Since no one else has replied, I will take a stab at it. 1) The RLC lumped package parameters are REQUIRED by IBIS syntax. Many tools have minimum values for these parameters. If minimum values are an issue, it might be necessary to include a simple package model to insure the tool does not use the RLC pkg values. 2) The IBIS buffer data and the S-parameter data are maintained in separate files within IBIS. 3) The S-parameter model is presently connected at the "schematic" or "layout" level in most tools. This means the user has to connect the package ports to the package pins or pads. This is expected to be fixed in IBIS 5.x. 4) For customer use, an Application Note or web-based Design Kit is invaluable. This could, for example, show the easiest way for the customer to hook up the package and chip. Best of luck! Lynne "IBIS training when you need it, where you need it."

Is it possible to include s-parameter definition for a package into an IBIS model, or it is necessary to have the lumped RLC equivalent? So far we have only available the s-parameters model for the package, but we don't know how to include this info into the IBIS model... We will really appreciate your feedback regarding this point. Thanks in advance!!!
