Hi,

Thanks for those who replied to my enquiry re "Sweeping Temp within MonteCarlo in HSPICE".
The consensus is that temperature cannot be treated as a normal parameter in Spice thus
MonteCarlo (or other similar analysis) cannot sweep the temp in a user defined distribution
fashion. I think this is a limitation in Hspice that AVANT! should look into in their next
release.

Regards,
