All, Enclosed is a zip file containing a presentation and implementations of "legacy.ibs" in legacy IBIS format, using legacy IBIS files with parameter tree sections, splitting the IBIS file into an EMD file (parameter tree format) and a bare-die legacy file, and finally converting the bare-die legacy file into an IBISx file. Mike L, Can you post this please to the IBIS Reflector. Walter Walter Katz <mailto:wkatz@xxxxxxxxxx> wkatz@xxxxxxxxxx Phone 303.449-2308 Mobile 303.335-6156
