Futures Subcommittee l Proposed New Futures Subcommittee l

Futures Subcommittee l Proposed “New” Futures Subcommittee l l To create, discuss and draft IBIS/ICM updates Tasks for IBIS 4. 2 and Following l “Clean up” of language and resolve conflicts l l [External Model] integration issues l l Example: Acceptable digital states for input ports [External Circuit] usage issues l l Example: [S. Pin Mapping] (BIRD 87), [Driver Sched. ] (BIRD 88) User-definable measurement parameters and delay fixtures Specification “hooks” between ICM and IBIS ANSI ballot approval as 656 -B Tasks for ICM l l Add frequency-dependent RLGC matrix support Resolve known parser assumptions and keyword conflicts 01/30/04 *Other brands and names are the property of their respective owners 1

Cookbook & Training l Proposed Cookbook Subcommittee l l Joint action with Quality Subcommittee Creates, edits and distributes Cookbooks l l Suggest following model of HTML specification guides l l l Practical examples of new keywords Hints for data extraction and correlation See S. Peters’ 1997 IBIS 2. 1 Cookbook Describe all keywords Use “deprecated” for those no longer encouraged l e. g. , [TTpower] Separate ICM and IBIS publications 01/30/04 *Other brands and names are the property of their respective owners 2
