Virtual simulation test method based on FPGA embedded processor

Abstract

The invention discloses a virtual simulation test method based on an FPGA embedded processor, which comprises the following steps: 1, checking a software development environment of a tested FPGA, and if MicroBlaze series development is used, executing a step 2; if the tested FPGA software is developed by using the Zynp series, executing the step 3; step 2, file connection and conversion: converting a C language in the tested FPGA software into an executable file; reading the executable file, and carrying out simulation testing; and step 3, compiling a bus BFM file, replacing the original hardcore IP with the BFM file, and calling the BFM file to carry out a simulation test. According to the virtual simulation test method disclosed by the invention, the virtual simulation test of the FPGA embedded processor cooperatively developed by two languages can be realized. Therefore, the correctness and completeness of the design are ensured, errors caused by the design in the subsequent production work are avoided, the economic cost is saved, and the project is ensured to be completed on schedule.
