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 1.0 specifications. No patents were declared. MEMBERSHIP UPDATE AND TREASURER'S REPORT Michael Mirmak reported 21 confirmed memberships for 2005 with three additional organizations having committed to pay within the next month. One member has declined renewal for 2005. Payment was confirmed from Silego, so they are officially a new member now. The GEIA has not yet received the 2004 year-end report from its financial subcontractor. REVIEW OF MINUTES AND ARS Michael Mirmak reviewed the minutes of the February 18, 2005 IBIS Open Forum teleconference. Silego had been noted as missing its representatives's name; this will be corrected. The minutes of the meeting were approved with the noted editorial change. PRESS AND WEB PAGE UPDATES Syed Huq reported that recent updates were made on the roster page, including an update to IBM's entry and the removal of member designation from one company. Further, Actel, ICS, and Silego logos were added to the virtual poster, while one company's logo was removed. NEW MODELS AVAILABLE, LIBRARY UPDATE Lance Wang reported that there has been no new model library activity. An update of the library pages is underway and will be completed and available for comment at the next meeting. MISCELLANY/ANNOUNCEMENTS Michael Mirmak noted that he will be leaving the US for an extended period starting March 21. From March 21 through 25, he will be attending events surrounding the JEITA IBIS Conference. After March 25, he will be on sabbatical in a variety of locations and will be out of regular contact until Monday, May 23. Syed Huq will run the Open Forum teleconferences. Most financial and summit arrangement issues will be completed before Michael leaves. OPENS FOR NEW ISSUES No opens were raised. MAILING LIST ADMINISTRATION Bob Ross noted no new problems or announcements. INTERNATIONAL/EXTERNAL PROGRESS Bob Ross observed that an EMC professional conference is being scheduled for the end of November in Munich that will likely attract participation from familiar members of the IBIS community. More information will be made available in future teleconferences. Arpad Muranyi attended the VHDL-AMS working group meeting on Wednesday, March 9 at DATE and can give an update at the next teleconference. SUMMITS - DATE European IBIS Summit, March 11, 2005, Munich, Germany Katja Koller and Arpad Muranyi reported that the DATE IBIS Summit was highly successful, with between 25 and 28 attendees. Significant new material on BIRD95 and related proposals was presented. Bob Ross is posting the remaining presentations to the website. - JEITA IBIS Event - Japan, March 24, 2005, Tokyo, Japan Michael Mirmak reported that all arrangements for the JEITA IBIS event have been completed. Those interested in further information can contact Michael Mirmak with questions. - DAC IBIS Summit, Tuesday, June 14, 2005, Annaheim, CA Bob Ross reported that DAC will be held in Annaheim, California from June 13-17. A room needs to be reserved for 30-35 people. Tuesday, June 14 would be the Summit. John Angulo reported that Mentor will be reserving rooms, but that an IBIS summit request has not yet been filed. John also inquired about the possibility of reserving booth space. This will be discussed further offline. - DesignCon East IBIS Summit Bob Haller reported that DesignCon East has been moved to a location in western Massachusetts -- Worcester -- but will still take place from September 19-21. Bob Ross proposed dropping summit plans for PCB East in October in favor of DesignCon East. Michael Mirmak noted that a co-sponsorship arrangement had been negotiated for 2004 and had worked well, plus the IEC has already approached the Open Forum regarding participation this year. Booth transport would not be needed, if plaques and other materials could be sent to the venue in advance. A backdrop could be used in place of a booth. Sponsorship opportunities for DAC are still available, with sponsors receiving free mentions in the minutes, agenda, and other announcements. IBIS ANSI BALLOT STATUS Michael Mirmak noted that ANSI balloting of IBIS 3.2 continues through the GEIA. PINS forms have been filed by Randy Wolff for IBIS and ICM for future revisions, should the team wish to ballot updates to these documents. S2IBIS3 STATUS Bob Ross, Lynne Green, Syed Huq and Michael Mirmak reported on a number of S2IBIS issues. First, some compilation issues were noted for Linux in the S2IBIS2 distribution posted on the IBIS website. These have been corrected. One issue, regarding spaces in numerical multipliers, still remains. The team will discuss offline how this can be resolved. A final release of S2IBIS3 has been issued by Ambrish Varma, replacing the previous beta. S2IBIS3 V1.0 executables can be downloaded from: http://www.ece.ncsu.edu/erl/ibis/s2ibis3/s2ibis3.htm IBIS VERSION 4.1 PARSER STATUS Bob Ross reported that all of the parser contract requirements have been met and that no further improvements can be included outside of the BIRD process. Issues remain at the specification level regarding links to ICM and the legality of "dangling" IBIS power ports. Final code has been completed and is ready for distribution. A motion was made and seconded to vote on approving the IBIS 4.1 parser. The voting members and results are as follows: Cadence - yes Cisco - yes Intel - yes LSI Logic - yes Mentor Graphics - yes Samtec - yes Siemens - yes SiSoft - yes Teraspeed - yes The vote passed unanimously. Michael will distribute the source code to the parser licensees. Bob and Michael will post executables for a variety of formats to the IBIS web site. Guy de Burgh has offered to assist in code compilation. The GEIA will be instructed to pay the final invoice on the parser to the developer. ICM SPECIFICATION AND PARSER STATUS Michael Mirmak announced the first "reading," or call for comment, on the draft ICM 1.1 specification. Bob Ross reported four editorial comments on spacing of paragraphs, missing terms, revision history notes, and extra text in an example. Michael also noted an issue with usage of the word "real." These will be addressed through an updated draft to be released before the next Open Forum meeting. IBIS QUALITY COMMITTEE Robert Haller reported, through Michael Mirmak, on the Committee's status. The most recent meeting was held March 8. Review continues of quality checks not already in the parser. The goal is to eventually submit these new checks as parser bugs. Mike LaBonte confirmed this goal, and the team agreed that parser changes can be considered through either the BIRD or BUG process. IBIS MODEL REVIEW COMMITTEE Lynne Green reported that three organizations, AMCC, Freescale and Toshiba have provided models for review through the committee. The models were checked and feedback distributed to the originators. FUTURES AND COOKBOOK COMMITTEES Michael Mirmak reported that the Futures committee met on March 10, while the Cookbook committee meeting was postponed. Extensive discussion took place on both BIRD95.2 as well as a new proposal from Michael on ICM-IBIS links. Bob Ross made a few comments on the ICM link proposal, suggesting that limits on the links should not be necessary; both specifications are self-consistent individually and permit complete descriptions of their end-points. Michael partially agreed, but suggested further discussion was needed in the Futures committee. Recent committee material is stored at: http://www.ibis-information.org/futures/ NEW ADMINISTRATIVE ISSUES None to report. BIRD95.2: POWER INTEGRITY ANALYSIS USING IBIS Syed Huq reviewed the latest version of BIRD95. The new text only addresses I/O rail variations; core power plus ICM and ICEM links have been moved to BIRDs as yet unfiled. Several comments on BIRD95.2 will be addressed in a separate BIRD97 to be introduced later. New L, R, C and G parameters for Z_VDDQ have been introduced to support impedance modeling of the rail to rail path in the absence of ICM data. Syed thanked Bob Ross for his contributions and comments. John Angulo suggested Z_VDDQ be made into its own keyword, and both John and Itzik Peleg suggested that the BIRD clarify that Z_VDDQ does not include on-die power distribution network details. Arpad Muranyi suggested that C_comp be differentiated from C_bp, perhaps even in a Cookbook description. Itzik also pointed out several typographical errors in BIRD diagrams. All of these will be fixed. Michael Mirmak inquired whether the BIRD conflicts with BIRD74.6 on EMI Parameters from Guy de Burgh. Guy suggested that there was no conflict, as the EMI parameters refer to the entire component, while BIRD95.2 addresses buffer-level effects. Bob Ross mentioned that he plans to move the set of subparameters to a different location under [Model] to avoid repeating them for each [Composite Current] call. Also, Itzik proposed that the Z_zvddq impedance subparameters include min and max values, and it was agreed to do this. BIRD94.1: CLARIFICATIONS ON [DIFF PIN] PARAMETERS Arpad Muranyi very briefly noted that several proposed requirements had been removed from BIRD94, leaving only corrections to language and examples in the text. No other comments were made on the BIRD. BIRD97: GATE MODULATION EFFECT Arpad Muranyi briefly introduced BIRD97, which adds new subparameters to describe modulation of I-V tables due to power supply variations. Arpad suggested the current BIRD assumes linear variation in supply rail voltages, but that the DATE summit attendees proposed more complex relationships. Itzik Peleg mentioned a quadratic relationship set of coefficients. Arpad acknowledged this and mentioned tables showing variation as a function of voltage, as another possibility. Michael encouraged attendees to provide comments on the reflectors. IBISCHK4 BUG STATUS None to report. ICMCHK1 BUG STATUS None to report. NEW TECHNICAL ISSUES None. NEXT MEETING The JEITA IBIS Event will be held March 24, 2005 in Japan. No telephone bridge is available. The next IBIS Open Forum teleconference will be held April 1, 2005 from 8:00 AM to 10:00 AM US Pacific Time. The meeting will be chaired by Syed Huq. ============================================================================ 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.
