CALL FOR PATENTS Michael Mirmak called for any patents or pending patents related to the IBIS Version 3.2, 4.0, 4.1, 4.2, or ICM 1.1 specifications. No patents were declared. MEMBERSHIP UPDATE AND TREASURER'S REPORT Michael Mirmak reported that we have 29 members officially recognized by GEIA. He mentioned that the cutoff is the DAC Summit for organizations to have their memberships renewed before they are dropped from the roster. REVIEW OF MINUTES AND ARS Michael Mirmak reviewed the minutes of the July 14, 2006 IBIS Open Forum teleconference. The minutes were approved without changes. PRESS AND WEB PAGE UPDATES Syed Huq reported that there were a few minor changes to the webpage to update dates relative to the summits. He also noted that the GEIA's response time has been very fast of late (approximately 2 hours). Syed Huq also requested an update on the GEIA's plans to upgrade their server. Michael Mirmak accepted an AR to confirm with the GEIA. Bob Ross noted two articles in the press published on IBIS activities or events. The first was printed in March, 2006 in EDN China regarding the December IBIS Summit in Shenzhen, People's Republic of China (article is in Chinese): http://www.ednchina.com/Article/html/2006-03/200635123740.htm An article on the IBIS Macromodeling Task Group was published in the EE Times in the July 24 print edition: http://www.eet.com/dac06/showArticle.jhtml?articleID=190900505 Ian Dodd noted that he believed the EE Times article inaccurately portrayed Mentor Graphics as opposing any API-related enhancements to IBIS. To clarify, Ian stated that Mentor Graphics is willing to consider both the AMS and API- based proposals. MAILING LIST ADMINISTRATION Bob Ross reported that the mailing list is working normally. NEW MODELS AVAILABLE, LIBRARY UPDATE Lance Wang reported no changes to the model library. Bob Ross suggested that a new company, Quimonda, a spin-off from Infineon, should be added to the model library. MISCELLANY/ANNOUNCEMENTS None. OPENS FOR NEW ISSUES Michael Mirmak noted that the GEIA has requested a change to the minutes format, to ease calculation of valid ballot votes. He addressed this in detail during the ANSI Approval Activities discussion. INTERNATIONAL/EXTERNAL PROGRESS Bob Ross mentioned two upcoming conferences as described in previous meeting minutes. The IEEE EMC conference is Aug 14-18 in Portland, Oregon. There may be peripheral interest in IBIS. More information on the conference can be found at the following url: http://www.emc2006.org/ The Electrical Performance of Electronic Packaging (EPEP) conference is October 23-25, 2006 in Scottsdale, Arizona. There are sometimes presentations related to IBIS at this conference. More information on the conference can be found at the following url: http://www.epep.org/ EIA/ANSI APPROVAL ACTIVITIES Michael Mirmak noted that the GEIA ballot of IBIS 4.2 had closed and that the results were being tallied. No official results were yet available but the liklihood of passage was very strong. He also noted that, per GEIA rules, votes were only counted from those IBIS members who had attended at least two of the previous three meetings, including Summits; membership payment is not the only requirement for GEIA balloting. In the future, the minutes format for the IBIS Open Forum summits and teleconferences will add eligibility data, to assist members and the GEIA in tracking eligibility. Bob Ross added that the comments he filed on the specification ballot would have to be addressed before the official document could be issued. The comments are entirely editorial in nature. Michael agreed and noted the comments would be discussed and incorporated into the final release. SUMMITS - DAC Review The DAC IBIS Summit was held July 25 at the Argent Hotel in San Francisco. Approximately 34 people from 23 organizations attended. Both Michael Mirmak and Bob Ross noted the significant turnout and the quality of the presentations delivered. The IBIS Board extends its gratitude to Cisco Systems, Green Streak Programs and Mentor Graphics for co-sponsoring the event. - China Summit The China summit date is finalized as Friday, October 27 in Shanghai at the Radisson Hotel Shanghai New World. An official announcement has been sent out. Huawei is the primary sponsor, with Ansoft, Cadence Design Systems, Intel, Mentor Graphics, Signal Integrity Software (SiSoft), Sigrity and Synopsys as co-sponsors. - Japan Summit The Japan IBIS Summit will take place Tuesday, October 31 in Tokyo at the JEITA offices. There should be a few presentations from overseas visitors with most presentations from local participants. The summit is planned from 9:00 AM to 3:00 PM followed by a separate JEITA meeting from 3:00 PM to 6:00 PM. JEITA is the primary sponsor, with Cybernet Systems and Synopsys co-sponsoring the event. An official announcement will be distributed shortly. - Other Events No update. Sponsorship opportunities for the China and the Japan IBIS summits are available, with sponsors receiving free mentions in the minutes, agenda, and other announcements. Contact the IBIS Board for further details. IBIS QUALITY TASK GROUP Mike LaBonte reported that, as reported at the DAC IBIS Summit, a draft of a new set of IQ designations has been proposed and is under consideration. The Task Group met August 1 and will meet again on August 22. A suggestion being pursued is to add a parenthetical notation to the IBIS Model Library to indicate organizations making use of the IQ system. The link to the quality task group checklist is at: http://www.eda-stds.org/ibis/quality_wip/ IBIS MODEL REVIEW TASK GROUP No update. FUTURES AND COOKBOOK TASK GROUPS Michael Mirmak reported that the most recent Futures Task Group had decided in favor of suspending meetings indefinitely. This was done after observing that the Macromodeling Task Group has been the subject of press attention and high attendance when discussing critical long-term IBIS issues. Rather than compete with this, the Futures Task Group would like to maintain efficiency by moving advanced development discussions to Macromodeling, with some pending Futures topics being handled by ad hoc groups. These pending topics include: an IBIS-ICM interface BIRD, Touchstone enhancements and standardization, support for [External Model] under [External Circuit] and gate modulation. Recent task group material is stored at: http://www.eda-stds.org/ibis/futures/ The Cookbook version 4 is stored at: http://www.eda-stds.org/ibis/cookbook/cookbook-v4.pdf MACROMODELING LIBRARY TASK GROUP Mike LaBonte reported that four of the DAC IBIS Summit presentations were discussed at the last meeting. Issues being handled by the task group include encryption, a general purpose interface to SI tools by models, and the use of a C-like API in addition to AMS for models. Cadence will be reporting additional progress on this proposal in future meetings. Ian Dodd expressed concern that an API interface that encouraged DLL distribution would run into problems supporting multiple machine and OS types. IBM had expressed disagreement with this point in the Task Group. SystemC might represent an alternative. Mike LaBonte added that this level of model complexity is only needed for the most sophisticated interface types. Ian Dodd clarified the differences between the "general purpose nonlinear simulator" such as SPICE, which can handle hundreds of cycles in relatively short periods, and the "linear simulator" which uses linear approximations of interface components and can handle tens of millions of cycles in relatively short periods. Ian concluded by stating that the phrase "signal simulator" is becoming the preferred term to use for SI-oriented linear tools, as opposed to "convolution simulator." On the topic of encryption, the team agreed that no further explicit work would be needed by the IBIS community, except to encourage tool vendors to incorporate the standard already in the recent Verilog and VHDL digital language editions. The timeline for the AMS languages to incorporate the encryption standard of their digital counterparts is unknown. Task group material can be found at: http://www.eda-stds.org/ibis/macromodel_wip/ IBIS 4.2 PARSER STATUS No new issues have been reported with the IBIS 4.2 parser. All development work has been closed, pending new BUG reports. NEW ISSUES Bob Ross noted that S2IBIS-related BUG reports had recently been filed with the IBIS Open Forum. Per Paul Franzon's summit presentation, S2IBIS3 development will likely cease once Ambrish Varma completes his degree work at NCSU. The IBIS Open Forum may contribute to efforts to raise funds to support future work. Syed Huq observed that having S2IBIS is advantageous to the IBIS community, as producers of commodity components may need it and may not have the resources to purchase or develop their own IBIS generation tools. The current tool is licensed by NCSU under terms which are not particularly restrictive. Making the code available on SourceForge may be an option to allow continued development by interested parties. Michael Mirmak raised some objections to open source methods on a personal level, but expressed no opposition to making the code available to developers, subject to NCSU approval. BIRD97.2: GATE MODULATION EFFECT No update. BIRD98: GATE MODULATION EFFECT (TABLE FORMAT) See BIRD97.2 for discussion related to BIRD98. IBISCHK4 BUG STATUS Bob Ross is continuing his discussion with Jon Powell about fixing BUG93. No other BUGs have been reported. ICMCHK1 BUG STATUS Michael Mirmak noted that no new BUGs have been reported. However, recent discussions in the Futures Task Group imply that a specification change may be needed to correct the usage of the term "port" so that S-parameter interfacing in ICM is clarified. NEW TECHNICAL ISSUES None. NEXT MEETING The next IBIS Open Forum teleconference will be held August 25, 2006 from 8:00 AM to 10:00 AM US Pacific Time. ============================================================================ NOTES IBIS CHAIR: Michael Mirmak (916) 356-4261, Fax: (916) 377-3788 michael.mirmak@intel.com Server Platform Technical Marketing Engineer, Intel Corporation FM5-79 1900 Prairie City Rd.
