He is the VP of Marketing for Lynguent working with AMS simulation model development tools. He has been in the EDA and test world for many years and worked with many companies in the Portland area. He is interested in the capabilities of IBIS. Otis Gorley of Texas Instruments in Sherman, Texas introduced himself. He works with linear logic parts and does design automation for creation of IBIS models. He is familiar with creation of IBIS 3.2 models and is interested in the evolution of IBIS. Antonio Girardi of STMicroelectronics introduced himself. He has been developing IBIS models of memory products for about six years. He is currently involved with the the Futures committee. 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 no changes since the last update. Texas Instruments is officially renewed as a member. We have closed off renewals for the year, but new memberships are being solicited. There are 30 members total. REVIEW OF MINUTES AND ARS Michael Mirmak reviewed the minutes of the July 15, 2005 IBIS Open Forum teleconference. The minutes were approved without changes. PRESS AND WEB PAGE UPDATES Syed Huq reported that the Green Streak logo was added to the poster page. Updates to the FAQ page is in progress. The events page is updated with new contact information for DesignCon East. MAILING LIST ADMINISTRATION Bob Ross reported that everything is working normally. NEW MODELS AVAILABLE, LIBRARY UPDATE Lance Wang is planning to review the library at the end of this month. MISCELLANY/ANNOUNCEMENTS Bob Ross requested an addition to the agenda - an IBIS macro model committee report. 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). Michael Mirmak reported regarding the Interconnect Modeling for Integrated Circuits (IMIC) specification. This standard developed by the EIA-Japan mentions IBIS. Michael said that the public comment period has closed, so no comments from the IBIS committee can be submitted until the standard is put through further development and approval processes. EIA/ANSI APPROVAL ACTIVITIES Randy Wolff reported that the IBIS 3.2 re-approval process for ANSI standardization completed the public comment period on July 25, 2005. This is considered the official date for ANSI approval. This completes the EIA/ANSI standard approval process, so the IBIS 3.2 specification is good for another five years. Also, Randy said that the ICM 1.1 EIA approval process is progressing, and the ICM 1.1 specification should begin the official public comment period soon. Bob Ross mentioned that international standards approval is due next year on the same five year cycle, so we will have to find the correct IEC representative to work with on this 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. Syed Huq sent out the first announcement. The IEC has taken care of basic booth arrangements such as tables and chairs. Bob Ross mentioned that Bob Haller is prepared to pick up the booth wherever it is shipped to and take it to the conference center. We also need to arrange for an LCD projector on site from Cadence or SiSoft. - Asian IBIS Summit Bob Ross reported that 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. Bob said that the first announcement has gone out. The steering committee is headed by Jiang Xiang Zhong of Huawei. Sigrity and Zuken have been added as sponsors, joining Huawei, Cadence, Mentor, and SiSoft as financial sponsors. The deadline for presentations is set to be one month in advance. Bob will be collecting all the signup information. 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 MACRO MODELING COMMITTEE Arpad Muranyi, following up from the report at the June 14, 2005 IBIS Summit Meeting, reported that a provisional IBIS Macro Modeling Committee is meeting weekly. Arpad and Bob Ross requested that this provisional group become an official task group of the IBIS Open Forum. Arpad said that the goal of the committee is to write a standard *-AMS library of basic SPICE building blocks for use in macro modeling. This idea is based on Donald Telian's macro modeling proposal, but uses the *-AMS languages for netlisting the macro models together with the proposed standard library building blocks. The standard library would be written in such a way that tools which don't have the capability of interpreting *-AMS equations could substitute the building blocks of the standard library with their corresponding native elements and still be able to simulate the macro models. This work would also pave the way for better acceptance of AMS languages. Bob asked if there was a committee chair. Arpad stated that there was no official chair, but he agreed to serve as the main contact for reporting to the IBIS Committee. Meetings are scheduled for Tuesdays at noon PST. A new website exists and contains documents, minutes, and mailing list information: http://www.sisoft.com/ibis-macro/ While EDA participants are encouraged to become involved, the participation is open to the IBIS community. Michael Mirmak will inform the GEIA of the formation of the committee. IBIS QUALITY COMMITTEE Bob Ross reported that at the August 2 meeting, they worked on BUG90 that introduces a caution flag in the parser. The next meeting is September 6. The committee will probably make a presentation for DesignCon East. The link to the quality committee checklist is at: http://www.eda.org/pub/ibis/quality_wip/ IBIS MODEL REVIEW COMMITTEE No update. FUTURES AND COOKBOOK COMMITTEES Michael Mirmak reported that there were meetings of both committees yesterday. Most of the meeting was BIRD95 discussion. Lance Wang presented some data related to BIRD95. The cookbook is now on its fourth draft, with a fifth draft being prepared for release next week. This draft is posted with new information about clamp tables for on-die terminations. A vote will be scheduled for approval of the cookbook at the August 26 teleconference meeting. Recent committee material is stored at: http://www.ibis-information.org/futures/ Draft 5 of the cookbook will be available at the following url for review: http://www.eda.org/ibis/cookbook/ibis-cookbook-review-draft5.pdf NEW ADMINISTRATIVE ISSUES None. BIRD99.1: AMS LANGUAGE VERSIONS Arpad Muranyi has not received any comments or questions recently. BIRD99.1 removed reference to "or later" with reference to the spice language. This BIRD revises the specification to change mention of support for a specific AMS language to support of the latest officially approved version of the language. Itzik Peleg began discussion about how a model creator can know what version of the AMS language they can use that will be supported. A vote was called for to approve BIRD99.1 and include it in the next version of the specification. The vote passed with the following vote tally: Cadence - abstain Cisco - yes Intel - yes Marvell - no Mentor - abstain Micron - yes Siemens - abstain Sigrity - abstain Teraspeed - yes Texas Instruments - abstain Michael Mirmak planned to see if there were any issues with approval of the BIRD due to the number of abstentions. BIRD95.6: POWER INTEGRITY ANALYSIS USING IBIS Syed Huq summarized that this BIRD adds I vs. T tables for power supply analysis. Bob Ross mentioned there were only editorial changes in BIRD95.6 over BIRD95.5 and no technical changes. Itzik Peleg asked about inclusion of the [Requiv], [Cequiv], and [Lequiv] keywords that were in BIRD95.3. Syed said that there were existing ways of implementing these parameters with current IBIS language such as with the [Series] keywords, so it was removed from the BIRD to allow flexibility in modeling the power supply impedance. Syed said that techniques to model power supply impedance would be described in a future revision to the Cookbook. Bob mentioned that the ICM specification allows for very complex descriptions of the power supply impedance, and once linkage is defined between ICM and IBIS, this will be an option. Michael Mirmak mentioned that at the Futures committee discussion, there was concern that not enough test cases had been investigated. Ian Dodd said that perhaps a publicly available model should be used for a case study. John Angulo said that progress could be made very quickly if Cisco can do a quick analysis on the model used by Cadence. In Cadence's study, it showed poor modeling results with BIRD95.6. Lance Wang said that anyone who would like the model simply needs to email him with the request. Lance also stated on Cadence's behalf that Cisco’s BIRD95 contributions and efforts need to be well recognized and highly appreciated, especially Zhiping Yang’s technical advice during Cadence’s test period. A call for vote was delayed to allow for more work to be done. Syed Huq has requested more active participation from EDA vendors in Futures meetings for BIRD95.6. A Futures committee discussion to go over more correlation study results will be planned for next week. The Cadence study presented at the last Futures committee meeting can be found at the following link: http://www.eda.org/pub/ibis/futures/BIRD95Tests_Aug42005_IBIS_Future.pdf BIRD94.2: CLARIFICATIONS ON [DIFF PIN] PARAMETERS Arpad Muranyi reported that BIRD94.2 is ready for approval vote at the next meeting. BIRD97.2: GATE MODULATION EFFECT No discussion. BIRD98: GATE MODULATION EFFECT (TABLE FORMAT) See BIRD97.2 for discussion related to BIRD98. IBISCHK4 BUG STATUS Michael Mirmak reported that there are three new BUGs filed against the parser. BUG88 is related to compilation of the code for Linux. The BUG is classified as moderate, medium, and open. Michael asked John Angulo to look into this BUG. BUG89 was filed by Shangli Wu of Cadence. This BUG relates to a complaint by the parser of the wrong illegal keyword when the parser checks an EBD file. This BUG is classified as moderate, medium, and open. BUG90 was filed by Bob Haller on behalf of the IBIS Quality Committee. This BUG proposes to add a new category of warning type called caution. The first caution statement would relate to a Vmeas level being outside of the Vinh/Vinl levels. This BUG is classified as an enhancement, low, and open. Michael, on a request from Bob, plans to compile a list of the open BUGs and proposals for all the fixes. ICMCHK1 BUG STATUS No new BUGs have been reported. NEW TECHNICAL ISSUES None. NEXT MEETING The next IBIS Open Forum teleconference will be held August 26, 2005 from 8:00 AM to 10:00 AM US Pacific Time. Votes are scheduled for BIRD94.2, BIRD95.6, and approval of draft 5 of the cookbook. ============================================================================ 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.
