(Unofficial) IBIS Tree Diagram for IBIS Version 4.0 Michael Mirmak (Intel Corporation) (Based on Work by Ogawa-san of NEC & Bob Ross of Mentor Graphics) 3/26/03 Revised 3/24/04 IBIS Tree (IBIS VERSION 4.0) Entries new at versions 2.1, 3.2 and 4.0 are noted. (m) indicates that keyword or subparameter may occur multiple times. (ml) indicates that keyword may occur multiple times at any location. * indicates that enumerated selections for the keyword or subparameter are provided at the end of the document (other than possible reserved entries NA and NC). .ibs FILE --------- |-- File Data Section | ----------------- | |-- [IBIS Ver] | |-- [Comment Char] (ml) | |-- [File Name] | |-- [File Rev] | |-- [Date] | |--
