This paper introduces a method of FPGA programmable logic device programming based on SRAM technology, which can automatically program the device during system reset or power-on to effectively solve the problem of volatile power-down of SRAM-based FPGA devices. In view of the current system scale , This paper presents a solution to automatically load multiple FPGAs with a singlechip.1 Hardware Principle nCONFIG Output Device Reset Pin CONFIG_DON
