Waveform simulation generates no output

I installed Quartus Prime Lite 21.1.0.842 and Questa FPGA Starter 21.1.0.842 on Linux Mint 20.2. I wanted to start by simulating a simple "AND2" circuit so created a project for MAX II device famil...

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.

Best Regards,
