All, In the Friday Open Forum meeting Arpad raised a question that reflects the problem that legacy IBIS combines both package and die models in .ibs files. I believe the answer to this question is to split up "components" into a package EMD file and a die IBISx file. The enclosed presentation illustrates this using the example legacy IBIS file in my last presentation.
