Hi,


This is regarding ibis model parameters.


The parameters Vmeas, Cref, Rref, Vref are optional

–Ref: Page No 47, Table 5.3 – IBIS [Model] Sub parameters,  IBIS MODELING
COOKBOOK For IBIS Version 4.0


The datasheet of a particular device mentions timing measurements against
some specific loading which is different from its ibis model Cref and Rref
. In this case can one edit the Cref and Rref  in the ibis model to match
datasheet’s loading values so that timing values specified in datasheet can
be used in the timing model of Signal Integrity simulation tool ?
