Hi Chris--
In your case I would strongly suggest looking at software tools targeted
at signal integrity and power integrity in PCB design. I think they
will let you get up to speed and getting results a lot faster than some
of the more general purpose tools out there. I agree with the other
posts about getting the tool vendor to come and run your design. Even
better would be if you can get your hands on the software and run it
yourself.
Your description below fit HyperLynx so perfectly I had to respond. If
you take a look at www.hyperlynx.com there are a bunch of papers and
on-demand webinars on performing SI and PI analysis, with subjects like
DDR2, multi-Gb serial, and DC Drop analysis. Feel free to contact me
directly with further questions as well.

Subject: [SI-LIST] Getting Started
I recently ran across a project where the power distribution on a
prototype board was botched, and some SI issues were suspected as well.
Which got me thinking, how can we prevent this sort of thing in the
future and get it right the first time? At the moment, our group doesn't
use any SI or power analysis tools, we've done very well on the basis of
experience and conservative design.
So for all of you out there: what sort of tools should I be looking at
if I am interested in validating board level power quality and SI? The
boards are large FPGA based, typically 8-16 layers, with DDR2 layout
being the main area interest for SI, along with a handful of
multi-gigabit serial signals. Assume for a moment that things like EMI
emission and susceptibility and analog circuit noise are (at least for
the time being) outside of my interest.
How do I get started?
Thanks,
Chris Maryan
