Questa always return X state on output
- 3 years ago
I think it might be the Questa tool issue. I was using Modelsim previously.
Could you try to use Modelsim Intel FPGA edition instead of Questa and see if the issue persists?

You may refer to the User Guide below to set up the Nativelink environment.
Picking up from where you are left, you may generate the testbench in the simulation waveform editor or write your own testbench.
Then set up the testbench in the User Guide step4, Assignment > Setting > Simulation. Turn on Compile test bench. Click Test Benches to add testbench. Specify the testbench name and the top level module in testbench.
Once set up complete, go to Tools> Run simulation tools > Run RTL simulation.
Questa Intel FPGA Edition software should pop up and simulate the result.
