  In order to solve the problem of FPGA configuration failure after the Satellite TDI CCD camera power-up,a FPGA configuration process monitoring system was designed.First,this paper analyzes the process and principle of FPGA configuration deeply.Then,this paper describes 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.In order to verify the feasibility and superiority of the design,MATLAB is used to draw FPGA device configuration failure rate and failure rate curve.Experiment results indicate that the FPGA configuration successful rate is up t0 100 % after using this system.Compared with the traditional methods of FPGA configuration,the new design made configuration success rate increase by 0.0333 %.It can satisfy the Satellite TDI CCD camera requirements of high success rate and reliability in configuring the FPGA application.This scheme has been applied in development of a certain space TDI CCD camera.The application results show that the 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 after the satellite camera one-time power-up.
