Isaac,
The Questa-Sim software requires a free license. Return to the Quartus Prime Lite download page and scroll down to the section labeled Additional Resources. You will see a bullet called "Request a License from the..."
Now, with my students, I found we don't actually have to do that process. Instead, we have this workflow on Microsoft Windows:
- Use Quartus --> Tools --> License Setup --> Get No Cost Licenses
- After acquiring a license file, a confirmation dialog will appear with the pathname of the file. Mouse highlight and copy that path name.
- Ensure Use LM_LICENSE_FILE_variable is checked in the same dialog box
- Open the Command Prompt application.
- In Command Prompt: setx LM_LICENSE_FILE <<paste in path>>
- Reboot computer
- Use Quartus --> Tools --> License Setup
- Ensure the Use LM_LICENSE_FILE checkbox is checked. It should be prepopulated with your path name now.
