I downloaded the latest version "git clone ...." I still have the problem. Looks like the time time is not advancing ..
I tried the technique you mentioned and I get the following.. I have attached a zipped vvp file.
vvp -v hub_tb.vvp +DUMPON -lxt
Compiling VVP ...
... VVP file version 0.10.0 (devel) (s20090225-81-g4affc6e)
Compile cleanup...
... Linking
... Removing symbol tables...
The simulator locks up with the attach file. Perhaps there is a race condition (pretty sure there isn't).
Simulates fine with modelsim.
I'm using version 20080905
File was too large to attach, uploaded at
http://FileHost.JustFreeSpace.Com/457hub_tb.vvp
Not sure how long they will keep. If it is gone, send me an email & I will email the file
Thanks & let me know if you need more...
