Problem while launching ModelSim simulation from Quartus

[Altera_Forum]

Hello, 

 I'm newbie in Quartus and am starting to learn Quartus design flow. Certain documents I've found on the web, mention that one can run ModelSim simulation from Quartus. Unfortunately it didn't work properly. Here is my setup: 

• Parent module: module_parent.vhd 
• Child module: module_child.vhd 
• Testbench: tb.vhd (not included in the design, but specified in Settings/EDA Tool Settings/Simulation/Compile Test Bench) 

  When I launch ModelSim, only parent module (module_parent) appears in the work library, not module_child, neither tb. Here is fragment of the Transcript window of ModelSim:  Error (suppressible): {path_to_module_parent(line_number_where_module_child_is_instantiated)} : (vcom-1195) Cannot find expanded name : "work.module_child" Error: {path_to_module_parent(line_number_where_module_child_is_instantiated)} : Unknown expanded name.  Thanks in advance.  Pavel

You may find it easier just to drive modelsim yourself: 

 from the modelsim transcript window:   cd <your_working_folder> vlib work vcom module_child.vhd vcom module_parent.vhd vcom tb.tv vsim tb run 10 us restart -f

Thanks, 

 It works. But is it the only way to launch ModelSim simulation from Quartus ? Is it possible to create some scenario to accelerate the things ?  Another curious detail: after simulation launched, I didn't see signals mapped to outputs ... quite strange.

I've found found the reason why output-mapped signals aren't shown - when I uncheck "Enable Optimisation" in ModelSim simulation setup, it becomes Ok. 

Try to find corresponding option for vsim ... there's too many of them. There is -vopt that enable optimization, but I didn't find any option to disable it. Can it be disabled only via ModelSim simulation options ?

Finally I've found it: 

 -novopt

ModelSim launches, compile all 3 entities and starts simulation ?

I've recreated project and now it's Ok, i.e. I can launch ModelSim directly from Quartus and ModelSim correctly compiles both entities and runs simulation. 

Probably there was something wrong with my previous setup.

you can add a do script in the simulation settings somewhere in (i think it is) project->assignments and settings.
