Hope it helps.
Hi AmirSina,
Modelsim version: Prime lite 17.1.
Quartus version: Prime Lite 21.1.0.842 and Questa FPGA Starter 21.1.0.842
1. Make sure ModelSim path is correct.
2. Make sure directories for Waveform.vwf and Waveform.vwf.vt are correct.
3. After above steps if still error, click 'Restore Defaults' button.
4. Finally, press "Run Functional Simulation" and result as below.
Hope it helps.
Best Regards,
Sheng

I didn't install any version of ModelSim as I read in the download page that ModelSim is replaced with Questa FPGA.
All paths in Simulation Options are correct, just I removed "-novopt" from 5th line of ModelSim Script as it caused error.
The strange thing is Timing Simulation shows the result correctly, however Functional simulation shows unknown output.

Hi AmirSina,
I see. So "-novopt" should not be removed in order for both Timing Simulation and Functional simulation to run properly.

But when I do not remove -novopt this error happens:
I read somewhere that I should replace it with "+acc". but the result of functional simulation is still unknown.
