Sunil,
As a user of ICX for 4 years, here is my opinion (worth about 2 cents) :
Once you are familiar with the setup of ICX it becomes an accurate SI tool
(a good example of setup is making sure the Time resolution is changed from
its default of 50ps to something less - I choose 16ps). It doesn't take too
long to become familiar with it - to me, it is a very intuitive tool. When
I analyze a board, I continually review my setup to make sure the results I
get are going to be accurate. Things like stackup, material properties,
corner cases, delay calculation method, rules, and appropriate ibis models,
are some of the things I check after each translation.
Once you have a good SI analyzer the key to accuracy will be the ibis
models. Mentor has a library of measured models that I would describe as
excellent - and they will make your custom ones for a reasonable price and
schedule. We have compared these models to lab measurements, and when we
are very careful with the measurement, we see good accuracy.
best regards,
jim

I think that is not reasonable.
I am using ICX for about 3 years and have got the same question.
But now, the equipment such as oscillosope, network analyzer is not
believable.
For example, the pcb manufacturers are sure that as the Impedance TDR, the
Impedance value is not same with TDR vendors.
As a result, which one is better between physical prototype and virtual
prototype.
I don't know more but I am preparing the comparison oscillosope's waveform
and probing result in ICX.
Good luck.

Subject: [SI-LIST] accuracy of ICX
Hello everybody,
I am evaluating Mentor's IS_Floorplanner for signal integrity analysis.
Due to time constraint, I can not practically test the accuracy of the
tool by making a prototype. Can anybody provide me details on
IS_Floorplanner's accuracy, particularly in the case of crosstalk
analysis?
Thanks,
Sunil
