Laurence:
         Model supports is a little slow from Hyperlynx. I have been waiting
for one year to see when support for IBIS Version 3.2 or later shows up and
so
far haven't see it yet. Definitely ease of use is a plus for Hyperlynx.

         I found building complex netlists for LVDS SCSI simulation using
Hyperlynx preset netlist template is very time comsumption and eventually
you
need a movie projector to see most of the netlist that you create.

         Coupled Lossy transmission lines update will be welcomed as well

Regards,
Michael Chan

Hmm... Why did you eliminate Hyperlynx? I've heard good things about
HLs ease
of use, which may turn out to be more important than feature set. If a
tool's
too hard to use, you may find your other engineers refusing to use it,
or
ignoring the results.

XTK experiences: positive, except for XFX3D tool (which should not be
purchased
until they show you it can do what you need it for). Ease of use was
low when
I first tried XTK, but has improved greatly since Viewlogic introduced
"ePlanner".
Viewlogic bought XTK almost a year ago, so the integration between
Viewdraw and
XTK has greatly improved.
ICX experiences: none. Mentor bought Veribest not too long ago, so
things may
change for the better in their Windows based tool-set.

I'd go with a simplified SI tool, so that your design engineers have a
way of
quickly checking a simple design, along with a more complicated
"simulate the
whole d**n thing, looking for problems" tool for the SI group (one
person,
usually) to use on boards that may be problematic.

Welcome to the group, and beware the Ides of March,
