Abstract: Functional test is an essential step in integrated circuit testing, and test vector is the main carrier of functional test. Efficiently and accurately generating functional test vector is the key of testing efficiency and cost. In view of the problems of low efficiency and insufficient redundant comparison in the existing functional test vector generation method based on simulation, this paper proposes a software-based and configurable functional test vector generation and verification system. By utilizing configuration files and test programs, initiatively configure the testing stimuli and response outputs for each step, automatically convert the testing program to the testing port to form stimuli, and assemble all test vector sequences from top to bottom, greatly reducing test vector generation time. Simultaneously generate a reverse self-check verification testbench, using the test stimuli in the vector as the simulation input, comparing the real output of the simulation with the configuration response one by one, and reporting the mismatch points to verify the correctness of the vector, iteratively generating accurate functional test vector
