解决方法

管理员权限运行cmd，查看端口占用，命令如下：

点击查看代码

netsh int ip show excludedportrange protocol=tcp

vivado需要用到的端口是3121，Windows系统保留了部分端口不允许应用使用，所以要打开这个端口。

运行下面的命令：

点击查看代码

net stop winnat
netsh int ip add excludedportrange protocol=tcp numberofports=3 startport=3000
netsh int ip add excludedportrange protocol=tcp numberofports=1 startport=3121
net start winnat

问题解决喽！
