SPECCTRAQuest, now called Allegro PCB SI, has a spice based engine under
it. It supports IBIS models, Macro Models for more complex devices with
pre-emphasis (see post by Ken Willis on SI-LIST on 12/09/03
http://groups.yahoo.com/group/si-list/message/10093) as well as Quad XTK
models.=20
Re "To get the most out it (SQ), you need HSPICE": you only need HSPICE
engine when the models are ENCRYPTED HSPICE models. only HSPICE can
un-encrypt encrypted HSPICE models.=20

Hi Gil,
It really depends on what you what to simulate. I've found that both
tools are very good at what they do.
Hyperlynx is a IBIS simultor and is a fine tool for simulating sub 1G
devices and models however it starts to fall over at the higher speeds
and more complex systems.
SpectraQuest is a very robust tool but to get the most out of it you
need a HSPICE license, pushing the price of the tool up. However I've
used it for simulations up to 10Gbps.
Another tool to consider is ICX from Mentor Graphics.
This uses the ELDO simulator (Mentors own SPICE simulator). It others
comparable features to SpectraQuest but you don't have to get an
addtional SPICE simulator.
For all the tools most IC vendors offer good support in both models and
deisgn kits.=20
Cheers,
Jonathan
