Hi Chris:

I have found the IBIS2XTK program to be efficient for conversion of
IBIS models based on version 2.1.

However, it appears that the program has more limitations for
converting IBIS models which are created in accordance with version 3.x.
For example, recently I had to convert an IBIS model, version 3.1, of
a CMOS Bus Switch. The XTK models which resulted after execution of
IBIS2XTK required significant manual editing to become functional.
