CALL FOR PATENTS Michael Mirmak called for any patents or pending patents related to the IBIS Version 3.2, 4.0, 4.1, or ICM 1.1 specifications. No patents were declared. MEMBERSHIP UPDATE AND TREASURER'S REPORT Michael Mirmak reported that since it is the beginning of the year, the participants list in the minutes has been cleaned up. Renewal notices have been sent out to participants. Bob Ross asked about Intel's parser payment. Michael was not sure if it was paid before the end of the year. REVIEW OF MINUTES AND ARS Michael Mirmak reviewed the minutes of the December 16, 2005 IBIS Open Forum teleconference. The minutes were approved without changes. PRESS AND WEB PAGE UPDATES Michael Mirmak reported that the GEIA server is online now, and updates to the eda.org server have been made. Bob Ross suggested we look at moving the site completely to the GEIA server. MAILING LIST ADMINISTRATION Bob Ross reported that everything is running normally. NEW MODELS AVAILABLE, LIBRARY UPDATE Michael Mirmak reported for Lance Wang that one link has been updated for ICS on the models page. MISCELLANY/ANNOUNCEMENTS None. OPENS FOR NEW ISSUES None. INTERNATIONAL/EXTERNAL PROGRESS There continue to be two pending standards under consideration by the International Electrotechnical Commission (IEC) under the technical committee TC47. Each of these standards have links back to IBIS. We are the appropriate committee to review and comment on these documents. The documents are available for technical review from Bob Ross. More information can be found at the following url: http://www.iec.ch The two standards are: IEC62404 I/O Interface Model for Integrated Circuits (IMIC) as 47A/704/CD (committee draft). This is a competing standard with IBIS and is an enhancement to spice languages. Models of Integrated Circuits for EMI Behavioral Simulation 47A/719/NP (new work proposal). This is a follow on to ICEM (ICEM is 62014-3). EIA/ANSI APPROVAL ACTIVITIES Randy Wolff reported that he had received no updates from GEIA on the status of the ICM 1.1 specification ANSI approval. Michael Mirmak reported that he had received an email from Chris Denham at GEIA stating that the close date for ANSI review is June 9, 2006. A brief discussion ensued on turning the Cookbook version 4 into a GEIA engineering bulletin. Michael confirmed that we can post a non-official version of the cookbook on our website and have an official version for purchase through the GEIA store. Further updates to the Cookbook may need to be finished before any voting occurs on the cookbook issue. SUMMITS - Asian IBIS Summit The Summit was held December 6, 2005 at the Crown Plaza Hotel in Shenzhen, China near Hong Kong. Michael Mirmak thanked all the sponsors and organizers of the event. He mentioned that he is still receiving questions and comments about the event from participants. Michael and Bob Ross are still working on a few financial issues related to the summit. - DesignCon The DesignCon Summit will be held Thursday February 9, 2006 in Santa Clara, California. Fred Balistreri is handling the registration. Bob Ross reported that the second announcement was sent out. Four presentations have been scheduled so far. Ian Dodd will be attending DesignCon, so he will take care of setup of the IBIS booth. Cisco will be a primary sponsor of the event. Bob recommended pre-registering for the DesignCon event soon. - DATE The summit will be Friday, March 10, 2006 in Munich, Germany. Michael Mirmak reported that Ralf Breuning sent out the second announcement recently. Sponsorship opportunities for DesignCon and DATE are still available, with sponsors receiving free mentions in the minutes, agenda, and other announcements. IBIS QUALITY COMMITTEE Bob Ross reported that the next meeting will be January 10. Mike Labonte is serving as a temporary chair during the transition of Bob Haller leaving as the chair. The link to the quality committee checklist is at: http://www.ibis-information.org/quality_wip/ IBIS MODEL REVIEW COMMITTEE No new models received. FUTURES AND COOKBOOK COMMITTEES Michael Mirmak reported that there were discussions in the Futures meeting on user defined measurements and on the lengths of model names and file names. The question arose about international participation in the meetings. It may make sense to hold special meetings at a different time to accommodate members in European and Asian time zones. Lynne Green had mentioned in the meeting several comments related to the Cookbook. There were specific comments related to the load used in the [Ramp] keyword. Bob Ross suggested that we make changes to the Cookbook before looking at turning the Cookbook into an engineering bulletin. Michael mentioned that he would like Lynne to create a document that will list the changes made to the Cookbook. Stephen Peters mentioned that the Touchstone 1.2 specification was never officially approved by the IBIS committee. Version 1.1 was officially approved. He requested looking into officially approving the 1.2 specification. Michael will find a contact at Agilent to discuss this with, and he will get this person into contact with Stephen Peters and Sam Chitwood. Sam would like to see the IBIS committee take on the standardization of the Touchstone format so that it is not controlled by any specific vendor. Recent committee material is stored at: http://www.ibis-information.org/futures/ MACROMODELING LIBRARY COMMITTEE Arpad Muranyi reported that there was a meeting this week. Presentation topics were discussed for the upcoming summit. Arpad is still working on the VHDL flavor of the library. Committee material can be found at the following url: http://www.ibis-information.org/macromodel_wip/ NEW ADMINISTRATIVE ISSUES None. BIRD97.2: GATE MODULATION EFFECT Arpad Muranyi reported that he received an email from Antonio Girardi in mid December. Antonio was planning to run more experiments. Antonio and Arpad are trying to determine how complex the BIRD needs to be. Michael Mirmak mentioned holding a special Futures meeting to discuss this BIRD further. BIRD98: GATE MODULATION EFFECT (TABLE FORMAT) See BIRD97.2 for discussion related to BIRD98. BIRD100.1: ALLOW PURE ANALOG *-AMS MODELS Arpad Muranyi reported that this version of the BIRD was posted in December. He has not received any comments on the updated BIRD. John Angulo asked about adding more examples to the BIRD. Arpad said that he updated the figures, but he did not add any examples yet. Arpad plans to make final changes next week so that the BIRD can be put up for vote at the next IBIS Open Forum meeting. BIRD101: SECTION 6B, FIGURE 12 EXAMPLE NOTE Bob Ross said that the purpose of the BIRD is to add one note above Figure 12 documenting that some of the material in Figure 12 is not part of the current specification. There are some pad to pin connections in the figure in anticipation of ICM linkage, however this linkage is not part of the specification currently. There was a call for vote on approval of the BIRD text for inclusion in the next version of the IBIS specification. The vote passed with the following vote tally: Intel - yes Mentor - yes Micron - yes Sigrity - yes Teraspeed - yes IBISCHK4 BUG STATUS Randy Wolff mentioned that he is working on a BUG report related to non-monotonic warnings in [Submodel] I-V curves. Specifically, separation of On-die Termination (ODT) characteristics from normal [POWER Clamp] and [GND Clamp] characteristics leads to non-monotonic regions in the ODT I-V curves. The recombination of the curves results in a monotonic curve, however the parser does not combine [Submodel] curves with the [Model] curves to check for overall monotonicity. Michael Mirmak mentioned that there are 8 BUGS filed currently that will need to be dealt with moving forward. ICMCHK1 BUG STATUS Michael Mirmak reported that a BUG has been filed that calls for making a repair to BUG1. Running the parser in very verbose mode, text blocks in the disclaimer over 1024 characters caused problems. This parser version also reports incorrect use of a text string field after [End ICM Section], as changed in ICM 1.1. If the original BUG1 demonstration file is edited to comply with ICM 1.1 rules, the hang issue returns: the parser provides many lines of output but never returns to a command prompt. Michael suggested that BUG2 be filed as moderate, medium, and open. Michael discussed how to make changes to the ICMCHK1 parser, as we can not rely on Kelly Green for making changes. Bob Ross suggested that we plan to make changes within the committee's resources, and ask Kelly about consulting on our changes. NEW TECHNICAL ISSUES None. NEXT MEETING The next IBIS Open Forum teleconference will be held January 27, 2006 from 8:00 AM to 10:00 AM US Pacific Time. A vote is scheduled for BIRD100. The next IBIS Summit will be held February 9, 2006 at DesignCon. No telephone bridge is available. ============================================================================ NOTES IBIS CHAIR: Michael Mirmak (916) 356-4261, Fax: (916) 377-1046 michael.mirmak@intel.com Senior Analog Engineer, Intel Corporation FM6-45 1900 Prairie City Rd.
