Questa Simulation Not Showing All Needed Variables

I am using Quartus to write my program in and am trying to simulate this in Questa. My program compiles in both applications. When I begin simulation in Questa, some inputs and outputs are missing. T...

Ok, I found the QuestaSim manuals. Looks like I'd need to dig into the scripts that Quartus Prime uses to call Questa Intel FPGA Edition to make that happen. That's pretty ugly. And it seems like calling with -O0 (which is a menu option in Questa and generates a warning about slowness of simulation so I know it's being read) would do this.

Update: in Questa Intel FPGA Edition, you go to Compile/Compile Options, then select the Coverage Tab under "Other Coverage" (the 4th box in 21.1), is an option "Enable Finish State Machine Coverage (+cover f)". If you select that, then hop out of questa and back to quartus and restart questa - yes I'm sure there is a quicker way to do that - then the process in https://nandland.com/view-variables-in-modelsim-waveform/ works - the state, which is a variable, shows up.

Thanks for the help.
