Walter,

Thank you!  So, someone using IBIS-AMI models with valid traditional data in a 
workflow should expect changes in the IBIS TX C_comp or V-t (or [Ramp]) data to 
have an impact on the results provided by the receiver in an IBIS-AMI-based 
flow, assuming nothing else changes?

MM,

The Legacy part of an IBIS model is used to generate the Impulse Response of 
the channel.

One method of generating the impulse response is to do a step response, and 
take the derivative of the waveform at the Rx input.

A simulator uses a combination of the Tx [Voltage Range], C_Comp, IV, VT and 
Ramp data, and the Rx C_Comp and IV data. Of course, [External Model] can also 
be used by a simulator.

The following required Tx IBIS fields are not used in the AMI flow:
Vmeas
The following required Rx IBIS fields are not used in the AMI flow:
Vinl
Vinh
