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.
