Field Programmable Gate Array Configuration Monitoring Technology for Space-Based Systems

In order to solve the problem of field programmable gate array (FPGA) configuration failure after the Satellite TDI CCD camera power-up, a FPGA configuration process monitoring system was designed. First, this paper describes the core monitoring circuit in the FPGA configuration monitoring system. Then the design ideas of software are proposed for the monitoring system. Finally, the experiments were performed in the monitoring system. Experiment results showed that the proposed FPGA configuration monitoring system can timely monitor exception occurred in FPGA configuration process and can analyze the error origins and can configure successfully the FPGA applications. The FPGA configuration successful rate reaches 98.2 % after using this system. The monitor system can improve the reliability of FPGA configuration and solve the problem of FPGA configuration failure.
