Abstract: With the rapid development ofthe design process,the size of the SRAM-type FPGA is getting bigger and bigger,putting higher requirements on the storage capacityand the configuration speed of the configuration chip.In this paper,based on the SRAM-type FPGA,using high-capacity FLASH and BPI interface,and the soft core of JTAG interface to BPI interface through FPGA instantiation instead of the JTAG module of traditional configuration chip,the design of configure chip based on SRAM-type FPGA have been completed.This design has realized the simple design structure,small chip area,storage capacity,speed,compatibility.The feasibility and correctness of the design method is proved through the analysis of corresponding digital simulation waveform and FPGAprototype verification.
