If ModelSim-Altera is not installed, you must select Quartus II. Using the Popup Menu to Add Signals to Wave Window. To use ModelSim as the simulator, ModelSim-Altera must be installed. It includes templates for VHDL modules, testbenches, and ModelSim DO scripts. The simulator can be specied by selecting Simulation ¨ Options. VHDL by VHDLwhiz is a fork of the puorc.awesome-vhdl plugin with altered snippets that conform to the VHDLwhiz coding style.

in the dialog which opens in the Visibility tab check the "Apply the full visibility to all modules (full debug mode)". The Simulation Waveform Editor is able to use either ModelSim or Quartus II Simulator to simulate the circuit using the drawn waveforms.
