Abstract: Compared with anti-fuse configuration chips and erasable programmable read only memory (EPROM) type configuration chips, Flash-based FPGA configuration chips have better features such as non-volatility, low power consumption, high security, and multi-programmable. A Flash-based FPGA configuration chip with memory built-in self-test (MBIST) function is designed. A more comprehensive testing algorithm is proposed based on March C?, which can effectively improve the test fault coverage and validate the accuracy of the test results by itself, so that the accuracy of the Flash function can be checked quickly and effectively. Since Flash is non-volatile and highly integrated, and the design has MBIST function, so this configuration chip can meet complex industry scenarios and a wide range of application requirements.
