No output while simulation using Waveform Editor

I tried simple circuit using not gate as per below and I simulated using waveform editor, but there is no output in simulation. Refer below image, My Quartus Edition: Quartus Prime ...

I have the same problem too:

No output signal comes using "Run Functional/timing Simulation" inside Simulation Waveform Editor.
I tried different simulators (Modelsim/Questa) but even if the process terminates successfully without any error, no output is displayed.

    OK I Found the solution by myself:

    1- Instead of removing the "-novopt" from the simulation options try add it with : -suppress 12110
    (e.g: vsim -suppress 12110 -novopt $ elabcommand )

    2- Control that in the folder "C:\intelFPGA_lite\21.1\questa_fse\intel\verilog\cyclonev" (depending from your device) you have a complete write access.
