I met a fatal error duing runing cadence AMS simulator. The version of ncsim i used is IUS8.1 and the spectre version is MMSIM7.1.
In the end of log file, it appears the following error information
"you have no permission to run spectre circuit simulator".
It is not a licence probelm because i can still run other normal analog simulation with spectre.
what's wrong with my simulator? Thanks a lot if you can give me a hand.
