Description

Technical Field

[0001] This invention relates to the field of communications, and in particular to a method and application for configuring test cases based on the Cosim platform. Background Technology

[0002] In the verification process of network switching chips, it is difficult to simulate and construct some complex network application scenarios under real network protocol conditions at the module level. Therefore, system-level simulation is used to verify whether the operation of multi-module linkage functional blocks meets expectations. In network switching chips, large functional blocks are generally verified for specific network packets or protocols. At this time, co-simulation with the software reference model can not only construct specific test cases to simulate specific network scenarios, but also integrate the software environment in advance to shorten the overall chip development time.

[0003] In large-scale network switching chips, not only do numerous control registers need configuration, but also many tables, such as forwarding tables for controlling forwarding and tables for matching IP and MAC addresses. Moreover, as customer demands for larger tables increase, the size of these internal tables within the chip continues to expand. Cmodel configures test cases through the CPU interface, configuring registers and tables one by one by address. Therefore, the configuration file grows larger as the number of internal registers and tables increases. For example, a typical test case for a switch chip might have over 60,000 CPU access commands, while the Costim platform requires over 20,000 test cases for simulation.

[0004] Currently, scripting tools parse the configuration files used by Cmodel test cases according to the addresses of registers and tables, converting them into backdoor-style configurations recognizable by the Cosim platform, and then configuring them via the backdoor. First, the addresses of all registers and tables used by the chip are parsed. Then, the configurations provided by Cmodel are matched one by one, and the matched configurations are printed to the configuration file used via the backdoor. For smaller chips, this method is efficient because the Cmodel test case configuration files are also small, with fewer registers and tables. However, as chip scale increases, each test case configuration can contain tens of thousands of lines, making the time cost of converting each test case configuration quite high.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a method and application for configuring test cases based on the Costim platform, thereby solving the problem of low efficiency in configuring test cases based on the Costim platform.

[0025] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0026] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0027] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figures 1 to 2 As shown, an embodiment of the present invention describes a method for configuring test cases based on the Costim platform, which includes the following steps.

[0030] In step S101, the chip register and table entry address are parsed and stored in the Cosim database.

[0031] Simulation results on the Cosim platform show that parsing chip register and table entry addresses takes 55 seconds, and matching the test case configuration with these addresses to generate the configuration takes 4 minutes and 30 seconds. This indicates that parsing chip register and table entry addresses is a repetitive process for all test cases. Therefore, in this embodiment, the process of parsing chip register and table entry addresses is extracted and performed only once, generating an intermediate Cosim database, Cosim.db. This database serves as the input for the process of matching the test case configuration with the chip register and table entry addresses to generate the configuration. Thus, 55 seconds can be saved in configuring each test case, which is a considerable time saving for tens of thousands of test cases.

[0032] In step S102, the names of registers and table entries in the Costim database are used as indexes to match the configuration of Cmodel test cases and generate the corresponding configuration files.

[0033] Since a configuration within a specific address range must belong to a particular register or table entry, register and table entry name identifiers are added to the existing Cmodel test case configuration files, which are configured entirely according to address. The Cosim database generated during the parsing of chip register and table entry addresses uses register and table entry names as indexes for data organization. During the process of matching test case configurations with chip register and table entry addresses to generate configurations, it is no longer necessary to match a single configuration across the entire chip's address space; instead, register and table entry names are directly used for indexing, significantly saving matching time. Testing showed that the original test case configuration matching and generation, which took 4 minutes and 30 seconds, can now be completed in just over 8 seconds, greatly improving efficiency.

[0034] The configuration format for test cases is as follows:

[0035] A B C D 03 85949f40 0000004a #RegisterACtl221[274877906944 / 0x4000000000] 03 85c9ba00 00000000 #TableBCtl246[274877906944 / 0x4000000000] 03 85c9ba04 00000000 #TableBCtl246[274877906944 / 0x4000000000]

[0036] Where A represents the chip ID, B represents the chip address, C represents the configuration content, and D is the name of the configuration register and table entry.

[0037] The data format stored in the Cosim database is as follows:

[0038]

[0039]

[0040] When configuring test cases, the corresponding configuration register and table entry names are RegisterACtl and TableBCtl, respectively, according to the configuration format of the test cases. In the Cosim database, RegisterACtl and TableBCtl can be used as indexes to match RegisterName and MemName, which can quickly generate the required backdoor configuration file.

[0041] The method and application for test case configuration based on the Cosim platform according to embodiments of the present invention can separate the original chip register and table entry parsing and implement them separately, avoiding repeated parsing of these common information in different test cases. By adding the Cosim database for address storage and matching of test case configuration, the efficiency of Cosim test case configuration conversion can be improved.

[0042] like Figure 3 As shown, an apparatus for configuring test cases based on the Cosim platform according to a specific embodiment of the present invention is described.

[0043] In an embodiment of the present invention, the device for configuring test cases based on the Cosim platform includes a parsing module 301 and a configuration module 302.

[0044] The parsing module 301 is used to parse the chip registers and table entry addresses and store them in the Cosim database.

[0045] Configuration module 302 is used to match the configuration of Cmodel test cases by using the names of registers and table entries in the Costim database as indexes, and generate the corresponding configuration files.

[0046] The configuration module 302 is also used for: reading the Costim database; parsing the configuration of Cmodel test cases; matching the names of registers and table entries in the configuration in the Costim database; and generating register configurations and table entry configurations.

[0047] Configuration module 302 is also used to configure Cmodel test cases via a backdoor configuration method.

[0048] In this embodiment, the test case configuration includes at least: chip ID, chip address, configuration content, and the names of registers and table entries.
