Abstract: With the development of processor architecture, high-performance heterogeneous multi-core processors are emerging. Since the design of high-performance heterogeneous multi-core processor is very complex, in order to reduce the design risk, shorten the verification cycle, carry out software development in advance, reproduce the post-silicon problems, we usually need to build a prototype verification platform of field programmable gate array (FPGA), and based on the FPGA platform to carry out a variety of software and hardware verification and debugging work with different functions. This paper presents a method of debugging and verifying heterogeneous multi-core high-performance processor based on homogeneous FPGA platform which effectively utilizes the architecture characteristics of heterogeneous multi-core processor and the symmetry characteristics of homogeneous FPGA platform, divides FPGA by hierarchical top down method, builds the platform from bottom to up. The combination of speed bridge, adaptive delay adjustment, embedded virtual logic analyzer and other technologies can quickly complete the FPGA platform bring-up and deployment. The proposed multi-core complementary, inter-core replacement simulation method with debug SHELL can verify the target high-performance heterogeneous multi-core processor quickly and completely. Through the FPGA prototyping platform, we have successfully completed the pre-silicon verification，software hardware co-development and testing, post-silicon bug reproduce and also provided a fast hardware platform for the next generation processor’s architecture design.
