For example, when integrated circuits realize various functions, different circuit units need to be designed, and corresponding power supply units, namely, corresponding power supply schemes need to be customized for the circuit units. When designing a power supply scheme, the attribute and the working strategy of the power supply unit need to be configured by using a specific tool, namely, a power supply instantiation file for describing an instantiation power supply working strategy is created, and then a complete power supply scheme is configured based on the power supply instantiation file.

Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
Referring to fig. 1, fig. 1 is a flowchart illustrating an implementation method of a power scheme according to an embodiment of the present application. In all embodiments of the present application, the simulation method of the power supply scheme is used for simulating the working condition of the power supply scheme in the circuit, and the execution subject is a computer terminal device, for example, a computer or a server for designing the power supply scheme and performing simulation operation on the power supply scheme.
The simulation method of the power supply scheme shown in fig. 1 comprises the following steps:
S11: acquiring a power supply instantiation file and a simulation path instantiation file; the power supply instantiation file is used for describing the working strategy of the instantiation power supply, and the simulation path instantiation file is used for describing the instantiation path of the instantiation power supply.
In S11, the power supply instantiation file and the simulation path instantiation file are both files obtained by the instantiation tool configuration. The power supply instantiation file is used for describing the working strategy of the instantiation power supply, and the simulation path instantiation file is used for describing the instantiation path of the instantiation power supply.
It should be noted that, in the design process of an integrated circuit, since a plurality of functional units are involved in one integrated circuit, an exemplary power supply for each functional unit needs to be designed, so as to obtain a complete power supply scheme. When the power supply scheme is designed, the instantiation power supply can be used as a power supply node, the functional unit corresponding to the power supply node is a power receiving circuit, namely, an instantiation path, and different instantiation power supplies correspond to different instantiation paths.
It will be appreciated that in all embodiments of the application, since the power scheme is a power scheme that instantiates functional units in the integrated circuit, the power scheme has different partitioned instantiated power for different functional units, i.e., includes at least two sets of instantiated power. When the instantiation power supplies of different partitions of the power supply scheme have the same power consumption intention, the instantiation power supplies of different partitions can be mapped by the same power supply instantiation file.
It should be noted that, since the hardware description language does not support the description of the power connection, when the operation process of the power scheme is emulated, a unified power consumption format (Unified Power Format, UPF) file (i.e., UPF file) and a register conversion stage circuit (REGISTER TRANSFER LEVEL, RTL) script file (i.e., RTL script file) need to be extended to describe the power switch and its connection.
In this embodiment, the power instantiation file is a UPF file edited using the tool command language (Tool Command Language, TCL) that describes the operational policies of the instantiation power. The simulation path instantiation file is an RTL script file, is edited based on a Very High-speed integrated circuit hardware description language (VHDL) or a Verilog language, and is used for describing an instantiation path of an instantiation power supply.
It should be explained that, since most circuits can be regarded as storing binary data by registers or performing data processing by logic operations between registers, the flow of data processing is controlled by a time sequence state machine, these processes and controls can be described in a hardware description language, so that the RTL script file can describe the functions achieved by an ideal circuit in a hardware description language (Verilog or VHDL), the gate level is a function of implementing the circuit by a specific logic unit, and the gate level can be finally processed into actual hardware in a semiconductor factory. RTL and gate level are different stages in design realization, and RTL obtains the gate level after logic synthesis.
As for the timing of acquiring the power supply instantiation file and the simulation path instantiation file, the following two scenarios may be included, but are not limited to.
Scene 1: and when a preset instruction for configuring the power supply scheme is detected, acquiring a power supply instantiation file and a simulation path instantiation file.
For example, when a power supply scheme is configured for a functional unit in an integrated circuit, a preset instruction of a new project is initiated in a power supply scheme tool, and then a configuration component is called to acquire a power supply instantiation file and a simulation path instantiation file; the power supply scheme tool is provided with a configuration component and a simulation component in advance, wherein the configuration component is used for assisting in creating and configuring a power supply scheme, and the simulation component is used for performing simulation operation on a circuit scheme.
Scene 2: when a preset instruction for performing simulation operation on the power supply scheme is detected, a power supply instantiation file and a simulation path instantiation file are obtained.
For example, after a power scheme is configured by a power scheme tool, the preset instruction is triggered, and then a simulation component is called to obtain a power instantiation file and a simulation path instantiation file corresponding to the power scheme, wherein the power scheme tool is pre-configured with the simulation component, and the simulation component is used for performing simulation operation on a circuit scheme.
S12: according to a preset top-level file configuration strategy, a top-level file for describing a power supply scheme is obtained based on the power supply configuration file and the simulation path instantiation file configuration; the information in the top-level file is used for describing the corresponding relation between each instantiated power supply and the instantiated path in the power supply scheme.
In S12, the top-level file configuration policy is a method for describing the top-level file configuration based on the power configuration file and the simulation path instantiation file. That is, the top level file is a script file configured based on the power supply configuration file and the simulation path instantiation file.
It should be noted that, when the power schemes of the different instantiation power sources have the same power consumption intention, the instantiation power sources can be mapped from the same power source instantiation file, so in the top-level file, the instantiation power sources corresponding to different instantiation paths can be pointed to the same power source instantiation file by configuring corresponding pointing sentences. Meanwhile, the information in the top-level file can also be used for describing the corresponding relation between each instantiation power supply and an instantiation path in the power supply scheme, so that when the power supply scheme is simulated, because the instantiation power supplies correspond to different instantiation paths, even if different instantiation power supplies point to the same power supply instantiation file, different instantiation power supplies can be driven by different instantiation paths, and the phenomenon that only one instantiation power supply is driven is avoided.
As one possible implementation of this embodiment, a top-level file configuration policy is used to describe the configuration of the directed statements. Based on this, S12 specifically includes:
Determining the number N of the instantiated power supplies based on the simulation path instantiation file; wherein N is an integer greater than 1; according to the configuration mode of the pointing statement, based on the power supply configuration file and the simulation path instantiation file, configuring N sections of first pointing statement and N sections of second pointing statement; and combining the N sections of the first pointing sentences and the N sections of the second pointing sentences to obtain a top-level file.
In this embodiment, the top-level file configuration policy is used to define a configuration method of the directed statement, where the configuration manner of the directed statement may include a configuration manner of a first directed statement and a configuration manner of a second directed statement, where the first directed statement is used to define or distinguish an instantiated power supply in the circuit scheme, the second directed statement is used to define or distinguish an instantiated path, and the first directed statement and the second directed statement are in one-to-one correspondence with each other.
It should be noted that, different key fields, namely, a first key field and a second key field, are respectively defined in the configuration mode of the first pointing sentence and the configuration mode of the second pointing sentence.
Taking the example that the power instantiation file is inst_module.upf and the first key field is load_ upf as an example, the configuration of the N segments of first pointing statements based on the power configuration file according to the configuration mode of the pointing statements may be:
load_ upf instA, load_ upf instA2, … … load_ upfinstAN, wherein load_ upf represents an exemplary power supply in the power scheme, instA1, instA2, … … instAN are serial numbers or names of the exemplary power supplies.
Based on the above embodiment, the second key field is a scope, and according to the configuration mode of the pointing statement, based on the simulation path instantiation file, the configuration to obtain N segments of second pointing statement may be:
scope instA1, scope instA, … … scope instAN, wherein scope represents an instantiation path corresponding to an instantiation power in the power scheme, and instA, instA2, … … instAN are serial numbers or names of the instantiation power.
The top file obtained by combining the N sections of the first pointing statement and the N sections of the second pointing statement is named as an asec_top.upf, that is, in the top file asec_top.upf, load_ upf instA1, load_ upf instA2 and … … load_ upfinstAN are respectively used for pointing to N instantiation power sources, and scope instA1, scope instA2 and … … scope instAN are respectively used for pointing to N instantiation paths corresponding to the N instantiation power sources one by one.
In this embodiment, the N sections of first pointing statements and N sections of second pointing statements are combined, which may be to perform field splicing on each section of first pointing statement and each section of second pointing statement, and fill each section of first pointing statement and each section of second pointing statement into a script template correspondingly, so as to obtain a top-level file. Because the top-level file configuration strategy is used for describing the configuration mode of the directed sentences, the N sections of first directed sentences and N sections of second directed sentences obtained by configuration can be respectively used for defining or distinguishing the instantiated power supply and the instantiated path based on the power supply configuration file and the simulation path instantiation file according to the top-level file configuration strategy. The corresponding relation between each instantiation power supply and each instantiation path is defined from the script editing layer, and the association between the instantiation power supply and the instantiation paths is realized, so that the association relation between the instantiation power supply and the instantiation paths must be followed when the power supply scheme is simulated, and a reliable and accurate foundation is provided for the simulation operation of the power supply scheme.
As one possible implementation manner of this embodiment, the steps are as follows: determining the number N of the instantiated power supplies based on the simulation path instantiation file comprises the following steps: analyzing the simulation path instantiation file to determine the number X of instantiation paths; wherein X is an integer greater than 1; and identifying the number X of the instantiation paths as the number N of the instantiation power sources.
In this embodiment, since the simulation path instantiation file is used to describe the instantiation paths of the instantiation power source, and different instantiation power sources correspond to different instantiation paths, the number of instantiation paths described by the simulation path instantiation file can be determined based on the simulation path instantiation file.
It should be noted that, the simulation path instantiation file may be an RTL script file, which is edited based on VHDL language or Verilog language, and by configuring a corresponding identifier or annotation in the RTL script file, different instantiation paths corresponding to different instantiation power sources may be distinguished.
In this embodiment, the simulation path instantiation file is parsed, specifically, the RTL script file is parsed by a script compiling tool or a script parsing tool, so as to determine the number X of instantiation paths, and determine the number N of instantiation power sources based on the number X of instantiation paths, that is, identify the number X of instantiation paths as the number N of instantiation power sources, that is, assign the number X of instantiation paths as the number N of instantiation power sources.
In this embodiment, the number X of the exemplary paths and the number N of the exemplary power supplies are used only to distinguish the meaning of the number of the exemplary paths and the number of the exemplary power supplies on the physical level, and are not used to distinguish the actual values. In practical application, after the number of the instantiation paths is assigned to the number of the instantiation power sources, the meaning of the instantiation paths and the instantiation power sources on a physical level is not affected.
It can be appreciated that in other embodiments, since the emulation path instantiation file can be given to the requirements of the functional units in the integrated circuit, when the emulation path instantiation file is created, the attribute information of the emulation path instantiation file is configured, and thus the number of instantiation paths can be determined from the attribute information of the emulation path instantiation file. For example, the number X of instantiation paths may be determined from attribute information of an emulation path instantiation file, that is, attribute information of an RTL script file, and then the number X of instantiation paths may be identified as the number N of instantiation power sources.
In practical application, since the power supply instantiation file and the simulation path instantiation file are existing ready resources, and the power supply instantiation file is customized on the premise of the simulation path instantiation file, the instantiation path of the instantiation power supply described by the simulation path instantiation file is necessarily related to the working strategy of the instantiation power supply described by the power supply instantiation file, and the number X of the instantiation paths and the number N of the instantiation power supply are determined and identified, so that the number of segments of the first pointing statement and the number of segments of the second pointing statement to be configured can be skillfully determined, and the configuration efficiency and accuracy of the top-level file are improved to a certain extent.
S13: executing a preset simulation script, and performing simulation operation of a power supply scheme according to the top-level file and the simulation path instantiation file.
In S13, the simulation script is a script file for describing the power scheme simulation content or the simulation process.
It should be noted that, because the information in the top-level file is used for describing the correspondence between each instantiated power supply and an instantiated path in the power supply scheme, and the simulation path instantiation file is used for describing the instantiated path of the instantiated power supply, when executing the simulation operation of the power supply scheme according to the top-level file and the simulation path instantiation file by the preset simulation script, the simulation operation can be performed based on the correspondence between each instantiated power supply and an instantiated path in the power supply scheme, that is, the driving of each instantiated power supply in the power supply scheme is realized, and meanwhile, the working process between each instantiated power supply and an instantiated path in the power supply scheme is simulated. The phenomenon that an instantiation power supply is not driven in the circuit scheme simulation process, so that an inaccurate simulation result is caused is avoided.
As one possible implementation manner of this embodiment, S13 specifically includes: importing the preset simulation script, the top-level file and the simulation path instantiation file into a simulation tool; executing the preset simulation script through the simulation tool, and constructing an execution environment for the top-level file and the simulation path instantiation file; and executing the top file and the simulation path instantiation file to perform simulation operation of a power supply scheme under the execution environment by the simulation tool.
In this embodiment, the simulation tool may be a compiled Verilog simulator, such as a VCS simulation tool. The VCS simulation tool supports the Verilog HDL language, PLI and SDF of the OVI standard, and a graphical user interface, such as Virsim graphical user interface, can be integrated in the VCS simulation tool, so that a foundation is provided for interaction and post-processing of simulation results.
It should be noted that, when simulating different power schemes, a simulation environment, that is, an execution environment, of the different power schemes may be configured. In this embodiment, a build statement of an execution environment is defined in a preset simulation script, and the execution environment can be built for a top-level file and a simulation path instantiation file by executing the preset simulation script through a simulation tool. After the execution environment is built, executing the top-level file and the simulation path instantiation file in the execution environment through a simulation tool to realize the simulation operation of the power supply scheme.
As a possible implementation manner of this embodiment, the preset simulation script includes a power scheme pointing statement. The steps are as follows: executing the preset simulation script through the simulation tool, and constructing an execution environment for the top-level file and the simulation path instantiation file, wherein the execution environment comprises the following steps:
Executing the power scheme pointing statement through the simulation tool, and constructing an execution environment for the power scheme described by the top-level file and the instantiation path described by the simulation path instantiation file.
In this embodiment, the power scheme pointing statement is used to point to the power scheme being emulated before the emulation operation, while also providing the power scheme with the execution environment required for the emulation operation.
It should be noted that the power scheme pointing statement includes a key field for pointing to the top-level file, and a key field for pointing to each instantiated power in the power scheme characterized by the top-level file.
Taking the example that the key field pointing to the top-level file is power_ topasic _top, the key field is used to point to the top-level file, that is, to determine the power scheme that needs to perform the emulation operation. In this embodiment, the top file is an asic_top. Upf, and accordingly, the complete power scheme pointing statement is:
power_topasic_topasic_top.upf
taking the example that the key field pointing to the instantiated power supply is power_inst, the key field is used for pointing to the instantiated power supply in the power supply scheme characterized by the top-level file, that is, defining the simulation time of the instantiated power supply in the simulation operation process. In this embodiment, the exemplary power sources are instA1, instA2, … … instAN, and correspondingly, the exemplary power source pointing statement in the power scheme characterized by the top-level file is:
power_inst A1
power_instA2
……
power_instAN
Wherein power_insta1 points to the first instantiated power supply in the power scheme characterized by the top-level file, or the instantiated power supply named A1, and so on, power_ instAN points to the nth instantiated power supply in the power scheme characterized by the top-level file, or the instantiated power supply named AN.
In this embodiment, a power scheme pointing statement is defined in a preset simulation script, so when the simulation of the power scheme is performed, an execution environment can be built for the corresponding top-level file and the simulation path instantiation file according to the power scheme pointing statement, that is, the corresponding top-level file and the instantiation power in the power scheme represented by the top-level file are determined, and further an implementation basis is provided for the simulation operation.
As one possible implementation manner of this embodiment, the steps are as follows: executing the top file and the simulation path instantiation file to perform simulation operation of a power supply scheme under the execution environment by the simulation tool, wherein the simulation operation comprises the following steps:
Determining each target instantiation power supply from the power supply scheme according to each section of the first pointing statement by the simulation tool in the simulation environment, and determining a target instantiation path corresponding to each target instantiation power supply according to each section of the second pointing statement; and carrying out simulation operation on each target instantiation power supply based on the target instantiation path corresponding to each target instantiation power supply through the simulation tool.
In this embodiment, each target instantiation power supply is determined from the power supply scheme according to each segment of the first directive statement, that is, a corresponding target instantiation power supply is determined from the top-level file according to each segment of the first directive statement, and a corresponding target instantiation path of each target instantiation power supply is determined according to each segment of the second directive statement, that is, a corresponding target instantiation path of each target instantiation power supply is determined from the simulation path instantiation file according to each segment of the second directive statement.
As can be seen from the foregoing, in the simulation method for a power supply scheme provided in this embodiment, the obtained power supply instantiation file and the simulation path instantiation file are configured into the top-level file for describing the power supply scheme according to the preset top-level file configuration policy, and because the information in the top-level file is used for describing the correspondence between each instantiation power supply and each instantiation path in the power supply scheme, by executing the preset simulation script, the simulation operation on all instantiation power supplies included in the power supply scheme can be implemented according to the top-level file and the simulation path instantiation file, so that the phenomenon that simulation driving cannot be performed on all instantiation power supplies is avoided, and the simulation of the power supply scheme is more accurate.
Referring to fig. 2, fig. 2 is a flowchart illustrating an implementation method of a power scheme according to another embodiment of the application. Compared with the corresponding embodiment of fig. 1, the simulation method of the power supply scheme provided in this embodiment further includes S21 to S23 after S13. The details are as follows:
s21: and obtaining target data of the simulation operation.
S22: and calling a data summarizing tool to manufacture a data display file according to the target data.
S23: and displaying the data display file.
In this embodiment, the target data is data obtained by simulating a working condition under the condition that the target instantiation power source and the target instantiation path are associated when the power source scheme is subjected to the simulation operation. The data summarization tool is a plug-in tool for making data presentation files.
