基于USB虚拟技术的FPGA远程片内调试方法实现

Realization of a FPGA remote on-chip debugging method based on USB virtual technology

为了方便FPGA调试,针对Xilinx公司的FPGA提出了一种远程片内调试方法。该方法主要分调试计算机端和测试板卡端两部分的实现。调试计算机端开发上层应用软件,创建虚拟USB设备;测试板卡端以ARM为核心,具有网络和USB主机功能,并完成USB到JTAG转换,最终实现调试计算机上通过网络进行远程调试。

A remote on-chip debugging method for the FPGA of Xilinx is proposed to facilitate the FPGA debugging. This method mainly consists of the PC and the test board. The high-level application software is developed on the PC with the USB virtual device created. The test board with the ARM as its core has the functions of the network and the USB host,and completes the USB-to-JTAG conversion. Finally,the remote debugging is realized via the Ethernet.
