if u want a little secret....
at 66/100MHz, don't worry about the si tools. if you use standard
parts like intel or amd chipsets, u should get a routing rules spec
that has min,max lengths. follow the rules and make sure you have
appropriate parallelism spacing. what you will need is length and
spacing reports from your pcb tools and some perl scripts to check
them. no need to simulate.
if you are designing on your own, use pspice or specctra or mentor
or whether u know and do some preroute simulations to generate the
rules and repeat the same steps above.
you have two more months to finish your stuff and graduate, don't
waste time on si tools. there are plenty of opportunity to learn
that when you start working. :-)

Subject: [SI-LIST] : [SI-LIST] SI tools

Hi,

I'm a senior computer engineering student interested in making a 66/100Mhz
board that would be utilizing GTL+ and LVTTL signals. What I really need
at this point is advice on SI testing and verification of layout. Since I'm
a
student, I have no real financial resources, but do have access to different
flavors of PSPICE, Cadence Specctra and most of the Cadence suite, along
with many Mentor Graphics tools. Any suggestions on the best place to
start? Also, I have the book 'High Speed Digital Design, A Handbook of
Black Magic' which seems to be helpful in real-world PCB issues.
