Hi all:
I would like to know if we give u an IBIS model or .EBD file of a DIMM.
That model will probably be attached to the pin of the connector. We are
interested to know how do u probe software wise what is the quality of the
signal and time delay at each pin of every device on the DIMM attached to
the net being simulated.
The quality of the signal at the pin of the connector for a net with many
devices attached to it like an Adress line, would be a cummulative effect of
all reflections from all devices attached. Probing at the Pin of the
connector will show a signal quality that is not representative of the
quality at the pin of each device attached to the net. Therefore, we would
like to know from you how do u differenciate between the signal of the net
at the pin of the connector from the signal at the pin of every device
attached to the net.

Any feedback will be greatly appreciated.

Bouchra
