Good points about etch length and edge rates.

Somewhere else in the discussions the issue of programmable drive was also
brought up. We are using progarmmable drive strength and a fixed series source
terminator (selected by daughter card loading) in at least one instance.

Does anyone know a signal integrity simulator that is up to snuff on IBIS 3.2
especially with regard to the conventions on programmable devices and has
automated the handling of such parts?
