Abstract: For the actual needs of improving the processor core performance of domestic processors, aiming at the performance defects that may appear in the RTL design of processor cores, this paper proposes a lightweight processor core performance analysis framework based on RTL simulation. The performance analysis framework is designed based on lightweight directional and random tests. Through the rapid simulation of the RTL design of the base processor core (Base Core) and the new generation processor core (New Core), and the comparative analysis of the simulation results, the performance defects that New Core may introduce in the RTL design process are found quickly. Based on the performance analysis framework, combined with actual application scenarios, the test methods and test results are given. The test results show that the performance analysis framework proposed can timely find the performance defects introduced by the new processor core in the RTL design process, and effectively accelerate the development of the domestic processor core.
