Mike...
We have been using SCICARDS software since 1976 to HELP design
complex multilayer boards. Our present designs are 14-16 layer, SMT
components (256 CQFP, 223 CPGA, etc) both sides, impedance controlled,
high critical run count (20%-40% of routes), etc. We have resisted
blind/buried vias and imbedded caps/res due to low production rate
and soft electrically definition.
Thru the years we have evaluated many packages including, but not
limited to Calay, Cadnetix, Racal, etc and have been told that we were
to transition over to Racal-Redac (6 yrs ago), Cadance (4 yrs ago) and
Mentor Graphics (now???). During all these years, good old SCICARDS has
just been sitting, out of the spotlight, knocking out designs while the
sales guys do over the managers, who have never worked on a design, and
convince them that their MAGIC PUSH BUTTON SYSTEM is better than sliced
bread. I love you SCICARDS, can I have your Bud..oops wrong commercial.
I may have gone into too much, but if you are evaluating a
software package, get the troops in the trenches involved and DON"T
believe anything the sales guy tell you....do it with YOUR benchmark.
My 10 cents and off the soapbox. Have a good day and good luck.
