Re: hspice behavioral model from ibis 2.1

Hello Fred:

  I'm sorry, I wasn't very clear in my critisism of SPICE vendors. I was
refering specifically to support for IBIS version 2.1 -- specifically the
V/T curves. I know that Avant! (then Metasoft) and Microsim did do IBIS to
SPICE translators for IBIS v1.1, but either did not go onto 2.1 or dropped
support for V/T curves. I was not aware of any other vendors that supported
IBIS 2.1. If Applied Simualtion does then my appologies, and I stand (most
happely) corrected.

              Regards,
              Stephen Peters
