Hello Peter,

Thought I would give you a couple of pointers to diode termination
information.

Schottky Diode Arrays by Eilhard Haseloff

Terminating Traces on High-Speed PCBs
by Steve Kaufer and Kelle Crisafulli

Published in the March, 1998 issued of Printed Circuit Design
or contact them at Hyperlynx.

I have had at least one design with high overshoot problems with
multiple driven PCI bus nets. The only solution, without major
component reselection, was diode termination to clamp the overshoot
problem to an acceptable level.

I would use them again and hope to see additional termination options
in future vendor simulation software for analysis purposes.
