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:
