All, Happy New year to everyone! I am enclosing the latest IBIS-ISS Package Status presentation. I plan on giving this presentation at the IBIS Summit on January 31. Slides 17, 18 and 19 are new, and document how the proposed syntax can be easily extended to have Ports refer to Input, Output or I/O model types. I also added a decision (1.4) for this on slide 23. In addition, I added decision 1.6: Corner? Typ/Slow/Fast Typ/LessXtalk/MoreXtalk Traditionally, IBIS has Typ, Min, Max values. This can mean either typical, smallest, largest, but can also take on the meaning of typical, slow/weak, fast/strong. For package models, a common meaning of corner would be Typ, Slow, Fast. This order is compatible with typical, slow/weak, fast/strong. Alternatively, one could have the meaning for delay, with the min delay being fastest and the max delay being slowest, thus Typ, Fast, Slow. To complicate things more, one could have corners for crosstalk. In any case, we will need to carefully define what we mean by corner, and might want to use other keywords then "Corner", such as "Delay_Corner" and "Xtalk_Corner". I hope we can resolve some of the "Decisions that are still unresolved" before the IBIS Summit, so we can focus on some decisions that I think need a wider audience then IBIS-ATM.
