Error about library path of Simulation Waveform Editor

The following instructions are for users who have the Mentor Graphics ModelSim DE 10.5c version installed (Note this is NOT the free Altera version).

The instructions should apply if you have other versions of ModelSim and/or Questa. Also, this was tested with Quartus Prime 16.0 version

1. Make sure to specify the ModelSim simulator path under "Tools -> Options -> EDA Tools Options"

2. Compile the simulation library for ModelSim using "Tools -> Launch EDA Simulation Library Compiler" and specify settings...

3. Copy the "modelsim.ini" file to the "..\simulation\qsim" directory

4. Add under the "[Library]" section the followings:

[Library]

... blah... blah... blah...

cyclones_ver = C:/{Path_to_compiled_ModelSim_Simulation_library}/cyclonev_ver

altera_ver = C:/{same as above}/altera_ver

... (add more here)...

Note that the above paths use "forward" slash (from Windows 10) and not "backward" slash. Also the path is from step 2 above

Once you do this the simulation will run in the Native Quartus Prime environment. You can also take the *.do file and the test bench and run stand alone in Modelsim outside of Quartus.
