Batch matching method for USB ports of on-line FPGA experimental equipment

The invention discloses a batch matching method for USB ports of on-line FPGA experimental equipment, which solves the problem that a remote server terminal under an on-line experimental platform cannot acquire a specific corresponding relationship between a USB downloader of an FPGA in a computer equipment manager and the FPGA experimental equipment, and can add the FPGA experimental equipment with codes to the experimental platform without limitation. The remote server terminal can automatically identify the matching relationship between the FPGA experimental equipment and the port, and has good expansibility. A non-configured Flash chip is externally hung on an FPGA chip of a local experimental development board, the Flash chip can store device codes and verification information through coded bit stream files, the bit stream files of different codes are stored at a remote server side, the bit stream files of different codes can be selected from the remote server side and downloaded to a local pc terminal,
