实现时出现如下错误：
[Chipscope 16-302] Could not generate core for dbg_hub. Aborting IP Generation operaion. The current Vivado temporary directory path, ‘E:/E-drive-143921/3601/verilog/V2019d2_3601T3d0_KU_V1_netlist_20180413/V2019d2_3601T3d0_KU_V1_netlist_20180413/KU060_3601.runs/impl_1/.Xil/Vivado-2656-ZSB-A609’, is 159 characters. Errors on the host OS will occur when trying to insert logic for debug core ‘dbg_hub’ when temporary directory paths exceed 146 characters. Please move this Vivado project or the Vivado working directory to a shorter path; alternately consider using the OS subst command to map part of the path to a drive letter.
根据其错误报告，是由于路径的字符数太多了，减少路径字符数后问题解决。
