Hi,

QuestaSim either uses LM_LICENSE_FILE or SALT_LICENSE_SERVER. Don't get confused by the key name, SERVER can also be a license file. A special point that I didn't yet found clearly documented is that if you have other Mentor/Siemens tools installed on your PC, LM_LICENSE_FILE won't work although it's still recognized by lmdiag, need to use SALT_LICENSE_SERVER for questa license.

SALT_LICENSE_SERVER can have multiple entries separated by ;

The questa license entry is mandatory to run QuestaSim.

Regards

Frank

    Hi Frank,

    thanks a lot for your reply!

    I tried to set the SALT_LICENSE_SERVER again, as I did so many times before. This time though, I could start Questa without any error. I still do have ModelSim 10.5 installed. I even could enable all enviroment variables related to Quartus Prime 16.1 and Questa still works (even after restart!).

    I also checked Windows Update, there was no update. But I got updates to Microsoft's Defender and HP Wolf Security this morning.

    So I'm left confused, what my initial problem may have caused.

    But I'm happy now.

    Thank you for your assistance!


    Best Regards,

    Thomas
