Modelsim Doesnt include submodules

for those who may read this in the future, I found two methods to solve it.

A. (manual and incorrect way IMO)

1. In Quartus toolbar, Processing -> Start -> "Start analysis and synthesis"
2. In Quartus toolbar, Processing -> Start ->"compile"
3. Once Modelsim launches, manually add/compile each submodule you need
   • In the toolbar compile -> compile the files in this order: submodules -> top module -> testbench
4. In Modelsim toolbar, simulate -> start simulation -> select your desired testbench file
5. In Modelsim toolbar, simulate -> Run -> Run-all

B. (correct and fast way)

1. in Quartus, click "Start analysis and synthesis"
2. in Quartus toolbar, Tools -> Run Simulation Tools -> RTL Simulation
3. Modelsim **should** now launch with all the files

Honestly I cant explain why just clicking "Compile" doesn't launch Modelsim with the included submodules

I'm open to hearing any feedback and if anyone has any other suggestions.
