Abstract: This paper builds a FPGA verification and test system for cryptographic chip based on PCIE communication.The system provides the method of FPGA verification before tapeout and test after tapeout for SM234 cryptographic chip.Using FPGA implements logic of the cryptographic chip to verify the chip function and reduce the risk of tapeout.Meanwhile,the system provides a feasible chip test scheme for the post test to cut down the test time.Given the requirement of high-speed data transmission,the system selects the PCIE bus to complete the data transmission between card and computer,improves the efficiency of SM234 cryptographic chip verification and test plan.
