Questa crashes adding waves to VCD

Hi Adam.

Questa will sometimes crash and disappear when it encounters confusing situations. Try running it all by itself, without calling it from another app. Try loading a simple, totally different HDL project to see if the problem changes.

The symptom you describe, disappearing when you add signals to the wave window, is very common with an incorrect license.

I have not able to replicate the issue due to bandwidth circumstances but here few ways I could think of

1. If you're sure that your lic file is ok, try to place it in a new folder. Call it for example msim.dat in toto folder.

In the environment variables, add the new environment.

example: LM_LICENSE_FILE set to c:\flexlm\license.dat

change it to

c:\toto\msim.dat;c:\flexlm\license.dat

In turn your Questa FSE license will be read first

2. Deleted all files in the Questa FSE project folder, except for the source files and re-compiled

Let me know if this is working
