In order to solve the problem of FPGA configuration failure when the satellite camera is power-on,a FPGA configuration process monitoring system was designed.First,the process and principle of FPGA configuration were analyzed in detail.Then,this paper described the core monitoring circuit in the FPGA configuration monitoring system,the design ideas of software for the monitoring system,code implementation and simulation procedures for monitoring FPGA configuration.Finally,the experiment data were processed by MATLAB software,and thus FPGA device configuration failure rate and failure rate curve were obtained to verify the feasibility and superiority of the design.Experiment results indicate that by using the system the success rate of FPGA configuration is up to 100%.Compared with the traditional methods of FPGA configuration,the new design made configuration success rate increased by 0.041%,can satisfy the satellite camera＇s requirements of high success rate and reliability of configuring the FPGA application.This scheme has been applied to the development of a certain space camera.The application results show that the FPGA configuration monitoring system can monitor timely exception which occurs in the process of FPGA configuration and can analyze the error origins and can configure successfully the FPGA applications when the satellite camera is one-time power-on.
