and S1012, acquiring an information description file from a target storage position corresponding to the access path according to the access path indicated in the general configuration file.

Here, after the general configuration file of the current chip subsystem is acquired, according to the access path indicated in the general configuration file, the information description file may be acquired from the target storage location corresponding to the access path, and the information description file may be stored in the determined dynamic storage, so as to perform the subsequent parsing processing.

Here, by setting the access path corresponding to the information description file in the general configuration file, after the general configuration file is acquired, the information description file can be acquired more quickly according to the access path, transmission of the information description file is not required, and the acquisition process is more convenient.

For S102:

the general configuration file can be analyzed to generate a conditional constraint combination for low power consumption design of the current chip subsystem, wherein the conditional constraint set comprises one or more of the following: global macro variables, design types, tool types, mapping relations of module instantiations, power lists and additional files.

In implementation, the global macro variable may be used to analyze the information description file, for example, a variable corresponding to the macro variable M1 may be set as b in the information description file, and conversely, a corresponding variable is x; further, when finding that the macro variable M1 exists after analyzing the general configuration file, selecting the variable b; in the absence of the macrovariable M1, the variable x is selected. The design type can be used for limiting the output of the design grammar, namely, the template content matched with the design type can be selected from the file template for filling and outputting; the tool type can be used for limiting the output of tool grammar, namely, the template content matched with the tool type can be selected from the file template for filling and outputting.

The mapping relation of module instantiation can be used for solving the situation of instantiation inconsistency among netlists, for example, when different modules are used for power consumption design, names of the same port or the same power domain may be inconsistent, and the mapping relation of module instantiation can solve the problem of instantiation inconsistency. The power supply list may be used to set the operating voltage and range of the power supply. The additional file is used for adding some extra content to the generated power consumption intention file, and the extra content can be content designed by a user according to chip requirements, for example, the additional file can include test content, timing content and the like. Wherein the additional files can be designed according to the needs.

And the information description file can be analyzed to generate power consumption strategy information for low power consumption design of different chip subsystems. The power consumption policy information may include power consumption policy information required by each chip subsystem. Furthermore, when the power consumption intention file corresponding to each chip subsystem is determined, the information description file does not need to be analyzed for many times, resource waste caused by the analysis process of the information description file for many times is avoided, and the file generation efficiency can be improved.

Wherein the power consumption policy information includes one or more of the following information: the method comprises the following steps of power domain declaration information, power domain integration information, port power domain information, power switch information, power mode information, power isolation strategy information, level shift strategy information, power retention strategy information, increment design information and post-processing information.

The integration information of the power domain may include a connection relationship of the power domain, a power connection relationship between the module and the constituent subsystems, and the like. The power domain information of the port includes a power domain corresponding to each port, a power domain type, and the like.

The information of the power modes may include a corresponding switch state of the power domain in each power mode. The information of the power isolation policy, the information of the level shift policy, and the information of the power retention policy can be seen from tables 5, 6, and 7. The incremental design information may be additional information designed by the user according to the chip requirements, which is specifically shown in table 8. The post-processing information may update the defined information on the generated power consumption intention file after the power consumption intention file is generated.

For S103:

here, a file template corresponding to the power consumption intention file may be set in advance. The power consumption intention file may be in a CPF format, a UPF format, or other description format, among others. For example, when the power consumption intention file is in the CPF format, the file template is a file template in the CPF format. When the power consumption intention file is in a UPF format, the file template is in the UPF format. And then filling a file template of the power consumption intention file based on the condition constraint set and the power consumption strategy information to generate the power consumption intention file.

In an alternative embodiment, referring to fig. 2, the populating a file template of the power consumption intention file based on the conditional constraint set and the power consumption policy information to generate the power consumption intention file may include:

s201, determining target power consumption strategy information required by low power consumption design of a current chip subsystem from the power consumption strategy information based on a condition constraint set;

s202, filling a file template of the power consumption intention file based on the condition constraint set and the target power consumption strategy information, and generating the power consumption intention file.

Here, the power consumption policy information may include power consumption policy information required for low power consumption design of different chip subsystems in each design stage, so that when low power consumption design is performed on different chip subsystems in each design stage, power consumption policy information matched with each chip subsystem may be directly determined from the analyzed power consumption policy information, and an information description file does not need to be analyzed for multiple times, thereby improving file generation efficiency, and simultaneously avoiding resource waste caused by analyzing the information description file for multiple times, and saving processing resources.

Because the power consumption policy information includes power consumption policy information required for low power consumption design of each chip subsystem, the target power consumption policy information corresponding to the current chip subsystem needs to be determined from the power consumption policy information according to the condition constraint set. For example, the current design stage corresponding to the current chip subsystem may be determined according to the conditional constraint set, and then the target power consumption policy information required by the current design stage of the current chip subsystem may be selected from the power consumption policy information. And filling a file template based on the condition constraint condition and the target power consumption strategy information to generate a power consumption intention file.

In an alternative embodiment, in S202, based on the conditional constraint set and the target power consumption policy information, populating a file template of the power consumption intention file, and generating the power consumption intention file may include:

s2021, determining template contents to be filled from the file template based on the condition constraint set and the target power consumption strategy information;

s2022, filling template contents by using the target power consumption strategy information;

s2023, generating a power consumption intention file based on the filled template content.

In the method, the file template may include a plurality of template contents, and each template content corresponds to different power consumption policy information and/or conditional constraint combination, so that the template content to be filled may be determined from the file template based on the conditional constraint set and the target power consumption policy information; filling template contents by using the target power consumption strategy information; and then, based on the filled template content, a power consumption intention file is generated, the generation process of the power consumption intention file is simple and convenient, and the efficiency is high.

Here, the file template includes a content set corresponding to each power consumption policy information, and the content set corresponding to each power consumption policy information includes template contents corresponding to different design types, different tool types, or the like. Therefore, the template content matched with the conditional constraint set and the target power consumption strategy information can be selected from the file template to be used as the template content to be filled. For example, the template content one may correspond to the tool type of the icc in the power domain, the template content two may correspond to the tool type of the vcs in the power domain, the template content three may correspond to the tool type of the icc in the power switch, and the template content four may correspond to the tool type of the vcs in the power switch, so that the target power consumption policy information includes the power domain, and when the condition constraint set includes the tool type of the icc, the template content one may be used as the template content to be filled.

In implementation, the target power consumption policy information may be used to fill template contents, for example, module names in the template contents are: xxx, the module name in the target power consumption policy information is: and the module I can be filled into the determined template content to generate the filled template content.

In an alternative embodiment, in S2022, populating the template content with the target power consumption policy information may include:

firstly, performing target operation processing on target power consumption strategy information based on template content to generate processed target power consumption strategy information; the target operation processing comprises at least one of data format conversion, data statistics and data calculation;

and step two, filling template contents by using the processed target power consumption strategy information.

Here, the target power consumption policy information may be subjected to the target operation processing based on the template content, for example, when the template content is xx-xx, the target power consumption policy information may be subjected to data format conversion to be converted into xx-xx format, and the processed target power consumption policy information may be filled into the template content to generate the filled template content. Alternatively, the template content includes: a maximum value; a conventional value; and the minimum value can be subjected to data statistics on the target power consumption strategy information, the maximum value of the voltage, the conventional value of the voltage and the minimum value of the voltage are determined, and the maximum value, the conventional value and the minimum value are filled into the template content to generate the filled template content. Or, data calculation may be performed on the target power consumption policy information according to the template content, for example, input and output of the power domain are determined by calculation, and the template content is filled according to the calculation result.

And finally, generating a power consumption intention file according to the filled template content. For example, the filled template content may be stored in an initialization file to generate a power consumption intention file.

In an alternative embodiment, after generating the power consumption intent file, the method further comprises: and updating the power consumption intention file in response to the updated information of the user aiming at the power consumption intention file.

Here, the user may design corresponding update information for the power consumption intention file, for example, the update information may be information for performing a refinement process on the power consumption intention file, so the power consumption intention file may be updated in response to the update information for the power consumption intention file.

The power consumption intention file can be updated in response to the updating information of the user aiming at the power consumption intention file after the power consumption intention file is generated, so that the power consumption intention file can be flexibly modified to be suitable for different chip design requirements, and the diversity and the flexibility of file generation are improved.
