I am not suere about the installer of Quartus Lite but the installers of the Standard and Pro versions come with both Modelsim Free and Paid; you have to specifically install the Free version. Furthermore, Modelsim Free Edition has a line limit of 10,000; maybe you are running into that limit?

By any chance, is it failing when you re-run it after a successful run? I've had issues with some Modelsim sub-processes not getting properly terminating when running on Linux (which then gives weird behavior when you then re-run).

Thanks for your responses,@HRZ​ @AndyN​ .

 

  • The Modelsim install is the Intel FPGA Starter Edition v10.5b, and the projects are well less than the 10k line limit.
  • It appears to fail at random, with exit code 4.
  • Per the Modelsim user manual, exit code 4 is a license issue.
  • This is consistent with the fatal error that shows up in the transcript.

HI. Yes. I ended up requesting a license and it solved the problem.
