NOTE: "AR" = Action Required. -------------------------------- MINUTES ----------------------------------- INTRODUCTIONS AND MEETING QUORUM No new introductions. CALL FOR PATENTS Michael Mirmak called for any patents or pending patents related to the IBIS Version 4.0 standard. No companies declared a patent. MEMBERSHIP UPDATE AND TREASURER'S REPORT Michael Mirmak reported that the current membership still stands at 25 paid members. The "Voting members and 2003 participants list" which appears at the top of the minutes has been updated to reflect the 2003 membership. REVIEW OF MINUTES AND AR'S Michael Mirmak mentioned that the June 23, 2003 summit minutes and the June 27, 2003 meeting minutes needed changes to their participants lists to reflect the current year's voting members. The changes were approved by acclamation. Bob Ross added that the appropriate changes have already been made to the documents available on the web. MISCELLANY/ANNOUNCEMENTS No new announcements. PRESS AND WEB PAGE UPDATES Syed Huq reported that he has completed an initial review of the IBIS roster to reflect the current membership list. The response level has not been high. Bob Ross suggested that individual reminders be sent to unresponsive companies, based on known good addresses. In addition, Syed accepted an AR to replace the eigroup.org Futures Committee link with a direct link to the IBIS 4.1 specification. Syed also noted that an update to the Events page is in progress. NEW MODELS AVAILABLE, LIBRARY UPDATE Bob Ross reported that Roy Leventhal provided an updated model library to EIA on June 29 for the eigroup.org website. OPENS FOR NEW ISSUES No new issues. INTERNATIONAL/EXTERNAL PROGRESS - IEC 62014-3 (ICEM) Integrated Circuit Electromagnetic Model Proposal (formerly, IEC 93/67/NP IBIS and EMC Simulation) No report. - JEDEC Activity Report. Nothing to report. DATE/PCB EAST SUMMIT DISCUSSION Michael Mirmak reviewed the current plans for DATE/PCB EAST. An IBIS Summit is tentatively scheduled for Tuesday, October 21, but specific locations and times have not yet been determined. Bob Ross suggested that a call for papers be issued in mid-August. He noted that the attendance at this event has usually been good. DESIGNCON SUMMIT DISCUSSION Bob Ross observed that arrangements for DesignCon 2004 should be almost identical to those in previous years. Michael Mirmak and Stephen Peters noted that the DesignCon planners had already contacted them regarding co-sponsorship and other issues. Guy deBurgh mentioned that he has reserved time away from work for DesignCon and is willing to transport and set up the IBIS booth at the event. Michael thanked him for his efforts. Syed and Michael have accepted an AR to obtain the latest contact information for DesignCon to post on the IBIS web site. IBIS VERSION 4.0 PARSER FUNDING AND STATUS Michael Mirmak reported that the Open Forum has received a commitment from an additional company to purchase an IBISCHK4 parser license. This brings the total number of contributing organizations to nine, the original target. Invoicing will be completed through the GEIA. Stephen Peters stated that the GEIA had received payment from all other parser purchasers. Bob Ross noted that payment for the parser should be issued to the developer by the end of the year or earlier, if possible. Bob Ross noted that a beta version of IBISCHK4 had been compiled and is available for download at: http://www.vhdl.org/pub/ibis/ibischk4_beta IBIS VERSION 4.1 DISCUSSION Bob Ross reminded the Open Forum that a text version of IBIS version 4.1 is available on the web. Both the text and a PDF version are available at: http://www.vhdl.org/pub/ibis/wip/ Few comments have been received on 4.1, though parser author Atul Agarwal has addressed several key issues. Lynne Green and Bob Ross have been collecting feedback for future discussion. Stephen Peters suggested that formal readings of 4.1 begin during Open Forum meetings, to review each BIRD change individually. After three readings, the specification can be presented to the Open Forum for an approval vote. The Open Forum consensus was to address detailed technical issues in a separate committee with recommendations presented to the Open Forum for individual review and approval. Michael accepted an AR to establish a technical committee for 4.1 review. In addition, Stephen proposed specifically discussing the relationship between BIRD75, the [Ramp] keyword, and the C_comp subparameter in the next Open Forum meeting. IBIS QUALITY COMMITTEE Robert Haller reported that the Quality Committee met on July 15, with eight attendees. The Committee continues to meet every two weeks and holds good discussions. The next meeting is scheduled for July 29. IBIS MODEL REVIEW COMMITTEE Lynne Green reported that models have been sent to the Committee from Analog Devices in Ireland. These have been distributed to the Committee members. Lynne noted that EDA tool vendors are welcome to join the Committee. NEW ADMINISTRATIVE ISSUES No new issues. S2IBIS3 Bob Ross noted that a "first step" revision of S2IBIS3 is available from students at North Carolina State University (NCSU), specifically Ambrish Varna. This version is written in Java and does not support conversion of all keywords (for example, support for [Series Current] and MOSFET-related I-V tables is still in the planning stage). Syed Huq mentioned that he had installed Java and was actively validating the S2IBIS3 software. Syed also inquired about the Open Forum's policy toward development of software which generates IBIS models. Bob Ross stated that the Open Forum does not provide funds for development which competes with products produced by Open Forum members. Free, open source software may be linked through the IBIS web site. Michael Mirmak accepted an AR to obtain a link to the S2IBIS3 software for posting to the IBIS web site. BIRD82 - Clarification of Clamp Table Use Lynne Green and Robert Haller introduced BIRD82, which changes language in the specification to clarify how clamp effects are to be combined with pullup and pulldown data without double-counting. At present, there is no way to address double-counting issues with parser checks alone. Bob Ross raised several concerns regarding the syntax and format of the BIRD plus the suggestion that the specification should avoid making specific algorithmic recommendations. Lynne Green and Robert Haller will revise and resubmit the BIRD. BIRD74.4 - EMI Parameters Guy de Burgh reported that he had received additional comments on the syntax of BIRD 74.4 from Bob Ross and others. Guy will reissue the BIRD as 74.5 when all suggestions and editorial changes have been received and included. IBISCHK4 & BUG TRACKING STATUS Thanks to efforts by Guy deBurgh, Lynne Green and Bob Ross, a beta version of the IBISCHK4 parser, compiled for several operating systems, can be found at: http://www.vhdl.org/pub/ibis/ibischk4_beta Test cases will be provided to the Quality committee for their review. Bob Ross reviewed the procedure for approval of the IBISCHK4 parser. The beta code will be provided to all licensees for their review. All BUG reports, including the analysis of the developer, will be closed through review in the Open Forum. John Angulo noted that checking of BUGs 68 and 78 have yet to be completed. In addition, there were minor differences noted between the developer's reference output and the actual output of the software. IBIS ICM SPECIFICATION REVIEW Michael Mirmak reported that a single message was received as feedback on the IBIS Interconnect Specification (ICM), in response to the recent electronic call for review. The issue raised was substantially similar to comments made at the recent IBIS Summit. At this point, formal readings will be scheduled in the Open Forum to move the ICM toward an approval vote. NEXT MEETINGS: A brief discussion was held on whether to hold a meeting on August 29, before a major US holiday. Lynne Green suggested that, with the high number of documents now being analyzed, the meeting should be moved to August 22. This issue will be closed at the August 8 meeting. The next teleconference meeting is scheduled for August 8, 2003 from 8:00 AM to 10:00 AM Pacific Daylight Time. ============================================================================ NOTES IBIS CHAIR: Michael Mirmak (916) 356-4261, Fax: (916) 377-1046 michael.mirmak@intel.com Senior Analog Engineer, Intel Corporation M/S FM6-45 1900 Prairie City Rd.
