CALL FOR PATENTS Stephen Peters 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 Stephen Peters reported that 33 IBIS dues invoices have been mailed, with three more pending. Stephen noted that the IBIS budget for 2003 assumes 25 member companies, and he urged companies who are intending to join not to delay their dues payment. This is so we know early in the year how many members we will have and can adjust the spending accordingly. Stephen also reported that the EIA has sent a check in the amount of $7,365 to Atul Argawal in partial payment for future development work on the IBIS 4.0 golden parser. The amount represented the balance of our EIA account for 2002 plus $4,000 from the EIA itself. REVIEW OF MINUTES AND AR'S Arpad Muranyi posted a message on behalf of Luca Giocotto regarding a correction to the December 13, 2002 minutes. In a reflector email titled "Re: [IBIS] IBIS open forum minutes (12/13/02)" dated January 8, 2003 Luca corrected some of Arpad's technical comments made during a discussion of BIRD79. The December 13, 2002 minutes will be amended to reflect Luca's comments. The rest of the December 13, 2002 minutes were approved without change. ARs will be discussed during the meeting. MISCELLANY/ANNOUNCEMENTS None reported. PRESS AND WEB PAGE UPDATES Stephen Peters reported that Syed Huq has updated the IBIS roster page with new entries for NEC Electronic Corporation. Syed mentioned that he is also updating the roster to remove Innoveda as a separate company, and Innoveda's representatives will be moved to the Mentor Graphics roster entry. Finally, Lynne Green noted that Chris Denham's e-mail address should be updated. NEW MODELS AVAILABLE, LIBRARY UPDATE Stephen Peters reported that Roy Leventhal updated the IBIS Models page on December 20, 2002. OPENS FOR NEW ISSUES None. INTERNATIONAL/EXTERNAL PROGRESS - IEC 62014-3 (ICEM) Integrated Circuit Electromagnetic Model Proposal (formerly, IEC 93/67/NP IBIS and EMC Simulation) - No report. ELECTION OF IBIS SECRETARY As reported previously, Guy de Burgh will be stepping down from his position of IBIS Secretary effective January 31, 2003 (after the DesignCon IBIS Summit Meeting in which he is coordinating the IBIS Booth). Stephen Peters nominated Randy Wolff of Micron to fill out the remainder of Guy's term starting on February 1, 2003. Bob Ross seconded the nomination and Randy was elected unanimously by roll call vote. Stephen will add Randy's contact information to the NOTES section of the minutes, and Bob Ross will update the web page contact information. DESIGNCON 2003 IBIS SUMMIT MEETING PLANNING Stephen Peters reported that planning continues for the DesignCon2003 IBIS Summit sponsored by DesignCon2003 and National Semiconductor. The summit is scheduled for Monday, January 27, 2003 in Santa Clara, California at the Westin Hotel adjacent to the Santa Clara Convention Center. National Semiconductor is supplying the lunch and Stephen reminded those planning to attend to visit the IBIS web page under the upcoming events link and sign up with Milt Schwartz. Stephen reported that Milt has received about 20 sign-ups. It was noted that Lynne Green has sent out a third summit announcement and Guy de Burgh has sent a request for IBIS placards for the IBIS booth to several new member companies. Placards are due to Guy by January 24, 2003. Stephen and Lynne are working together to modify the current IBIS handout to list the IBIS links and extra summit presentations will be available. Per IBIS by-laws Stephen will post the meeting agenda by Monday, January 20, 2003. Lynne will be contacting speakers starting next week. Milt would like presentations delivered by Tuesday, January 21, 2003 since he needs a few days to get copies from the copy center. It is best if presentations are done on a PC and sent as attachments. Stephen reported that no company has stepped forward to fund the full $700 dollars it would take to enable a webcast presentation with voice, therefore the webcast will not take place. Finally, Stephen noted that the following individuals have signed up to present at the summit (presentation titles are tentative) - Stephen Peters, Intel, IBIS Report - Dima Smolysansky, TDA Systems, TBD - Barry Katz, Signal Integrity Software, Quality Committee Report - Atsuji Ito, Matsushita (Panasonic), JEITA/IBIS Activity Report - Bob Ross, Mentor, TBD - Arpad Muranyi, Intel, Certain Effects in Differential Modeling - Tim Coyle, National Semiconductor, IBIS Modeling Experiences In addition, Michael Mirmak indicated that he will confer with Kelly Green and present on the ICM parser status. Again, other presentations are encouraged. DATE 2003 IBIS SUMMIT PLANNING Bob Ross reported that he has begun preliminary planning for the European IBIS Summit. This summit is held in conjunction with the DATE 2003 conference in Munich Germany, and a tentative date of Friday, March 8, 2003 has been selected. Because of travel restrictions, no one from the US has obtained commitment to travel to Europe. Werner Rissiek and the Zuken team (who were co-sponsors along with Siemens AG and Mentor) have volunteered to chair the meeting and take care of much logistics. Bob is still working with them on the details. It may be a morning/early afternoon meeting. An announcement should go out next week. Initially, Bob indicates that he estimates about 4-5 presentations. In response to a question from Bob, Stephen Peters will check the EIA bylaws and determine if this can be considered an official summit meeting. IBIS VERSION 4.0 PARSER FUNDING ISSUES Lynne Green reported that six companies have committed to help fund development of the IBIS 4.0 parser, and another three companies are probable. The goal is to have 10 companies committed at a minimum of $2,084 a piece before starting the project. However, given that we have already committed funds of $7,365 (see the Treasurer's report above) the nine potential companies would be enough to fund the remainder of the project. Stephen proposed sending the eight committed companies an invoice for $2,084 (Syed Huq reported that Cisco Systems has already sent payment to EIA). There was unanimous consent to this proposal. Lynne and Stephen Peters will continue to work on finding three (or more) additional companies to commit. Furthermore, Stephen will contact Atul Argawal and give him permission to begin development of the IBIS 4.0 parser, while informing him that we are still in the process of invoicing the funds. Finally, Lynne asked if Atul Argawal will also be doing the parser extension to cover IBIS version 4.1. Bob replied that the IBIS 4.1 parser extensions will go out for competitive bid. IBIS QUALITY COMMITTEE Lynne Green reported that IBIS quality committee met on January 7, 2003, and will meet again on January 21, 2003. The committee is still working on documents cleanup and preparing for the IBIS Summit meeting. IBIS MODEL REVIEW COMMITTEE Lynne Green reported no new models to review. NEW ADMINISTRATIVE ISSUES None. IBIS FUTURES AND CONNECTOR WORKING GROUP REPORT Lynne Green reported that the futures committee met on January 9, 2003 to review the comments received on the Draft 1.0 ICM Specification. Michael Mirmak and Kelly Green presented a high level summary of their comments. Comments were classified as editorial, clarification, and technical. Michael and Kelly Green will address the editorial and clarification issues, and present recommended changes to the draft at the DesignCon Summit. Technical issues will be identified, but no technical changes are planned. BIRD75.8 - Multi-Lingual IBIS Model Support BIRD77.2 - Differential Subparameter Additions Bob Ross reported that a revised BIRD75.8 was made available on the web site. Bob gave a quick summary of the major changes from the previous version. Bob Also mentioned that BIRD77.2 adds changes to support pseudo-differential models, but the additional 'model_types' introduced by BIRD77.2 have no meaning without also passing BIRD75.8. Bob also noted that changes can still be introduced to the multi-lingual modeling proposal using the normal BIRD process, but passing these two birds now will stabilize the multi-lingual syntax. Arpad Murani noted that reflector comments raised a concern regarding the intent of the [External Model] override within a [Model] keyword. It is not explicitly clear that a fully functional native IBIS model is still allowed under a [Model] that uses an [External Model] keyword. After discussion it was agreed that the clarification was needed, but it would be handled by a separate BIRD or the standard editorial process for IBIS 4.1. Likewise, Lynne Green noted that Figure 4 does not correlate with a specific example in the text, and she asked that this be recorded in the minutes for future consideration as an editorial revision. With no further discussion Stephen Peters called for a vote on both BIRD77.2 and BIRD75.8 together. Both BIRDs were approved unanimously. Bob will upload the final BIRDs onto the web site, changing their status to 'approved'. BIRD78.1 - Comment Line Length Limit After a quick summary of BIRD78.1 by Lynne Green, Stephen Peters called for a vote. BIRD78.1 was approved unanimously. BIRD80.1 - Add External Reference Column to Pin Mapping Keyword Michael Mirmak posted BIRD80.1, which updates the previous BIRD with various editorial comments and clarifications. After a short discussion, it was decided to schedule this BIRD for a vote at the teleconference meeting following the January Summit. BIRD81 - Clarify Usage Rule for [Pin] I/O Model Assignment Bob Ross introduced BIRD81, which was submitted by Lance Wang of Cadence. BIRD81 adds language to the [Pin] keyword description to clarify that series and series_switch model types cannot be used in the model field of a [Pin] keyword. Bob noted one minor editorial point, in that the added text needed to be prefixed with the comment character. Bob will upload the bird as BIRD81.1 with this change. A vote on BIRD81.1 is scheduled for the teleconference meeting following the January Summit. BIRD74.2 - EMI Parameters BIRD79 - Non-linear buffer impedance (extension to C_comp) Discussion on these BIRDs was deferred. IBISCHK3 & BUG TRACKING STATUS Stephen Peters noted that Michael Mirmak provided a Perl utility to produce an index to the BUG reports: http://www.eda.org/pub/ibis/bugs/ibischk/index.html Michael also upgraded the Perl script for the BIRD reports to correct a second line truncation artifact. - BUG71 - Monotonic Checking for Combined I-V Tables Bob Ross is waiting for Bob Haller to update the BUG report to clarify which I-V table combination are legal and illegal. Further discussion has been deferred. - BUG74 - Missing Timing Test Load Warning Messages Greg Edlund has updated this bug with clarification of assumed default values for Cref, Vref, etc. Further action is postponed until the rest of the Open Forum has had a chance to review the contents of the bug report. - BUG78 - Clamp Current Double Counting Test While this bug has a test case, it is still incomplete as to the bug specifics and how to detect the reported error. We will defer classification until we receive an update from Roy Leventhal. Bob Ross stated that the quality committee should identify a test to detect the case of clamp current double counting else there is little we can do to fix this bug. NEXT MEETING: The next meeting will be the IBIS summit meeting at DesignCon2003 on January 27, 2003. No phone bridge or webcast is planned. The next teleconference is tentatively scheduled for February 14, 2003. ============================================================================ NOTES IBIS CHAIR: Stephen Peters (503) 264-4108, Fax: (503) 264-1831 stephen.peters@intel.com Senior Hardware Engineer, Intel Corporation M/S JF4-215 2111 NE 25th Ave. Hillsboro, OR 97124-5961 VICE CHAIR: Lynne Green (425) 788-0412, Fax: (425) 788-4289 lgreen@cadence.com Senior Modeling Engineer, Cadence Design Systems 20 120th Ave NE, Suite 103, Bellevue, WA 98005-3016 SECRETARY: Guy de Burgh (805) 988-8250, Fax: (805) 988-8259 guy_deburgh@mentor.com Senior Manager, Mentor Graphics 1369 Del Norte Rd.
