Network-based multi-FPGA debugging system and method

The invention relates to a network-based multi-FPGA (Field Programmable Gate Array) debugging system, which comprises a PC (Personal Computer) end, server software, a network switch and a plurality of FPGA boards with network ports, according to the method, a traditional field debugging method for the target FPGA board system is networked, so that debugging personnel can remotely debug and maintain the target FPGA board-level system through the Internet, the development and debugging efficiency is improved, and the maintenance cost is reduced. Program programming and debugging are carried out by adopting a network cable or an optical fiber, the limitation of the length of a JTAG cable is broken through, the JTAG cable needs to be connected with a PC, a special working scene can be applicable only by connecting a network and a network switch, the method is simple and low in maintenance cost, point-to-point debugging and analysis are supported, and many-to-many batch debugging and analysis are also supported.
