SI experts: I had a question about generating IBIS differential models. I am now working on generating the LVDS input IBIS buffer model with 100ohm on-chip-termination resistor. I was told that there is no specification for creating differential IBIS files. The I-V curve of [ground_clamp] and [power_clamp] can be generated using the voltage and current on the input pad, so the I-V curve of [ground_clamp] and [power_clamp] are identical. It does not make sense to me, if there is no standard to create differential IBIS file, how the different EDA company create the differential buffer model in their tools?
