We own all 3 of the tools (Hyperlynx, XTK and ICX) here, and ICX definitely
is the best, and the one that's been implemented as the standard tool for
board level SI simulation.
With Hyperlynx you get what you paid for, it's good for simple analysis, not
nearly as accurate as ICX or XTK, the waveform viewer is primitive, and I
don't like the set up for entering your own nets. I think it should not be
compared to the other 2 tools.
XTK has the accuracy, but is much more complex and not nearly as user
friendly as ICX, learning curve is much longer, and the IBIS models need to
be converted into Quad format, which can add time and problems.
ICX takes in native IBIS models, supports the latest IBIS specs, is fast,
converts from routing tools easily, and the accuracy is very good.

Subject: RE: [SI-LIST] : XTK vs ICX
I disagree with the statement below that ICX is hard to use
and slow to
simulate. I believe it is very intuitive, and simulation
time for xtalk
analysis, etc., is very reasonable. I've used them both and
believe ICX
comes out on top. (But as Dennis Miller so aptly put it :
"It's just my
opinion, I could be wrong".)

Hi Tony,
It may be important what type of methodology you use in your
design.
Hyperlynx is easier to use than the others, but poor
functions such that
small waveform viewer window gives limited information, not
IBIS v.3.x
supported, etc.
ICX is great, if you design your PCB layout yourself, with
rule-driven
assistance router. Supporting IBIS v.3.x is good, but
multi-staged (or
some advanced function of ) QUAD model is not supported as
far as I
know.
You will need many time initially to use ICX as whole degign
checker,
because you must enter many parameters of rules database,
besides you
must wait for a long time during the calculation.
XTK is my favorite, but some more complex than the others.
You may need
to take a time to learn XTK, but with a help of good
documents, you will
soon make it use easier. Model support is great, IBIS 3.x is
of course.
It is not so sofisticated like other new tools, but text
(ASCII) based
databases are easy to manage than the other GUI oriented
tools in the
case of such as you stack with uncertain trouble.
My impressions are ...
