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 we are still at 30 members. We are in discussions with another new member that would bring the total to 31. We are under budget for this time of the year, however we are expected to have a deficit by the end of the year. This deficit will hopefully be taken care of through ICM parser license purchases. REVIEW OF MINUTES AND ARS Michael Mirmak reviewed the minutes of the August 26, 2005 IBIS Open Forum teleconference. Michael pointed out that the Summit date was listed incorrectly as September 26 instead of September 19. The minutes were approved with the noted change. PRESS AND WEB PAGE UPDATES Michael Mirmak reported for Syed Huq that there was an update to the roster page to remove two companies from being listed with member status who are currently non-members. A change was also made to the FAQ page. MAILING LIST ADMINISTRATION Bob Ross reported that everything is normal. NEW MODELS AVAILABLE, LIBRARY UPDATE Michael Mirmak reported for Lance Wang that an update has been made to the library page. MISCELLANY/ANNOUNCEMENTS None. OPENS FOR NEW ISSUES Michael Mirmak mentioned that he would like to discuss the ICM parser. 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). Bob Ross reported that IEC TC47/SC47A are holding some working group meetings in Austin, Texas at the Freescale Semiconductor facility on October 17-19 for WG9 and October 20-21 for WG2. These meetings include IMIC and ICEM advances and will have international participation. The Electrical Perfomance of Electronic Packaging (EPEP) conference is being held in Austin Texas on October 24-26. Some material is of interest to IBIS. FDL'05 Forum on Specification and Design Languages is meeting in Lausanne, Switzerland on September 27-30. A IEEE 1076.1 (VHDL-AMS) working group meeting is also scheduled on September 27, 2005. EIA/ANSI APPROVAL ACTIVITIES Randy Wolff reported that ICM 1.1 balloting will close on September 26, 2005. So far there are 22 YES responses received, so the ballot has unofficially passed. Once the ballot passes, the standard can begin the ANSI approval process. SUMMITS - DesignCon East IBIS Summit DesignCon East will be held in Worcester, Massachusetts from September 19-21, 2005. September 19 will be the IBIS Summit. Bob Haller reported that he has the room, screen, laptop, and projector reserved. Everyone is pre-registered for lunch. Bob will setup the booth. The booth is in a premier location near the front entrance. Michael Mirmak said that he has a new banner for the booth. He will send it to the Bob's home. - Asian IBIS Summit December 6, 2005 is the official date of the Summit. It will be held at the Crown Plaza Hotel in Shenzhen, China near Hong Kong. The steering committee is headed by Jiang Xiang Zhong of Huawei. Financial sponsors include Sigrity, Zuken, Huawei, Cadence, Mentor, and SiSoft. Bob Ross plans to begin reviewing presentations soon. There are three presentations from Chinese telecom companies. For VISA reasons, Huawei can supply a letter of invitation to participants from outside of China. Contact Bob Ross or Lance Wang if you need such a letter. Sponsorship opportunities for DesignCon East and the Asian IBIS Summit are still available, with sponsors receiving free mentions in the minutes, agenda, and other announcements. IBIS QUALITY COMMITTEE Bob Haller reported that BUG90 was submitted. An adhoc presentation on this will be presented at the summit. The link to the quality committee checklist is at: http://www.eda.org/pub/ibis/quality_wip/ IBIS MODEL REVIEW COMMITTEE Michael Mirmak reported for Lynne Green that one new model was received. FUTURES AND COOKBOOK COMMITTEES Michael Mirmak reported that there were meetings of both committees once per week over the last three weeks. Futures meetings are being held every week to facilitate BIRD95 discussion. The meetings included brief reviews of the cookbook, discussions of a draft BIRD100 for linking of IBIS and ICM, and many presentations on BIRD95. Recent committee material is stored at: http://www.ibis-information.org/futures/ MACROMODELING LIBRARY COMMITTEE Arpad Muranyi reported that there was not much activity recently. The committee is preparing a presentation for the summit that will introduce the library. They are finding limitations in the Verilog-AMS language that are presenting difficulties. Arpad plans to make a VHDL-AMS version of the library. Committee material can be found at the following url: http://www.sisoft.com/ibis-macro/ COOKBOOK DISCUSSION Michael Mirmak reported that draft 7 of the cookbook has been posted to the website for over two weeks. Michael asked for any comments on the cookbook. There was a call for vote on approval of the draft cookbook as the final cookbook for IBIS 4.0. The vote passed with the following vote tally: Cisco - yes Intel - yes LSI - yes Mentor - yes Micron - yes Siemens - yes Sisoft - yes Teraspeed - yes Michael planned to prepare a final copy by removing draft text. He will print out a copy for use at the summit. The file will be put onto the IBIS EIA website. The final draft of the cookbook will be available at: http://www.eda.org/ibis/cookbook/cookbook-v4.pdf NEW ADMINISTRATIVE ISSUES Michael Mirmak reported that the ICM 1.1 parser is now offered in a private code (non GPL) version. He is working on removing any GPL related code and adding correct copyright notices. There are web page updates in progress to give out more information to potential customers. BIRD94.2: CLARIFICATIONS ON [DIFF PIN] PARAMETERS Arpad Muranyi reported that BIRD94.2 is ready for an approval vote. There was a call for vote on approval of the BIRD as an addition to the next version of the IBIS specification. The vote passed with the following vote tally: Cisco - yes Intel - yes LSI - yes Mentor - yes Micron - yes Siemens - yes Sisoft - yes Teraspeed - yes BIRD95.6: POWER INTEGRITY ANALYSIS USING IBIS Syed Huq reported that there have been several discussions on BIRD95.6 in the Futures committee meeting. The Futures website contains many relevant presentations. C_comp and package parasitic modeling are major issues being discussed relative to this BIRD. Cisco is planning to share its simulation database with Cadence for further correlation work. A vote is scheduled for BIRD95.6 at the next meeting. BIRD97.2: GATE MODULATION EFFECT Arpad Muranyi has been learning many things from the BIRD95 discussions that may apply to this BIRD. Arpad mentioned some issues in the gate modulation algorithm. The scaling relationship drafted in BIRD97.2 takes the DC supply voltage and uses it to scale the I-V curves, so this is done only in a DC sense. If high frequency noise is present on the gate, the output changes inconsistently with how DC noise affects the output. Arpad is looking for a better way to define these relationships. Arpad mentioned that in BIRD95.6, one splitting coefficient for C_comp is not consistent. Different coefficients for pullup and pulldown cases of the driver may be needed. Attenuation and phase shift for noise on the gate of the driver is dependent on how C_comp is defined, so C_comp relationships related to BIRD95.6 will have an effect on BIRD97.2. BIRD98: GATE MODULATION EFFECT (TABLE FORMAT) See BIRD97.2 for discussion related to BIRD98. IBISCHK4 BUG STATUS Michael Mirmak reported that there are seven BUGS still open, and they have all been classified. Four of these BUGs are easily remedied with changes to the parser compilation options. ICMCHK1 BUG STATUS Michael Mirmak reported that there has only been one BUG so far, and it has been closed. However, he thinks that fixing this BUG will actually open up a second BUG. NEW TECHNICAL ISSUES None. NEXT MEETING The next IBIS Summit will be held September 19, 2005. A teleconference has been arranged. The next IBIS Open Forum teleconference will be held October 7, 2005 from 8:00 AM to 10:00 AM US Pacific Time. A vote is scheduled for BIRD95.6. ============================================================================ 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.
