[0065] The present invention obtains table information of multiple tabs, converts the table information into a JSON file, generates an RTL for each module register, and integrates the RTL for each module register, which is conducive to generating the RTL and other related files integrating multiple module registers at one time, thereby improving the efficiency of generating multiple module register related files from multiple tab information.

[0066] The present invention provides a register module generation method based on multi-page excel, such as Figure 1 As shown, the following steps are included:

[0067] S10, obtain excel table information;

[0068] S20, generate a json file based on the excel table information;

[0069] S30, generate the rtl of each module register according to the json file;

[0070] S40, integrating the RTL of each module register;

[0071] The Excel spreadsheet information includes multiple tabs, and one tab includes information of all registers in a module.

[0072] It should be noted that the Excel table is a register table, and its information includes the information of each tab, recording the information of multiple register modules. RTL is the register transfer level, which is a method of describing hardware behavior, describing how registers store data and the data flow between registers, etc. When generating a register module, first extract the information of each tab according to the Excel table, and independently generate the RTL of each register module. The RTL of each register module includes the RTL of multiple registers. The RTL of each register module is integrated to generate the RTL of multiple registers at one time.

[0073] In this embodiment, by obtaining table information of multiple tabs, converting the table information into a json file, generating the rtl of each module register, and integrating the rtl of each module register, it is beneficial to generate the rtl and other related files integrating multiple module registers at one time, thereby improving the efficiency of generating multiple module register related files from multi-tab information.

[0074] In some embodiments, step S30 generates the rtl of each module register according to the json file, such as Figure 2 As shown, the following steps are included:

[0075] S301, generating a register user manual for each module register according to the json file;

[0076] S303, generating ralf of each module register according to the json file;

[0077] S305, generating the code of each module register according to the json file, and instantiating the common components of the register;

[0078] S307, generating a macro definition file for each module register according to the json file.

[0079] It should be noted that when generating a register module, the register description file, i.e., the json file, is used as a basis to generate the rtl and other related files of the module register through the script. The related files include the register user manual, the ralf of the module register, and the macro definition file of the module register. ralf is the verification file of the register verification model, which verifies the read and write behavior and environment of the register. The rtl of each module register can be generated through the reg_gen.py script.

[0080] In this embodiment, by running the generation script, the rtl of each module register is generated according to the json file, which is conducive to the integrated generation of multiple module registers.

[0081] In some embodiments, in step S303, after generating the ralf of each module register according to the json file, such as Figure 2 As shown, the following steps are also included:

[0082] S304, modifying the format of ralf generated by each module register, and managing the ralf of each module register.

[0083] In some embodiments, step S304 modifies the format of the ralf generated by each module register and manages the ralf of each module register, such as Figure 3 As shown, the following steps are included:

[0084] S3041, obtain the ralf generation script;

[0085] S3042, modify the ralf generation script to generate system ralf;

[0086] S3043, the system ralf refers to the ralf of each module register, and the ralf of each module register is managed.

[0087] It should be noted that for the integration of register verification files, the format of ralf file generation needs to be modified. The specific operation is to first generate the ralf of each module register through the reg_gen.py script, modify the ralf.py script nested in the reg_gen.py script, i.e., the ralf generation script, to generate the system.ralf file, i.e., the system ralf, and reference the ralf of each module register in the system.ralf. After that, the system ralf can be converted into register model code through the verification tool.

[0088] In this embodiment, by modifying the RALF generation script, the generated RALF file references the RALF of each module register, which is beneficial to the RALF integration of the multi-module register verification model.

[0089] In some embodiments, step S40 integrates the rtl of each module register, such as Figure 4 As shown, the following steps are included:

[0090] S401, instantiate each module register to the top-level module;

[0091] S402, connecting the configuration bus of each module register to the configuration bus of the top-level module;

[0092] S403, storing the rtl of each module register in the same directory;

[0093] S404, generating a file list pointing to the rtl of each module register, and managing the rtl of each module register.

[0094] It should be noted that the rtl of each module register can be integrated through the integration script reg_release.py. Specifically, multiple module registers are instantiated into a top-level file reg_top.v, and the configuration bus of each module register is connected to the configuration bus of the top-level module. After that, all rtl and reg_top.v can be copied to a folder, and finally a filelist file is generated, which points to all rtl to complete the integration.

[0095] In this embodiment, by instantiating the module register to the top-level module and managing the module register and the RTL of the top-level module through a file list, it is beneficial to generate RTL and related files at one time, and all files are generated synchronously when the Excel table information is iterated, thereby improving work efficiency.

[0096] In some embodiments, step S402 connects the configuration bus of each module register to the configuration bus of the top module, such as Figure 5 As shown, the following steps are included:

[0097] S4021, obtaining the input information and output information of the rtl of each module register;

[0098] S4022, obtaining configuration bus information of the top-level module;

[0099] S4023, set address mapping according to the input information of the rtl of each module register, the output information of the rtl of each module register and the configuration bus information of the top-level module, and generate a selection signal.

[0100] It should be noted that by running the integrated script reg_release.py, the input and output information of the rtl of all module registers is extracted, and the address mapping of the configuration bus signal of reg_top, i.e. the top-level module, and the relevant input and output setting of the module register domain is printed, and the selection signals of different modules are processed according to the address mapping to complete the connection between the configuration bus of the register and the configuration bus of the top-level module.

[0101] In some embodiments, step S20, before generating a json file based on the excel table information, such as Figure 6 As shown, it also includes:

[0102] S11, check the fields of the Excel table information;

[0103] S12, judging whether the Excel table information passes the field check;

[0104] S13, when the Excel table information passes the field check, a JSON file is generated according to the Excel table information;

[0105] S14, when the Excel table information does not pass the field check, stop generating the register module.

[0106] It should be noted that field checking includes defining the register model, generating the register abstraction layer, writing the verification environment, writing test cases, formal verification and simulation verification, which involves the definition and generation of registers, the construction of the test environment and the writing of test cases. When the register information passes the field check, it means that the register can work under various conditions, and when the register information does not pass the field check, the register information needs to be reviewed again.

[0107] In this embodiment, by performing field check on the Excel table information, it is ensured that the generated register module can work as expected, thereby improving the correctness of the register module generation.

[0108] The present invention provides a register module generation system based on multi-page tab Excel, and applies the above-mentioned register module generation method based on multi-page tab Excel, such as Figure 7 As shown, including:

[0109] Information acquisition module, used to obtain Excel table information;

[0110] The field check module is used to check the fields of the Excel table information and determine whether the Excel table information passes the field check;

[0111] JSON file generation module, used to generate JSON files based on Excel table information;

[0113] RTL file integration module, used to integrate the RTL of each module register;

[0114] The Excel spreadsheet information includes multiple tabs, and one tab includes information of all registers in a module.

[0115] In this embodiment, by obtaining table information of multiple tabs, converting the table information into a json file, generating the rtl of each module register, and integrating the rtl of each module register, it is beneficial to generate the rtl and other related files integrating multiple module registers at one time, thereby improving the efficiency of generating multiple module register related files from multi-tab information.
