Aldo,

The Quad tool XTK has been around a while and I would believe fairly
accurate. I have not personally used the tool but did work with a
designer 4 years ago who did. It is very $$$ and it has a very steep
learning curve, re-learning curve and the results need a fair amount of
filtering and interpreting. TLC came out later and is not cheap either.
Perhaps someone in the si-list community will give some current first
hand information.

As for Hyperlynx LineSim, I really like it. It is simple to use, and
the results are fairly
accurate. I have not done any extensive correlation with the actual
results, but what
I have seen on the bench are fairly representative to the graphical
results. The difficulty
was getting the IBIS files from each of the vendors, but I did get
them. LineSim was
very good for pre-layout and and simple experimentation (what-ifs). I
quickly wanted to
feed back the actual layout of many traces and run the results in
BoardSim. For the mimimal cost (compared to Quad) I would not hesitate
to get the entire HyperSuite.
If you can sacrifice some accuracy for ease of use, HyperLynx is the
appropriate solution.
