I am having difficulty installing a Questa License. I currently have a license (trial, but plan on purchasing a real license once things are setup), for Quartus . The Quartus trial license allows me to compile and download to the MitySOM devkit I have. However, when I try to run the simulator, or the vsim I get this error message:
C:\intelFPGA\23.1std\questa_fe\win64>vsim
Unable to checkout a license. Make sure your license file environment variable (SALT_LICENSE_SERVER, MGLS_LICENSE_FILE, LM_LICENSE_FILE)
is set correctly and then run 'lmutil lmdiag' to diagnose the problem.
Unable to checkout a license. Vsim is closing.
** Error: Invalid license environment. Application closing.
when I run lmutil lmdiag, it seems everything is ok. I have tried with multiple licenses as I have an ethernet mac, a wifi mac, and bluetooth mac on this laptop.
C:\intelFPGA\23.1std\questa_fe\win64>lmutil lmdiag

Hi,
Make sure you have follow the steps in this document https://www.intel.com/content/www/us/en/docs/programmable/683472/22-1/and-software-license.html:
On Windows System
- Go to This PC, right-click, and select Properties.
- Click Advanced System Setting.
- In the Advanced tab, select Environment Variable.
- Under System variables, create a new variable with the name as LM_LICENSE_FILE and value as <license.dat file path>.
- Click OK and restart the Questa* 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%
On Linux System
Run one of the following commands in a command prompt window:
export LM_LICENSE_FILE=<path to license>:$LM_LICENSE_FILE
setenv LM_LICENSE_FILE "<path_to_license_file>"

Hi,
I test from my side without problem. Could you try to re-generate the questa Starter edition license?
Also, try to use command setx LM_LICENSE_FILE <path_to_license_file>;%LM_LICENSE_FILE%
Thanks,
Regards,
Sheng

Ok,
I have tried your suggestions and still get the same results.
I have two projects one from the intel site as a sample application.
https://www.intel.com/content/www/us/en/docs/programmable/703090/21-1/open-the-example-design.html
When I run the simulator on this one I get this dialog.
I also have another project from the client we are working with (which I can not give much detail for NDA reasons), but when I run the simulator on this project I get this dialog (not sure if this is pre or post the license file).
This is how I start the simulator, maybe I am just doing something wrong ?
Thanks,
Chris

Hi,
I know your problem. You're using questa_fe, please use questa_fse (starter edition) when installing. I think you're using this license
Questa*-Intel® FPGA Starter Edition (License: SW-QUESTA) |
---|
The trial license only works for starter edition.
Thanks,
Regards,
Sheng

At this point we can close this one. I will open other tickets up as necessary.
Thank you.
