Hi everyone, it happened to me that by chance I interrupted ModelSim not
properly (to be honest I cannot say what happened) and on the next start
it showed me this message:

Warning: (vsim-WLF-5000) Log file vsim.wlf currently in use

I tried to remove the file, thinking (uncorrectly I suppose) that the
program would have generate a new one, but it didn't work. I found on
some forums that is a problem of license but I have a Libero web
license, so if it was so I would have had problems with Libero and
Synplify as well (they are all under the same license).
Could you please explain me what happened?
Thanks a lot

Al

Just to add more info, I made a new project with Libero, starting
everything from the scratch and only importing the source file. Now it
hangs in a different way and on the bottom raw it shows:

sim:/fe_pinout_tb - Limited Visibility Region

where fe_pinout_tb is my testbench entity name.
Any idea?

Sorry again, apparently this last problem was a matter of the order in
which testbench files where compiled. Fixing this latter it turned back
the first one.
The warning message is always the same:

Warning: (vsim-WLF-5000) Log file vsim.wlf currently in use

Sorry for all these, I'm a bit in a hurry...

Deleting that file (vsim.wlf) works for me. You can ignore the warning
anyway, it will just use another file.

Also you can use vsim -wlf filename to specify another file to use.

Cheers,

I'm very sorry to all of you guys, it has been just a newbie error! I
had a process in the testbench with no wait state and it was hanging
there forever...
Sorry to everyone.

p.s.: nevertheless it keeps giving be that warning, wonder what is that for!
