Design of FPGA remote debugging system based on Internet

Abstract

Due to highly customized feature, once the program of FPGA system is fixed, it is extremely difficult to keep maintenance. The system uses MicroBlaze processor to implement TCP/IP protocol stack, realizes the real-time online update of modules in FPGA system by upgrading files through Internet, and completes remote command injection and data upload for remote debugging. Based on ethernet mode, the system can be separated from the traditional debugging method, realize remote equipment debugging without manual participation on the equipment site, and reduce maintenance costs. The system has the characteristics of reliability, fast configuration, and no need to restart using this method, and can also be used in other directions such as cloud computing and real-time simulation.
