“Unable to checkout a viewer license necessary for use of the ModelSim graphical user interface. Vsim is closing.”
当尝试了多次重新安装ModelSim，多次尝试po jie，设置系统环境变量无效后，检查License文件，发现License文件中有本机网卡Mac地址，核对本机Mac地址，发现不一致，解决方案便是，自己在命令行里运行mentorKG工具：
注:your_nic_id是真正的网卡mac地址
MentorKG.exe -h your_nic_id -patch .
这样生成的License文件就正确了，然后即可po jie成功.
