Mike, You're correct; the existing IBIS spec for package modeling falls short in the multi-gigabit realm. While there are proposals being discussed to address this; they aren't part of the current spec. In current practice, people are either instantiating package models (usually as S-parameters) in their simulation schematics explicitly, or using tool-specific extensions to IBIS to include a more robust package model.
