Use Floating License Servers

I used to just set LM_LICENSE_FILE environment variable to all floating license servers for all EDA tools that I use. It had become unacceptably slow to start and run Matlab with LM_LICENSE_FILE (see this Matlab solution for more information), so I switched to use individual environment variable that each EDA vendor checks for licenses. Things have been working a lot better since I made the change. Below is a list of environment variables that tools I run on a regular basis check for a license. This is mainly for my own reference. Hopefully somebody else may also find it useful.

Mentor Graphics: MGLS_LICENSE_FILE

P.S.: Check AR11630 ( for instructions on how to set up environment variables. My personal favorite tool for setting/editing environment variables is Rapid Environment Editor
