Description

TECHNICAL FIELD

[0001] The present application is suitable for the chip digital back-end technical field, and particularly relates to an electronic design automation tool configuration method and system and related equipment. BACKGROUND

[0002] Electronic design automation (EDA) tool refers to a software tool using computer-aided design (CAD) technology to complete the functional design, synthesis, verification, physical design and other processes of very large scale integrated circuit (VLSI) chips. When using electronic design automation tools for digital back-end work, a variety of input files need to be provided to the electronic design automation tool, including library files. The function of the library file is to provide timing, physical and other information for the functional module during electronic design automation operation. Different library files have an important influence on the timing convergence of the layout and wiring of the functional module, so different modules need to be configured with different library files.

[0003] In related technologies, all functional modules share the same environment, and all library files are integrated in the environment. The purpose is to meet the needs of all functional modules as much as possible, and then the functional modules query related values in all library file sets according to their own needs. If some modules have additional library file requirements, manual modification is required, and the specific path is queried manually and added to the environment.

[0004] However, if all library files are configured for the functional module, some unnecessary files will be read, which will cause the running time to become longer. At the same time, some functional modules need to be configured with additional special library files, and this part cannot meet the requirements if only the general library files are used. In addition, when the functional module is large and has many sub-modules, the library files of the sub-modules also need to be configured. At this time, the library files are relatively cumbersome and prone to missing. SUMMARY

[0005] The present application provides an electronic design automation tool configuration method, system and related equipment, which aims to solve the technical problems of complicated library file configuration process and large scale in existing automation tools.

[0006] To solve the above technical problems, in a first aspect, the present application provides an electronic design automation tool configuration method, which comprises the following steps:

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0040] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating the steps of an electronic design automation (EDA) tool configuration method provided in an embodiment of the present invention. The EDA tool configuration method includes the following steps:

[0041] S101. Obtain module information of each functional module in the electronic design automation tool, as well as library file information of the library files required by each functional module, wherein each module information includes connection relationship information between the functional module and the next-level sub-functional module connected to it.

[0042] The main purpose of step S101 is to configure the module information of each functional module outside of the configuration process of the electronic design automation tool. During the implementation process, the module information includes the module name, the name of the next-level sub-functional module connected to it, and the names of other required functional modules. The next-level sub-functional module connected to it can have a calling relationship or an inclusion relationship with the functional module. The configuration of the module information can be implemented in text form, but the readability of the text must be ensured.

[0043] As described in the background section, the library file is a file that a functional module needs to call. Determining the library file that the functional module needs to call in step S101 is beneficial for subsequent steps to analyze the configuration requirements of the functional module. Generally, in a computer system, the electronic design automation tool is deployed as software, while the library file is independent of the electronic design automation tool and stored in the computer system's storage space. The electronic design automation tool loads and uses the library file by accessing its storage path in the storage space.

[0044] S102. Based on the module information, obtain the module set information of all sub-functional modules connected to the functional module.

[0045] Specifically, step S102 includes the following sub-steps:

[0046] S1021. Starting with the current functional module, traverse according to the connection relationship information to obtain the module information of the current functional module, and determine whether the next-level sub-functional module connected to the current functional module is empty based on the connection relationship information in the module information: if not, proceed to step S1022; if yes, exit the loop, accumulate the module information of all the sub-functional modules connected to the current functional module to obtain the module set information;

[0047] S1022. Traverse to the next level of the sub-functional module of the current functional module and return to step S1021.

[0048] In this embodiment of the invention, the module information includes information about the current functional module and its connected next-level sub-functional modules. Therefore, the functional module can be used as the parent node and the sub-functional modules as child nodes. Through depth-first traversal, a set of all functional modules with the current functional module as the main component can be obtained. It is understood that in the electronic design automation tool, all functional modules belonging to the same module set information should be all modules required to achieve a certain task. For example, in the chip digital back-end design process, the design tool should include all modules related to chip functional design. However, the electronic design automation tool is not only used for chip design; it can also implement design functions such as integrated circuits. But the selection and invocation of functional modules are different for different types of design flows. This embodiment of the invention, through steps S101 and S102, determines the functional modules that need library file configuration through information configuration and module traversal, so as to subsequently implement the library file configuration process for the corresponding functional modules.

[0049] S103. Based on the module set information and the library file information, classify and match the library files required by different functional modules to obtain the configuration path data of the library files.

[0050] Specifically, step S103 includes the following sub-steps:

[0051] S1031. Based on the module information of the functional module and the module set information corresponding to the functional module, obtain the library file information set of the library file information required by each of the functional modules.

[0052] S1032. Based on the library file information set, classify and match different library files to obtain named files corresponding to the library files with category information;

[0053] S1033. Based on the naming file of the library file according to the different category information, obtain the corresponding library file configuration path data by concatenating the paths.

[0054] Specifically, the naming file is:

[0055] The named file is obtained by combining the module information, the type of classification matching of the library file, and the suffix of the library file as terms.

[0056] In step S1032, the classification and matching of library files can be performed according to file name and type. For example, library files include timing library files, physical library files, etc. In computer systems, different types of library files have different naming conventions, but library files of the same type have the same naming convention. During implementation, different regular expressions can be used to concatenate file name entries for different library files. For example, for a timing library file lib, the standard naming convention for functional modules is "standard unit / interface module + scenario + '.lib.gz'", where scenario represents different PVT environments. Following this method, step S1032 can generate corresponding regular expressions for naming various types of library files.

[0057] The library file configuration path data is specifically as follows:

[0058] The library file configuration path data is obtained by combining the path of the type matching the library file category and the named file as terms.

[0059] Specifically, in a computer system, different types of library files are stored in different paths, but the storage path for library files of the same type is fixed. Therefore, in step S1033, the entire path can be concatenated using the same path terminology, and the same type of library files can be concatenated using the fixed path and the filename of the named file.

[0060] S104. The configuration path data is deduplicated to obtain simplified library file configuration path data.

[0061] Through step S103, this embodiment of the invention obtains library file configuration path data for all library files required by all functional modules under a parent node functional module. However, as described in the background art, different functional modules have both inclusion and calling relationships. Therefore, when different functional modules run, they will load their respective required library files. This loading relationship will also be reflected in the various path entries of the library file configuration path data, which will cause excessive loading time and duplicate loading. Therefore, it is necessary to perform deduplication processing based on the content of each path entry in the library file configuration path data to reduce the size of the library file configuration path data and thus reduce loading time.

[0062] Specifically, step S104 also includes:

[0063] The library file configuration path data undergoes path existence detection, and any non-existent paths are marked. The marked paths can be checked automatically by computer or manually during implementation to ensure the accuracy of the library file configuration path data.

[0064] S105. Based on the simplified library file configuration path data, configure the corresponding library file in the electronic design automation tool.

[0065] Depending on the actual way the electronic design automation tool calls the library files, the deployment process in step S105 may vary. If the automation tool has never loaded library files before, then the simplified library file configuration path data described in this embodiment of the invention can be used to load the library files one by one according to the path to complete the configuration.

[0066] In a possible implementation, if the electronic design automation tool has a configuration path file for previously loaded library files, then in this case, step S105 further includes:

[0067] Obtain the current library file configuration path file of the electronic design automation tool, and replace the corresponding library file path information in the library file configuration path file according to the simplified library file configuration path data.

[0068] It is understood that, since this embodiment of the invention only changes the configuration path of the library file and does not affect the actual storage location of the library file, the electronic design automation tool should be able to correctly load the original library file after the path replacement, ensuring the availability of its various functional modules. Furthermore, since the simplified library file configuration path data is created based on the specific type of the library file, when a library file path change is required, only the corresponding path entries in the simplified library file configuration path data need to be changed simultaneously. This allows for a unified loading method to change the loading information of all functional modules for the library file, without needing to modify each functional module separately. This design improves the configuration efficiency of the electronic design automation tool.

[0069] The beneficial effect achieved by this invention lies in proposing an electronic design automation tool configuration method that can adaptively configure library files. This method analyzes the set of functional modules and requirements in the tool, summarizes and deduplicates the configuration paths of the library files, and can quickly deploy the library files by unifying or replacing the configuration, while ensuring the accuracy of the configuration and reducing the configuration time of the library files, thereby improving the configuration efficiency of electronic design automation tools.
