Modelsim Doesnt include submodules

Hey everyone,

I have an issue where When I compile to generate waveforms, modelsim launches but doesnt compile or carry over any of my submodules.

Is there a setting that ive missed? I didn't play with any custom configurations, everything is for the most part plug and play.

I didn't generate a new QSYS file using the platform designer yet, could that be the reason? I'm eager to learn so feel free to go into the weeds.

Steps I do to compile:

1. Set the top module in project to "Top-level Entity'

2. instantiate my test bench in assignments -> settings -> EDA tool settings -> Native link settings -> Compile testbench

3. Start analysis and synthesis

4. Compile

Tool names:

Quartus prime lite edition 18.1

Ive attatched screenshots of the hierarchy that I see in Quartus and ModelSim below:

    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.

    Compilation options in Quartus are for synthesizing the design into hardware, not simulating the design in a simulation tool. There's a difference between compiling in Quartus (for synthesizing into hardware) vs. a simulation tool (for simulating the design).

    Compile button is for synthesizing flow meanwhile simulation is under simulation tool e.g. typically modelsim.

    Compile button does not include simulation which is expected.
