FPGA Physical Automation Verification Technology Based on VCD Waveform

Abstract

According to the shortcomings of low real-time simulation test and insufficient physical test in the process of Field-Programmable Gate Array (FPGA) software test.. FPGA physical automation verification technology based on Value Change Dump (VCD) waveform is proposed. By compressing and converting VCD waveform data into selfdefined test vectors, the problem of too large input semaphore is solved. The real-time transmission of self-defined test vectors is realized by PCI-E data bus and DMA data sharing, and the real signal injection of FPGA chip under test is completed by data-pin mapping. Finally, the result comparison is automatically completed by collecting the return signal of the FPGA chip. The verification results on the verification platform of the FPGA show that the technology can complete the physical verification of the FPGA chip on the basis of ensuring the adequacy of the test.
