    Hi,


    Need to specify the simulator LM_LICENSE_FILE path check this document link https://www.intel.com/content/www/us/en/docs/programmable/683472/23-3/faq.html (page 47):

    On Windows System

    1. Go to This PC, right-click, and select Properties.

    2. Click Advanced System Setting.

    3. In the Advanced tab, select Environment Variable.

    4. Under System variables, create a new variable with the name asLM_LICENSE_FILE and value as <license.dat file path>.

    5. Click OK and restart the Questa*-Intel FPGA Edition software.

    Alternatively, open a command prompt and run the following command to set up the LM_LICENSE_FILE environment variable:

    setx LM_LICENSE_FILE <path_to_license_file>;%LM_LICENSE_FILE%

    For example: setx LM_LICENSE_FILE C:\intelFPGA \license.dat;%LM_LICENSE_FILE%


    Thanks,

    Regards,

    Sheng

Hi Drew,


There're some bug with the warning message. I'll report this to internal team.


Btw, you can workaround by ignoring the warning message. After specifying the Executable location path as ../questa_fse/win64 and Output directory path, click Start Compilation. If see this message Specify the simulation tool executable location. pop up, click the three dots beside the Executable location tab and specify the path again then Start Compilation. If still see the same message Specify the simulation tool executable location. pop up again, repeat the steps. Finally after 2-3 trials, you would be able to Start Compilation.


Thanks,

Best Regards,

Sheng

    Hello,

    Thank you for reporting it. It is a weird bug.

    I have tried your method and it did not work. I did it 6 times and I still got the same result. Anything else I can try?

    Thank you,

    Drew
