Hi folks,
I am currently involved in defining company signal integrity standards for
verification testing of prototype pc boards.
Due to the varied digital component technologies (ie ttl, cmos,ecl) used
accross the our product lines, I am attempting to
define TECHNOLOGY INDEPENDENT guidlines for such things as:
-positive/negative overshoot/undershoot
-setup/hold margins
-transition region glitches
-Vcc AC variations on component pins

Any of you signal integrity guru's have any suggestions or ideas for

Thanks for any info!!!

p.s. I review my si-list email everyday. I enjoy following the communications
between si-list members, but
find choosing the favorable viewpoint to be most challanging!! Keep
it coming.
