Abstract: Existing CPU verification platforms are mostly based on instruction code matching technology to build verification platforms. This method has a long development cycle and high debugging difficulty. In the design of CPU chips, efficient and complete functional verification has become an important basis for CPU reliability. Aiming at the verification requirements of a 32-bit CPU chip, a highly efficient and reconfigurable CPU verification platform is proposed, and the design and implementation of the verification platform are completed. The verification platform makes full use of SystemVerilog's string matching technology, integrates verification testcase generation components, reference model components, monitoring components and result comparison components, and uses scripting language to automatically complete batch verification. Compared with the existing CPU verification platform, the development and debugging time of this platform is short, and the modular structure is easy to reuse and transplant. At present, the platform has completed the collection of code coverage and successfully verified the functional correctness of the independently designed CPU.
