    You make the AC_meas_tb as the testbench. Can you check inside the AC_meas_tb.v files, what is your module name there? currently, the tools are complaining the testbench issue.

Here is what I noticed.

1) When I start ModelSim from Quartus I get an error. Next, with the CD commands, I go to the msim_setup.tcl file, execute the source and ld commands. The simulation starts. Restarting the simulation fails with the above error.

2) When I start ModelSim from the Windows START menu, with the CD commands I go to the msim_setup.tcl file, I execute the source and ld commands, the simulation does not start, but ends with the same error as when restarting.

That is, the simulation only works when starting ModelSim from Quartus and then writing commands on its command line.

Why does the simulation not work when starting ModelSim from the START menu of Windows and how to restart the simulation all the same without reopening ModelSim?
