An FPGA Bit-Stream Read Back and Reconfiguration Based Hardware Fault Tolerance Method for Space Applications

In this paper,the FPGA configuration frame format and configuration frame type and distribution in the whole device is analyzed.Based on the analysis,the detail of bit-stream read back fault detection method and reconfiguration fault tolerance method is presented.Finally,a circuit implementation with this paper's fault tolerance method is illustrated.The research contributes to the circuit fault tolerance design method of all satellite subsystems that use SRAM-based FPGAs.
