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 ...

                Hyperlynx ICX XTK
-------------- ------------------- ----------------- ----------------
Model Support **2** **3** **4**
(Native: IBIS 2.x IBIS 3.x Quad native )
(Board disc.: EBD TOPSPEC )
                                                        (non-coupled
                                                        line only)
(Converted: old-Quad IBIS 3.x )

Ease of Use **5** **3** **3**
                (Very easy! But (Sofisticated. (Need to learn.
                simple can do only But bit complex.) But is easy.)
                simple.)

Rule Checking **1** **5** **3**
                (You must do it (Great checking (Check by the
                manually.) functions.) report output.
                                                        Difficult.)

What-if **3** **3** **4**
"What is what-if is what you want to what-if function."(?)

Multi-board **1** **3** **4**
                (Can it ?) (Need x-tra cost.) (Need to learn.)

Tool support **4** **4** **3**
"If your CAD was interfaced, it is enough. Isn't it ?"
