He is a Senior Software developer and is attending in place of other usual participants. 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 three new members for this year. Agilent has joined for the first time. Apache DA and Toshiba are new joins as well. There have been 19 regular member renewals, so there are 22 members so far. Other renewals are in progress. We are in position to have a large membership this year. Michael reminded companies that they will be dropped from the membership list if they have not renewed before the DAC conference IBIS summit. We have $17,500 in the treasury. We are also working on getting a new parser payment. REVIEW OF MINUTES AND ARS Michael Mirmak reviewed the minutes of the May 12, 2006 IBIS Open Forum teleconference. The minutes were approved without changes. PRESS AND WEB PAGE UPDATES Michael Mirmak reported that there were minor updates to add the new members to the membership roster. MAILING LIST ADMINISTRATION Bob Ross reported that everything is working normally with the mailing lists. Temporarily, the eda.org domain is not working, and that issue is being resolved. NEW MODELS AVAILABLE, LIBRARY UPDATE Lance Wang reported that he is planning to reconstruct the model webpage. There are no ICM models to link to the page, so Lance asked that any companies with ICM models available forward him links to the models. MISCELLANY/ANNOUNCEMENTS None. OPENS FOR NEW ISSUES None. INTERNATIONAL/EXTERNAL PROGRESS Bob Ross had no report on the IEEE workshop on Signal Propagation on Interconnects (SPI) conference. He mentioned that 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/ Bob also mentioned the Electrical Performance of Electronic Packaging (EPEP) conference 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/ Arpad Muranyi attended SPI and saw presentations from optical research people. One was developing an IBIS-like specification for lasers used in optical interconnects. Arpad found that this idea was very early in the development stage. The presenters felt that adding their requirements to IBIS would make sense, because they did not need very many parameters to describe their drivers. Michael Mirmak suggested that we invite the authors to attend a Future's group meeting. Arpad said that the main message is that the optical world should come towards the electronic world. EDA vendors should embrace bringing optical simulation capabilities into their tools. EIA/ANSI APPROVAL ACTIVITIES Randy Wolff mentioned that he will send the IBIS 4.2 specification to the GEIA to begin the GEIA/ANSI balloting process as soon as the IBIS Open Forum votes on its release today. The balloting process will take about 30 days. SUMMITS - DAC DAC will be held July 24-28, 2006 in San Francisco. The Summit is planned for July 25. The first "call for papers" was sent out by Syed Huq. Mentor facilities is looking to reserve a room for about 30 people. John Angulo suggested we lower this number if possible for better pricing possibilities, and we need to decide how to handle lunch arrangements. It was decided to arrange a room for 30, as attendance will likely be this high. Several papers are already planned. - Summits in Asia Bob Ross reported that summit planning is progressing well. We might need to consider changing the Japan summit from October 24 to October 31 to avoid conflicting with the EPEP conference. The China summit date is finalized as Friday, October 27 in Shanghai, so room arrangements can move Sponsorship opportunities for DAC and the Asian IBIS summits are available, with sponsors receiving free mentions in the minutes, agenda, and other announcements. IBIS QUALITY COMMITTEE Bob Ross reported that they are re-looking at the checklist to make it more sensible. There are 94 items on the checklist. Also, they are looking at changing the classification system. There is a meeting next Tuesday. The link to the quality committee checklist is at: http://www.vhdl.org/pub/ibis/quality_wip/ IBIS MODEL REVIEW COMMITTEE Lynne Green had a model come in yesterday that is being reviewed. She encouraged others to send in models. FUTURES AND COOKBOOK COMMITTEES Michael Mirmak reported that an update on Cookbook changes being proposed by Lynne Green was discussed at the last meeting. An incremental Cookbook update will probably be released shortly. Arpad Muranyi presented an update on BIRD97/98 showing the addition of new components that improve the quality of the model. He plans to present these ideas at the DAC conference. Recent committee material is stored at: http://www.vhdl.org/pub/ibis/futures/ The Cookbook version 4 is stored at: http://www.vhdl.org/pub/ibis/cookbook/cookbook-v4.pdf MACROMODELING LIBRARY COMMITTEE Arpad Muranyi reported that they discussed at the last meeting simulation techniques in high speed, multi-tap buffer environments and what will be required to model them. They also discussed what is being done in Matlab and other tools currently. Committee material can be found at the following url: http://www.vhdl.org/pub/ibis/macromodel_wip/ IBIS 4.2 DRAFT Michael Mirmak stated that the IBIS 4.2 specification is scheduled for a vote today. He issued a call for comment. Michael mentioned that Jon Powell has agreed to make some final changes to the IBISCHK code to update it to work with the IBIS 4.2 specification. There was a motion for vote to approve the IBIS 4.2 specification and for release of it to GEIA to begin the GEIA/ANSI approval process. The vote passed with the following vote tally: Agilent - abstain AMD - yes Cadence - yes Cisco - yes Green - yes Intel - yes Mentor - yes Micron - yes Siemens - yes Sisoft - yes Synopsys - yes Teraspeed - yes The official vote is recorded as 12 yes, 0 no, 1 abstain. [After the meeting we note that LSI Logic e-mailed a yes vote.] The final IBIS 4.2 draft is available at the following url: http://vhdl.org/pub/ibis/ver4.2/ver4_2.txt NEW ISSUES None. BIRD97.2: GATE MODULATION EFFECT Arpad Muranyi reported that he has run many experiments recently. He discovered that while only C_comp is in current IBIS models, there are many other capacitances that exist in the real buffers that impact the gate modulation effect. These capacitances cause RC effects that delay the response of current on the output when voltage changes on the gate of the driver transistors. He is working to determine how to find values of capacitance and resistance that are needed to model these effects. Arpad gave a presentation at the Future's meeting yesterday, and this presentation can be found at the following link: http://www.vhdl.org/pub/ibis/futures/Quiet_line_experiment_2.pdf Bob Ross suggested that there may be ways to use the series R and C elements to describe some of these parasitics. Michael Mirmak mentioned that addition of extra C elements may mess up the C_comp compensation algorithms associated with V-t curves. More simulations work will be done to help fully understand the problem. BIRD98: GATE MODULATION EFFECT (TABLE FORMAT) See BIRD97.2 for discussion related to BIRD98. BIRD103.1: [MODEL SPEC] DDR2 OVERSHOOT/UNDERSHOOT PARAMETERS Randy Wolff mentioned that no changes had been made to the BIRD since the last teleconference. The only change to the BIRD before that was a sentence added to clarify that the overshoot area is true are-under-the-curve and not an arbitrary triangular area. A vote was called to have this BIRD approved for addition to the next version of the IBIS specification. The vote passed with the following vote tally: AMD - yes Cadence - yes Cisco - yes Green - yes Intel - yes Mentor - yes Micron - yes Siemens - yes Sisoft - yes Teraspeed - yes The official vote is recorded as 11 yes, 0 no, 0 abstain. [After the meeting we note that LSI Logic e-mailed a yes vote.] IBISCHK4 BUG STATUS Michael Mirmak reported that there are 10 open BUGs, but BUG86, BUG88 and BUG89 will be closed with the new parser. An 11th BUG, BUG85, has been closed. It was closed earlier but not recorded properly. We may ask Jon Powell to address BUG93 in the new parser, as this one is a severe classification. ICMCHK1 BUG STATUS Lynne Green mentioned that Kelly Green will not be able to provide much support going forward for any further ICMCHK work. NEW TECHNICAL ISSUES None. NEXT MEETING The next IBIS Open Forum teleconference will be held June 23, 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.
