Please be aware that over a year ago, we proposed to IBIS ATM using
on-die S parameters to solve a number of problems, including proper
modeling of the on-die circuit elements. We've worked with several
companies who use on-die S parameters because they feel it's a better
way to model the analog behavior of the pin electronics. To date,
such models must be considered to be proprietary and non-compliant
with IBIS because there has been no action on the on-die S parameter
proposal.
I think it's a great idea. I just want to understand the thinking
regarding commonly used compensation networks that cause the receiver
(or transmitter) node to present itself as a high impedance, since I've
not seen anyone write about this.
