====================================================================== IBIS FUTURES/COOKBOOK SUBCOMMITTEE MEETING MINUTES Date: May 6, 2004 Attendees: Cadence Design Systems - Lance Wang Cisco - Syed Huq Green Streak Programs - Lynne Green Intel Corp. - Michael Mirmak, Arpad Muranyi Mentor Graphics - John Angulo Teraspeed Consulting - Bob Ross ====================================================================== Next Meeting: Thursday, May 20 1 PM - 3 PM US Pacific Time Telephone Bridge Passcode 916-356-4261 1 002-8565 Agenda: 1 - 1:15 AM Opens & Parser Bid Discussions 1:15 - 2 PM Cookbook Discussion - Review of IBIS Cookbook Outline - Review of ICM Cookbook Outline 2 - 3 PM Futures Discussion - User-definable Measurements Proposal (Mirmak) - Re-use of Port Names (Muranyi) - tentative - Re-submit of BIRD42.3 (all) ====================================================================== The committee meetings began with a review of IBIS parser bids received so far. This discussion is documented in a separate set of minutes. COOKBOOK MINUTES No Cookbook agenda items were discussed. The current outline will be reviewed in the next meeting. ARs: John Angulo - provide overview of differential model extraction details Michael Mirmak - create outline using current examples of above model types ====================================================================== FUTURES MINUTES Arpad continued his presentation on user-definable measurements. He noted that he is not proposing a specific syntax, but instead reviewing the concepts any system would need to cover. The key question to answer is: should a measurement system provided through the specification, provide only buffer-level characteristic information, or should it also cover system-level response? At present, most measurements are considered "local" to the buffer. Arpad suggested creating a standard "AMS probe" and "AMS load" code set to help automate measurements under IBIS 4.1. A variety of suggestions were made for implementation. Additionally, EDA tool representatives asked again for "canned" routines and measurements to cover standard overshoot, settling and other behaviors important to SI work. Consensus focused on the need for a "palette" approach to measurement, where tool expectations could be set but users would still have flexibility. Discussion will continue at the next meeting. ---------------------------------------------------------------------- For reference, the seven original BIRD proposals are listed below: 1) Define accepted digital states for input and output ports on IBIS 4.1 AMS models 2) Provide explicit links between ICM and IBIS 3) Expand [Circuit Call] to accept native IBIS [Model] and [External Model] references 4) Define series links between pins, pads and/or nodes under the multi-lingual extensions 5) Create user-definable buffer delay and input threshold measurements 6) Permit re-use of port names under [External Model] 7) Permit native IBIS data to be linked through external file names, similar to the multi-lingual extensions Attendees were assigned to complete formal proposals or definitions for the above, as follows: 1) Ian Dodd 2) Michael Mirmak 3) John Angulo 4) Ian Dodd & Bob Ross 5) Lance Wang, Ian Dodd and Arpad Muranyi 6) Arpad Muranyi 7) Lynne Green The formal statements should include a problem statement and a general outline of the solution.
