Description
Technical Field
The present invention relates to the field of circuit design, and in particular, to a method and an apparatus for constraining edit timing, a computer device, and a storage medium.
Background
Timing analysis is one of the important steps in the design of timing circuits, and the quality of the timing analysis directly affects the product development result. Timing analysis is generally divided into dynamic timing analysis and static timing analysis, wherein static timing analysis is the mainstream analysis method adopted by current timing analysis, and does not care about the functionality of a circuit, but determines whether a designed circuit meets the timing requirement according to a circuit netlist and a timing constraint condition. The static timing constraints have two main roles: firstly, the designed working frequency is improved, and for the digital circuit design, the improvement of the working frequency is important, and the high working frequency corresponds to high chip processing capacity; and secondly, obtaining a correct time sequence analysis report, wherein the static time sequence analysis takes the constraint as a standard for judging whether the time sequence meets the design requirement, and the correct time sequence analysis report can be obtained only if the time sequence constraint is correctly input.
At present, a user generally writes a timing constraint command to add a static timing constraint, but as the design scale is larger and larger, more ports, connecting lines and basic unit devices are designed, so that the user manually writes the timing constraint more and more complicated and is prone to errors. How to realize accurate timing constraint on a complex timing circuit design becomes a problem to be solved urgently.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The editing time sequence constraint method provided by the embodiment of the invention is applied to an editing time sequence constraint system, the editing time sequence constraint system comprises a client and a server, and the client and the server are communicated through a network and are used for simply and quickly completing time sequence constraint in a time sequence circuit design process. The client is also called a user side, and refers to a program corresponding to the server and providing local services for the client. The client may be installed on, but not limited to, various personal computers, laptops, smartphones, tablets, and portable wearable devices for human-computer interaction with a user. The server may be implemented as a stand-alone server or as a server cluster consisting of a plurality of servers.
In an embodiment, as shown in fig. 1, an edit timing constraint method is provided, which is described by taking the server in fig. 1 as an example, and specifically includes the following steps:
s10, acquiring a time sequence constraint command editing request, and entering a time sequence constraint editing interface based on the time sequence constraint command editing request, wherein the time sequence constraint editing interface comprises a netlist analysis element display area, a time sequence constraint command management area and a time sequence constraint command display area.
Wherein, the timing constraint command editing request is a request sent by a developer to an editing timing constraint system to edit the timing constraint of the target element in the netlist design file. The netlist design file is a source file for displaying the specific positions of basic elements such as basic unit devices, wires and ports on the netlist and the wire relation between each basic unit device or port.
As shown in fig. 2, the timing constraint editing interface is an interface of the netlist parsing element display area, the timing constraint command management area, and the timing constraint command display area. The netlist analyzing element display area is used for displaying basic elements such as each port, connecting line and basic unit device in the netlist design file. The timing constraint command management area is used for displaying each preset basic timing management command. The basic timing constraint command is a command preset in the edit timing constraint system for all the basic elements that can edit the timing command, for example, the basic timing constraint command includes a timing constraint for editing a maximum path or a minimum path, and the like, which is not limited herein.
The time sequence constraint command display area is used for displaying a target time sequence constraint command formed after the time sequence command is edited on the target element.
Specifically, the edit timing constraint system may receive the netlist design file, analyze the netlist design file to obtain at least one basic element corresponding to each element type, and display the basic elements in the netlist analysis element display area according to the element types. Meanwhile, the editing time sequence constraint system can also display at least one preset basic time sequence constraint command which is displayed in a classified mode according to the time sequence constraint types in the time sequence constraint command management area.
In step S10, after receiving the time sequence constraint command editing request, the editing time sequence constraint system may enter a time sequence constraint editing interface, which is beneficial for developers to edit commands of the target element on the graphical interface based on the netlist parsing element display area and the time sequence constraint command management area provided by the time sequence constraint editing interface, and is simple and fast, thereby improving the accuracy and rapidity of inputting the target time sequence constraint command.
And S20, analyzing at least one basic element displayed in the element display area based on the netlist, and determining a target element.
The basic element is each element displayed in the netlist resolution element display area, and includes, but is not limited to, elements corresponding to element types such as basic unit devices, wires, and ports. For example, for port types, the basic elements include port one, port two, port three, and so on.
The target element is a basic element selected based on the current timing constraint command editing request to edit the timing command.
In step S20, the edit timing constraint system may receive a basic element selected by the developer from the netlist analysis element display area as the target element, and the selection method is convenient and fast, so as to avoid the developer from performing map search in the netlist design file and then performing target element confirmation, thereby improving the efficiency and accuracy of obtaining the target element.
And S30, determining a time sequence constraint command to be edited based on at least one basic time sequence constraint command displayed in the time sequence constraint command management area.
The basic timing constraint command is a command preset in the edit timing constraint system for editing all target elements that can edit the timing command, for example, the basic timing constraint command includes a timing constraint for editing a maximum path or a minimum path, and the like, which is not limited herein.
In step S30, the editing timing constraint system can receive a basic timing constraint command selected by the developer from the timing constraint command management area as the timing constraint command to be edited, the selection is convenient and fast, the developer is prevented from memorizing a large number of basic timing constraint commands and manually inputting the timing constraint command to be edited, and the efficiency and accuracy of obtaining the timing constraint command to be edited are improved.
And S40, entering a corresponding command editing graphical interface based on the target element and the time sequence constraint command to be edited, wherein the command editing graphical interface comprises at least one command parameter option.
The command editing graphical interface is a graphical interface used for parameter editing of the timing constraint command to be edited, and is beneficial for developers to intuitively know each command parameter option to be filled based on the graphical interface, as shown in fig. 3.
The command parameter options are specifically included in each to-be-edited timing constraint command, and are used for a user to add a timing constraint parameter value according to a timing constraint test scenario, for example, for the to-be-edited timing constraint command to create a clock, the included command parameter options include a clock name (clock _ name), a clock period (period), a time frequency (frequency), a clock peak value (rising), a clock valley value (falling), an object (object), and the like.
In step S40, the editing timing constraint system may enter a command editing graphical interface including at least one command parameter option after receiving the confirmed target element and the timing constraint command to be edited, which is beneficial for developers to intuitively know each command parameter option to be filled based on the graphical interface, and it is not necessary to memorize the editing code of the command parameter option by themselves, thereby improving the efficiency of editing the constraint timing command.
S50, obtaining a command parameter option value corresponding to the command parameter option based on at least one command parameter option in the command editing graphical interface, and generating a target time sequence constraint command corresponding to the target element.
The command parameter option value is a timing constraint parameter value of the test scenario corresponding to the command parameter option, for example, for time frequency, the command parameter option value may be 100 MHz.
The target time sequence constraint command is a complete command for carrying out time sequence constraint on the target element, which is formed after adding corresponding command parameter option values to each command parameter option in the time sequence command to be edited.
Specifically, the editing timing constraint system may sequentially read the command parameter option values filled in each command parameter option, add the command parameter option values to the timing command to be edited, and form the target timing constraint command.
In step S50, the edit timing constraint system can automatically read each command parameter option value to generate a target timing constraint command corresponding to the target component, thereby improving the efficiency and accuracy of generating the target timing constraint command.
And S60, displaying the target time sequence constraint command in a preset display mode on the time sequence constraint command display area.

In step S60, the editing timing constraint system may display the target timing constraint command on the timing constraint command display area according to a preset display manner, which is beneficial for developers to clearly view command parameters, specifically command parameter options and corresponding command parameter option values, for implementing the target timing constraint command on the target element.
In the editing timing constraint method provided by the embodiment, the editing timing constraint system enters a timing constraint editing interface by acquiring a timing constraint command editing request, a netlist analysis element display area on the timing constraint editing interface determines a target element, a to-be-edited timing constraint command is determined in a timing constraint command management area, the to-be-edited timing constraint command adopted for the target element can be visually and effectively confirmed, developers do not need to manually input the target element and the to-be-edited timing constraint command, and the efficiency and the accuracy are improved; meanwhile, a command editing graphical interface can be generated based on the target element and the time sequence constraint command to be edited, so that developers can conveniently perform parameter editing on the time sequence constraint command to be edited on the graphical interface, the process of performing parameter editing on the time sequence constraint command to be edited is simple and easy to use, and the accuracy and the efficiency of inputting the time sequence constraint command are improved; finally, the target time sequence constraint command formed by the edited time sequence constraint command to be edited can be displayed on the time sequence constraint command display area, so that developers can easily view command parameters for implementing the target time sequence constraint command on the target element, and the engineering design development efficiency is obviously improved.

s111, obtaining a netlist design file, analyzing the netlist design file, obtaining at least one element type and at least one basic element corresponding to each element type, and forming a classification element table.
The component types are types of various components included in the netlist design file, and in this embodiment, the component types include three types, namely a port, a line and a basic unit device.
The classification element list is formed by the editing sequential constraint system based on classification statistics of each port, connecting line and basic unit device in the netlist design file, and records all basic elements included in each element type. For example, for a port, this element type includes port one, port two, etc.
In step S111, the edit timing constraint system creates a classified component table to facilitate the subsequent rapid and accurate import of each component type recorded according to the table into each base component.
And S112, classifying the classified component table by adopting a netlist analysis interface pre-configured on the netlist analysis component display area so as to display at least one basic component corresponding to each component type on the netlist analysis component display area according to a first preset display structure in a classified mode.
The netlist parsing interface is used for reading the component classification table and importing each basic component included in the component classification table into the interface of the editing timing constraint system.
The first predetermined display structure is a predetermined structure for displaying each basic element, such as a tree structure or a Hierarchical structure, and is not limited herein.
In step S112, the edit timing constraint system may display at least one basic element corresponding to each element type according to the first preset display structure, so as to facilitate a developer to quickly query the corresponding basic elements in sequence according to the element types.

The editing time sequence constraint system can display at least one basic element corresponding to each element type in a classified mode according to a first preset display structure, and developers can conveniently and rapidly inquire the corresponding basic elements in sequence according to the element types.
In one embodiment, the netlist resolution device display area includes a device search field and a device presentation field. As shown in fig. 5, in step S20, determining the target component based on the at least one basic component displayed in the netlist resolving component display area includes:
s21, receiving a component search instruction obtained based on the component search column, wherein the component search instruction comprises a component keyword.
The element search column is used for reading element keywords manually input by a developer. The column is established, so that a developer can find the corresponding basic elements more quickly through the edit timing constraint system without inquiring the required target elements one by one from the netlist resolution element display area.
The element display column is a column for displaying each base element. The component search instruction is an instruction to search for each base component including the key keyword. The element keyword is a word included in the name corresponding to the target element to be found.
In step S21, the editing timing constraint system may accept a component search command including a component keyword obtained based on the component search field, and prepare a data base for subsequently querying a corresponding target component in the classified component table based on the component keyword.
S22, inquiring the classified component table based on the component keywords, obtaining at least one basic component corresponding to the component keywords, and displaying the at least one basic component corresponding to the component keywords on a component display column of the netlist analysis component display area.
In step S22, the editing timing constraint system can quickly search out at least one basic element corresponding to the element keyword from the classified element table, and display at least one basic element containing the element keyword in the element display bar, so that developers can intuitively obtain at least one basic element corresponding to the element keyword from the element display bar in time for further screening, and finally obtain the target element.
And S23, receiving a component selection instruction triggered by any basic component on the netlist analysis component display area, and determining a target component.

In steps S21 through S23, the editing timing constraint system may accept a component search command including a component keyword obtained based on the component search field, and prepare a data base for a subsequent query of a corresponding target component in the sorted component table based on the component keyword. The editing time sequence constraint system can quickly inquire at least one basic element corresponding to the element key words in the classification element table, and at least one basic element containing the element key words is displayed in the element display bar, so that developers can visually and further screen the at least one basic element corresponding to the element key words displayed on the element display bar, and finally obtain the target element. The editing time sequence constraint system performs preliminary screening on all basic elements to obtain simplified basic elements and provides the simplified basic elements for developers, and determines a target element through an element selection instruction, so that the efficiency of selecting the target element can be improved, and the efficiency of editing a time sequence constraint command is improved.

The basic timing constraint command is a command preset in the edit timing constraint system for editing all the target elements that can edit the timing command, for example, the basic timing constraint command includes a timing constraint for editing a maximum path or a minimum path, and the like, and is not limited herein.
In step S121, the editing timing constraint system obtains the timing constraint command table, reads each basic timing constraint command according to each timing constraint type in the timing constraint command table, and prepares a data base for a timing constraint command management area for subsequently importing each basic timing constraint command into the editing timing constraint system.

The command management interface is used for reading each basic timing constraint command in the timing constraint command table to an interface on the timing constraint command management area.
The second predetermined display structure is a predetermined structure for displaying each basic timing constraint command, such as a tree structure or a Hierarchical structure, and is not limited herein.
In step S122, the edit timing constraint system may display at least one basic timing constraint command corresponding to each timing constraint category according to a second preset display structure, so as to facilitate a developer to sequentially and rapidly query the corresponding basic timing constraint commands according to the timing constraint categories.
