I agree.

That is correct.

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
