identifying at least one first pattern and a plurality of second patterns in the power architecture pattern, the following steps may be performed: acquiring first configuration information of each first graph and/or second configuration information of each second graph; a third cell design command corresponding to each of the first graphics is determined based on the first configuration information and/or the second configuration information.

Here, the first configuration information may include power set information of a power port to which the first graphic is connected, and/or the second configuration information may include power set information of a power port to which the second graphic is connected.

Specifically, in the case where there are a plurality of second patterns, it is described that there are a plurality of ground lines, in which case it is necessary to determine which of the plurality of ground lines is the ground line paired with each first pattern. In general, pairing information (or information of a power supply set) of a power supply line and a ground line may be stored in either or both of attribute information of the power supply line and the ground line paired with each other, for example, an identifier "power" may be added to the "function" attribute to specify the power supply line, a ground line identifier "ground" may be added to the "function" attribute to specify the ground line, and the names of the ground lines may be GND, VSS, or the like, for example. Therefore, the first configuration information of each first graph and/or the second configuration information of each second graph can be analyzed to determine specific pairing conditions.

In the case where at least one first pattern and a plurality of second patterns are identified in the power architecture pattern, a third cell design command may be determined for each first pattern by:

in response to identifying that the first graphic is connected to a graphic corresponding to the power port, a third cell design command may be determined based on the first configuration information and/or the second configuration information of the first graphic.

Specifically, in the case where a power line or a ground line is connected to the power port, for example, the power lines VDD0V8, VDD0V6 and ground line VSS of fig. 4, the power set information may be determined by directly parsing the corresponding configuration information to generate the third cell design command.

For example, assuming that power supply lines VDD0V8 and VDD0V6 and ground lines VSS1 and VSS2 are present in the power supply structure pattern, information such as "VDD0V8 paired with VSS 1" and "VDD0V6 paired with VSS 2" may be stored in configuration information of the cell pattern of the power supply line and/or the ground line. In this case, by acquiring and analyzing the configuration information, a third cell design command corresponding to the power supply lines VDD0V8, VDD0V6, respectively, may be generated, an example code of which may be as follows:

“create_supply_set SS_VDD0V8-function {power VDD0V8} -function {ground VSS1}

create_supply_set SS_VDD0V6-function {power VDD0V6} -function {ground VSS2}”。

in response to identifying that a first graphic is connected to a non-power port graphic corresponding to a non-power port design unit, a third unit design command may be determined based on first configuration information and/or second configuration information of another first graphic to which the non-power port graphic is connected. Here, the other first graphic may be connected to a graphic corresponding to the power port.

Specifically, in the case where a power line or a ground line is connected to a non-power port, for example, the power line VDD0v6_sw of fig. 4, the power line or the ground line may inherit power set information of the power line or the ground line to which the non-power port is connected, for example, the power line VDD0v6_sw of fig. 4 may inherit power set information of the power line VDD0V6 to which the power switch SW is connected, and thus, the power set information of the power line VDD0v6_sw may be determined by analyzing the configuration information of the power line VDD0V6 to generate the third cell design command.

By the method, the graphics connected with the first graphics can be automatically distinguished, so that the power set information of the power lines corresponding to the first graphics can be directly or indirectly analyzed.

In another case, in response to identifying at least one first graphic and only one second graphic in the power architecture diagram, a third cell design command corresponding to each first graphic may be determined based on a name of a power port to which the second graphic is connected.

Specifically, in the case where only one second pattern exists, it can be considered that only one ground line exists in the power supply structure pattern, and in this case, pairing information identifying the power supply line and the ground line may not be required, and it is defaulted that all the power supply lines are connected to the ground line.

Taking the power supply configuration of fig. 4 as an example, the fifth solid line 5, the sixth solid line 6, and the seventh solid line 7 are all connected to the same power supply port VSS, so it can be considered that there is only one ground line VSS to which each of the power supply lines VDD0V8, VDD0V6, and VDD0V6-SW can correspond, and accordingly, an example code of the generated third cell design command can be as follows:

“create_supply_set SS_VDD0V8 -function {power VDD0V8} -function {ground VSS}

create_supply_set SS_VDD0V6 -function {power VDD0V6} -function {ground VSS}

create_supply_set SS_VDD0V6_SW -function {power VDD0V6_SW} -function {ground VSS}”。

by the method, the corresponding relation between the power line and the ground line can be determined based on the configuration information of the unit patterns of the power line and the ground line, so that the design command of the power supply set can be automatically generated.

Further, according to an exemplary embodiment of the present application, the power supply design unit may include a power supply domain, and the target unit pattern may include a third pattern corresponding to the power supply domain, which may be, for example, but not limited to, a rectangle.

In this example, as shown in fig. 7, the cell design command corresponding to the target cell pattern may be determined by:

in step S710, third character information located inside the third graphic may be acquired from the configuration information of the third graphic.

Specifically, the user may configure a third graphic corresponding to the power domain when adding it, for example, input third character information, which may be displayed in the third graphic.

In step S720, the name of the power domain and design information inside the power domain may be determined based on the third character information.

The third character information may include, for example, a name of the power domain and design information inside the power domain, where the design information inside the power domain may indicate which designs are included inside the power domain, such as which elements are included.

As an example, as shown in fig. 4, the name of the power domain may be displayed at the upper left corner within the rectangle, and the design information inside the power domain may be displayed at the lower right corner within the rectangle. In addition, in the case where the power domain is a power domain that supplies power to the entire chip, design information inside the power domain may be written as "chip" or "".

In step S730, a cell design command corresponding to the third graphic may be determined based on the name of the power domain and the design information.

In the case of determining the name and design information of the power domain, a cell design command corresponding to the third graphic, for example, a command "create_power_domain" may be generated.

Further, a power supply for supplying power to a power domain corresponding to the third pattern may also be determined based on a unit pattern (to be described later) representing a power port connected to the third pattern.

Taking the power architecture shown in fig. 4 as an example, the cell design command corresponding to the third pattern "PD1" may be an example code as shown below:

“create_power_domain PD1 \

-elements {DUT1} \

-supply {primary SS_VDD0V8}”。

in the above code, "PD1" represents the name of the power domain, "DUT1" represents design information inside the power domain, and "ss_vdd0V8" represents a power supply that supplies power to the power domain.

By the method, the configuration information related to the third graph can be automatically analyzed, so that the unit design command related to the power domain can be automatically generated.

Further, according to an exemplary embodiment of the present application, the power supply design unit may include a power supply port, and the target unit pattern may include a fourth pattern corresponding to the power supply port, which may be, for example, but not limited to, a solid square.

In this example, as shown in fig. 8, the cell design command corresponding to the target cell pattern may be determined by:

in step S810, fourth character information located around the fourth graphic may be acquired from the configuration information of the fourth graphic.

Specifically, when adding the fourth graphic corresponding to the power port, the user may configure the fourth graphic, for example, may input fourth character information, which may be displayed around the fourth graphic. The fourth character information may include, for example, but is not limited to, a name of a power port (port_name).

In step S820, the name of the power supply port may be determined based on the fourth character information.

In step S830, a unit design command corresponding to the fourth graphic may be determined based on the name of the power port.

In the above step, the name of the power supply port may be acquired from the fourth character information, and a cell design command corresponding to the fourth graphic may be generated based on the name, for example, a command "create_supply_port" may be generated.

Taking the power architecture diagram of fig. 4 as an example, an example code of a generated cell design command corresponding to the fourth diagram may be as follows:

“create_supply_port VDD0V8

create_supply_port VDD0V6

by the method, the configuration information related to the fourth graph can be automatically analyzed, so that the unit design command related to the power port can be automatically generated.

Further, according to an exemplary embodiment of the present application, the power supply design unit may include a power switch, and the target unit pattern may include a fifth pattern corresponding to the power switch. The fifth image may be, for example, but not limited to, a circle having an "x".

In this example, as shown in fig. 9, the cell design command corresponding to the target cell pattern may be determined by:

in step S910, an input terminal, an output terminal, a control terminal, and a control manner of the power switch may be determined based on the configuration information of the fifth pattern.

Specifically, when adding the fifth pattern corresponding to the power switch, the user may configure the fifth pattern, and may specify, for example, an input terminal (input_supply_port), an output terminal (output_supply_port), a control terminal (control_port), and a control method of the power switch, where the control method may specify, for example, an on-state or off-state condition of the power switch.

In step S920, the name of the power switch may be determined based on the name of the power port to which the input terminal of the power switch is connected.

Here, the power switch may be named according to the name of the power port to which the input terminal of the power switch is connected, for example, the power switch SW as shown in fig. 4 may be named as "psw_vdd0V6" according to the name of the power port to which the input terminal thereof is connected, where "PSW" may indicate that it is a power port, and "VDD0V6" may indicate that it is a power port to which it is connected.

In step S930, a first power line connected to an input terminal of the power switch, a second power line connected to an output terminal of the power switch, a control unit connected to a control terminal of the power switch, and a control signal may be identified.

In step S940, a cell design command corresponding to the fifth pattern may be determined based on the name of the power switch, the input terminal, the output terminal, the control mode, the first power line, the second power line, the control unit, and the control signal.

Specifically, the input terminal information of the power switch may be generated based on the name of the first power line, for example, may be generated in a manner that "input terminal identifier" is combined with "name of the first power line"; the output information of the power switch may be generated based on the name of the second power line, for example, may be generated in a manner that "output identifier" is combined with "name of the second power line".

The control information may be generated based on a control unit (e.g., a Power Management Unit (PMU) in fig. 4) connected to the control terminal of the power switch and a control signal (e.g., "psw_ctrl" in fig. 4), for example, may be generated in a manner that the "control unit" is combined with the "control signal". Here, the control unit may be a unit connected to ports of the power switch other than the input terminal and the output terminal. In addition, the control mode of the user input can be any mode, for example, when EN is 1, the power switch is turned on and the power is turned on; when EN is 0, the power switch is turned off and the power is turned off.

Based on the above information, a cell design command corresponding to the fifth graphic may be generated, for example, a command "create_power_switch" may be generated. Taking the power architecture diagram of fig. 4 as an example, an example code of a generated cell design command corresponding to the fifth diagram may be as follows:

“create_power_switch PSW_VDD0V6 \

-input_supply_port {VDDI VDD0V6} \

-output_supply_port {VDDO VDD0V6_SW} \

-control_port {EN PMU/psw_ctrl} \

-on_state {on VDDI {EN}}”

in this way, the configuration information related to the fifth pattern can be automatically parsed to realize the automatic generation of the unit design command related to the power switch.

Further, according to an exemplary embodiment of the present application, the power supply design unit may include a level shifter, and the target cell pattern may include a sixth pattern corresponding to the level shifter. The sixth graphic may be, for example, but is not limited to, a triangle.

In this example, as shown in fig. 10, the cell design command corresponding to the target cell pattern may be determined by:

in step S1010, the name of the level shifter may be determined based on sixth character information located inside or around the sixth graphic acquired from the configuration information of the sixth graphic.

Specifically, when adding the sixth pattern corresponding to the level shifter, the user may configure the sixth pattern, for example, may input sixth character information, which may include, for example, but not limited to, names of the level shifters, for example, the names of the two level shifters in fig. 4 are "L2H" and "H2L", respectively.

In step S1020, a first power domain supplying power to the level shifter, a signal direction of the level shifter, and a voltage conversion direction may be determined based on the arrangement direction of the sixth pattern.

In this step, the direction of the sixth pattern set by the user may be recognized, and the first power domain, the signal direction, and the voltage conversion direction of the power supply may be determined. A first power domain connected to a long side having a connection line of a sixth pattern such as a triangle may be acquired, taking fig. 4 as an example, the power domain of the level shifter "L2H" is the power domain PD2, and the power domain of the level shifter "H2L" is the power domain PD1.

Furthermore, the direction of the signal may be identified based on the corners of the triangle with connecting lines. Specifically, the output of the first power domain may be determined according to the first power domain and the corner direction of the triangle, and the command "applies_to output" may be obtained. The voltage transition direction may also be determined based on the voltage magnitude and direction, such as from high to low ("high_to_low") or from low to high ("low_to_high").

In step S1030, a positional relationship of the level shifter and the first power domain may be determined based on the position of the sixth pattern with respect to the pattern corresponding to the first power domain.

In this step, it may be determined whether the level shifter is located outside or inside the first power domain according to a positional relationship between the sixth pattern and the pattern of the first power domain. Taking the level shifter "L2H" of fig. 4 as an example, according to the positional relationship of the graph, it may be determined that the level shifter "L2H" is located outside the first power domain "PD1", and thus the command "location parent" is obtained.

In step S1040, a cell design command corresponding to the sixth pattern may be determined based on the name of the level shifter, the first power domain, the signal direction, the voltage conversion direction, and the positional relationship.

Based on the above information, a cell design command corresponding to the sixth graphic may be generated, for example, a command "set_level_shift" may be generated. Taking the level shifter "H2L" in the power supply architecture diagram of fig. 4 as an example, an example code of the generated cell design command corresponding to the sixth diagram may be as follows:

“set_level_shifter H2L \

-domain PD1 \

-applies_to output \

-rule high_to_low \

-location parent”

in this way, the configuration information related to the sixth pattern can be automatically parsed to realize the automatic generation of the cell design command related to the level shifter.

Further, according to an exemplary embodiment of the present application, the power supply design unit may include an isolator, and the target unit pattern may include a seventh pattern corresponding to the isolator.

In this example, as shown in fig. 11, the cell design command corresponding to the target cell pattern may be determined by:

in step S1110, a control end, a control manner, and a clamping value of the isolator may be determined based on configuration information of the seventh pattern.

Specifically, when the user adds the seventh pattern corresponding to the isolator, the seventh pattern may be configured, for example, a control end, a control manner, and a clamp value (clamp_value) of the isolator may be specified, where the clamp value may default to 0, and the user may specify other values by modifying configuration information of the unit pattern.

In step S1120, a control unit connected to the control terminal of the isolator and a control signal may be identified.

In this step, control information may be generated based on a control unit (e.g., a Power Management Unit (PMU) in fig. 4) connected to the control terminal of the isolator and a control signal (e.g., "iso_ctl" in fig. 4), for example, may be generated in a manner that the "control unit" is combined with the "control signal".

In step S1130, an isolation direction of the second power domain supplying power to the isolator and the isolator may be determined based on the arrangement direction of the seventh pattern.

Here, the direction of isolation of the isolator may be determined according to the direction opposite to the side connected to the power domain, for example, resulting in the command "applies_to output".

In step S1140, the name of the isolator may be determined based on the name of the second power domain.

Here, the configuration information of the seventh graphic may include character information recorded in the seventh graphic, and the name of the isolator may be generated based on the character information and the name of the second power domain connected to the isolator, for example, may be generated in a manner that "character information in the seventh graphic" is combined with "the name of the second power domain".

In step S1150, a positional relationship of the isolator and the second power domain may be determined based on the position of the seventh pattern with respect to the pattern corresponding to the second power domain.

In this step, it may be determined whether the isolator is located outside or inside the second power domain according to a positional relationship between the seventh pattern and the pattern of the second power domain. Taking the isolator of fig. 4 as an example, according to the position relationship of the graph, it can be determined that the isolator is located outside the second power domain "PD3", and the command "location parent" is obtained.

In step S1160, a cell design command corresponding to the seventh graphic may be determined based on the name of the isolator, the control mode, the clamping value, the control cell, the control signal, the second power domain, the isolation direction, and the positional relationship.

Based on the above information, a cell design command corresponding to the seventh graphic may be generated, for example, a command "set_isolation" may be generated. Taking the isolator in the power architecture diagram of fig. 4 as an example, an example code of the generated cell design command corresponding to the seventh diagram may be as follows:

“set_isolation ISO_PD3 \

-domain PD3 \

-applies_to output \

-location parent \

-isolation_signal {PMU/iso_ctl} \

-isolation_sense high \

-clamp_value 0”。

Several examples of the cell design command to determine each target cell pattern in the power architecture diagram are described above, but it is not limited to the example process described above, and may be modified according to actual needs. Based on the unit design commands obtained in the examples above, in step S130, a power supply design command may be generated by combining the unit design commands together, taking the unit design command in the example above as an example, the code of the example power supply design command that may obtain the power supply architecture diagram of fig. 4 is as follows:
