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 have 31 members as of today, now that Freescale has rejoined. The budget deficit has been reduced to $2000, and this should be cleared with two expected ICM parser purchases. REVIEW OF MINUTES AND ARS Michael Mirmak reviewed the minutes of the September 16, 2005 IBIS Open Forum teleconference and the September 19, 2005 IBIS Open Forum Summit. The minutes of both were approved without change. PRESS AND WEB PAGE UPDATES Syed Huq reported that he had added Freescale to the member list and added the Sigrity logo. He needs to make changes to the events page. There was some downtime on the EIA server, but this did not affect anything. MAILING LIST ADMINISTRATION Bob Ross reported that there are three email addresses treating IBIS mail as SPAM. He is trying to resolve this issue. NEW MODELS AVAILABLE, LIBRARY UPDATE No update. MISCELLANY/ANNOUNCEMENTS None. OPENS FOR NEW ISSUES Bob Ross mentioned that a BUG report received from TI turned out to not be a BUG. INTERNATIONAL/EXTERNAL PROGRESS BMAS 2005 Conference Summary Arpad Muranyi gave a summary of the Behavioral Modeling and Simulation conference that he attended. BMAS is part of the IEEE and is language independent. Discussions at the meeting were on behavioral modeling techniques. Most presentations were on VHDL design, modeling, and simulation. Arpad was invited to present next year in the meeting on what we are doing in IBIS. Arpad made a good contact with a university professor and will discuss modeling with him more. 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 mentioned 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. EIA/ANSI APPROVAL ACTIVITIES Randy Wolff reported that he has attempted contacting the GEIA twice for official results of the ICM 1.1 EIA balloting. He has not received any confirmation of the vote results yet; however, the unofficial count showed the ballot passing unanimously with 22 members voting. Randy plans to have an update at the next meeting including an official vote count and word of continuing activities with submittal of ICM 1.1 for ANSI approval. SUMMITS - DesignCon East IBIS Summit Bob Haller reported that the Summit went well, but it would be better to have a larger audience. No logistics issues arose. Michael Mirmak extended thanks to Cadence, Mentor, and SiSoft for their sponsorship. The booth has been returned and now includes the IBIS banner from Michael. Bob Ross mentioned to Bob Haller that he needs to submit the bill soon. - 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. One sponsor dropped out, and the financial sponsors now include Sigrity, Huawei, Cadence, Mentor, and SiSoft. Bob Ross reported that the program is full. There are five presentations from Asia and seven from the US. The list of presentations will go out next week. Sponsorship opportunities for 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 the committee met October 4 and the next meeting is November 1. They talked over how various companies do quality checks currently. They plan to review Michael Mirmak's draft parser specification next time. The link to the quality committee checklist is at: http://www.eda.org/pub/ibis/quality_wip/ IBIS MODEL REVIEW COMMITTEE Lynne Green reported that no new models have been received in the last three weeks. Most models coming in are using S2IBIS2 for model creation, and she is encouraging people to use S2IBIS3. Bob Ross mentioned that there is some concern with S2IBIS3 not working under all Linux versions. 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. There have been no new discussions on the cookbook since it was released. Futures discussions will be on power delivery topics for the foreseeable future. Recent committee material is stored at: http://www.ibis-information.org/futures/ MACROMODELING LIBRARY COMMITTEE Arpad Muranyi reported that they met last week. All buffer types except ECL are now implemented. The first version of the library should be completed next week. Arpad will need people to start using the library, write macromodel templates, and encourage tool vendors to be able to read these models. Bob Ross mentioned that the entire library is structured as analog components for use in non-AMS tool engines. Arpad will be soliciting feedback on the library. Committee material can be found at the following url: http://www.eda.org/pub/ibis/macromodel_wip/ NEW ADMINISTRATIVE ISSUES Bob Ross mentioned that there were emails recently concerning compilation of S2IBIS3 in Linux, and it won't work if you don't have the latest version of JAVA installed. Ambrish Varma will be notified of these problems. BIRD95.6: POWER INTEGRITY ANALYSIS USING IBIS Syed Huq reported that there were no additional updates to the BIRD. He summarized that this BIRD has been worked on since December 2004. The BIRD started out much larger and was broken down eventually to tackle a smaller portion of power delivery, namely SSN simulations. Syed thanked everyone involved in working on the BIRD. Arpad Muranyi asked about perhaps re-ordering the agenda in order to present his special topic first, as it is related to power delivery issues. Michael Mirmak asked whether it would have a direct relation to the BIRD95.6 vote. Arpad did not think it would. Several other members expressed that they would like the vote to continue. Arpad was asked to give a quick summary of his presentation. John Angulo mentioned that Arpad's presentation was related to test setups of BIRD95.6 evaluation, but not directly to the BIRD. John asked that Cisco mention how they handled the Micron model that had multiple power supply connections. Zhiping Yang said that if you were only interested in the power supply connected directly to the buffer driver transistors, the BIRD is ok. If you are interested in noise on the other power supplies, then it does not tell you this information. Zhiping said that it is important to hook up the other power supplies correctly in HSPICE so that they do not introduce noise into the driver supply, otherwise you can not correlate between HSPICE and IBIS. John said that the question is whether this BIRD would cover most buffers or only a few. Zhiping felt that additional I-t tables could be introduced in the future to cover future buffers. Arpad said that in light of macromodeling work, this could probably be modeled without IBIS specification changes using macromodels. Syed felt that this proposal should be part of the IBIS specification so that there could be multiple ways of modeling these effects. Ambrish Varma asked about whether the I-t table values could be measured in the lab. Zhiping said that it would be difficult if the I/Os and the core shared the same power supply. John Angulo mentioned that this BIRD does not completely solve power supply modeling issues, and it will have to be supplemented by other BIRDs. Lance Wang commented that he did not like the idea of breaking power delivery issues up into smaller pieces; that he would like to see one complete solution. Syed mentioned that this BIRD had started out modeling many effects and was purposely broken down into smaller pieces. There was a call for vote on approval of the BIRD text for inclusion in a future version of the IBIS specification. The vote passed with the following vote tally: Agere - abstain AMD - yes Cadence - no Cisco - yes Fluent - yes Green - yes Intel - abstain Marvell - yes Mentor - yes Micron - abstain NEC - yes Siemens - yes Sisoft - yes Sigrity - yes Synopsys - yes Teraspeed - yes TI - yes Xilinx - yes SPECIAL TOPIC: PHASE DELAY AND POWER DELIVERY Arpad Muranyi presented some material on an experiment related to gate modulation. Arpad used his "IBIS class" transistor model to look at gate modulation. Lynne Green asked about the bulk node of the transistors. Arpad responded that this node was always tied to the respective die power or die ground. Arpad investigated the response of the output node and the gate voltage node with a supply voltage changing by one volt over various ramp rates. His conclusions were that the output transistors do not follow rapid supply voltage variations instantaneously, so the gate modulation effect cannot be modeled by DC measurements alone. So, the AC effects need to be included in BIRD97/98 before these BIRDs can be completed. Arpad's presentation can be found at the following link: http://www.eda.org/ibis/futures/Quiet_line_experiment.pdf BIRD97.2: GATE MODULATION EFFECT No discussion - see the special topic above. BIRD98: GATE MODULATION EFFECT (TABLE FORMAT) See BIRD97.2 for discussion related to BIRD98. IBISCHK4 BUG STATUS No new BUGs to discuss. ICMCHK1 BUG STATUS No new BUGs to discuss. NEW TECHNICAL ISSUES None.
