一种基于XVC协议的FPGA调试模块设计

A Design of FPGA Debugging Module Based on XVC Protocol

舰船电子设备通常由多块板卡构成,且设备的内外部环境复杂,许多板卡都放置在密闭的机箱内,因此在舰船上按照传统USB-JTAG模式对板卡上的现场可编程门阵列(FPGA)芯片进行调试时会有很多不方便。设计了一种基于赛灵思虚拟电缆(XVC)协议的点到多点(PTMP)以太网调试模块,通过单个以太网口就能远程调试所有板卡上的FPGA,并支持多人同时调试,有效提升了舰船现场的调试效率。

Shipboard electronic equipment usually consists of multiple boards,and the internal and external environment of the equipment is complex.Many boards are placed in a closed cabinet,so the field programmable gate array(FPGA)chip on the board has a lot of inconvenience when debugging is performed by traditional USB-JTAG mode.This paper designs a point-to-multipoint(PTMP)Ethernet debugging module based on Xilinx visual cable(XVC)protocol,which can remotely debug FPGAs on all boards through a single Ethernet port,and supports simultaneous debugging by multiple people,effectively improves the debugging efficiency at the ship scene.
