Abstract: As the field programmable gate array (FPGA) scales to more than 10 million gates, the depth of the configuration vector is getting larger and larger, and over 95% of the FPGA manufacturing test time is used to load the test configuration bit stream. In order to realize the fast configuration test of FPGA, a quick test configuration and implementation method of FPGA is proposed. Using the V93000 test system, the test time of the circuit configuration bit stream is optimized by loading 4 rows of configuration vectors in one cycle (is 4X configuration).The Xilinx Virtex-7 series FPGA-XC7VX485T was used as an example to verify the test. The test data shows that compared with the general configuration method, the FPGA single configuration time is reduced by 74.1% in the 4X configuration mode, which solves the contradiction between data configuration and test time in the FPGA test.
