Lynne, the big point of inertia is of course that HSPICE is entrenched
and uses a proprietary encryption standard. Those combined facts
provide Synopsys with a market advantage they would be foolish to
dilute. It is very frustrating to those of us who find HSPICE both
pricey and Spartan compared to alternatives. But Chris is right: the
IC guys have today in HSPICE a tool which gets them through the day and
has an established base throughout the food chain. If a competitor
wants to break into that, IMO they will have to find a way to overcome
the incremental cost of multiple models and model support at the IC
side. That's a tough nut to crack. The danger I see for Synopsys is
that if that nut gets cracked, the creaky aspects of HSPICE could well
cause its market to quickly collapse.
Best Regards,
Steve
