如题，修改之后，verdi起来了。但是vsim还是不行。难道是license，path冲突了?显示的是：
Unable to checkout a license. Make sure your license file environment variable (e.g., LM_LICENSE_FILE)
is set correctly and then run 'lmutil lmdiag' to diagnose the problem.
Unable to checkout a license.Vsim is closing.
** Fatal: Invalid license environment. Application closing.
运行lmutil lmdiag之后显示
[zxji@zxji ~]$ lmutil lmdiag

没有vsim的license文件！（没装ius之前vsim verdi都能正常启动，怎么会没有license）
到底是什么原因啊！困扰了好几天了，，，
