Apache's first exposure with IBIS was their NSPICE simulator that supports IBIS. Their companies simulators specialize in full chip power integrity. They are interested in working with IBIS on full solutions for chip, package and board power integrity. 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 revenue looks good so far. Membership is at 18 members. AMD, Cadence, and Hitachi are confirmed renewed now. Michael urged members to return renewals as soon as possible. REVIEW OF MINUTES AND ARS Michael Mirmak reviewed the minutes of the March 31, 2006 IBIS Open Forum teleconference. The minutes were approved without changes. PRESS AND WEB PAGE UPDATES Syed Huq reported no updates. MAILING LIST ADMINISTRATION Bob Ross reported that things are normal. He blocked a spammer with the help of Mike Labonte. NEW MODELS AVAILABLE, LIBRARY UPDATE Lance Wang reported that he is working on checking all links and adding ICM links on a new webpage. MISCELLANY/ANNOUNCEMENTS None. OPENS FOR NEW ISSUES None. INTERNATIONAL/EXTERNAL PROGRESS Bob Ross had no new report. Bob mentioned that the 10th IEEE workshop on Signal Propagation on Interconnects (SPI) is May 9-12 in Berlin, Germany. There will be a paper about developing an IBIS-like specification for lasers used in optical interconnect. For more information on SPI can be found at the following link: http://www.spi.uni-hannover.de/ EIA/ANSI APPROVAL ACTIVITIES No update. Randy Wolff confirmed that a PINS document has been filed with GEIA, so as soon as the IBIS Open Forum votes on release of the IBIS 4.2 specification, it will be ready to start the GEIA balloting process for standardization. SUMMITS - DAC DAC will be held July 24-28, 2006 in San Francisco. The Summit is planned for July 25. John Angulo has the AR to make room reservations. Michael Mirmak asked about finding out who has planned presentations. - Summits in Asia Bob Ross reported that the plan is to hold two summits, one in Shanghai and one in Tokyo. They will be held either the same week or a week apart, so that people can attend both summits on the same trip. He is working on scheduling the dates. Late October looks like the timeframe. In China, money from last years summit will be used towards part of the sponsorship this year. In Japan, the tentative plan is to meet with JEITA and host an opening meeting most of the day and a private IBIS/JEITA meeting late in the day. They are determining whether to host it at JEITA headquarters for 60 people or go to an outside hotel to support a larger attendance. Michael Mirmak questioned whether the meeting would be too short with having the three-hour private JEITA/IBIS meeting. - DATE 2007 Bob Ross discussed that DATE 2007 will be held in Nice, France. We will need to investigate either finding local support to sponsor the summit in Nice or hold it in Munich, Germany instead. Sponsorship opportunities for DAC and other summits are available, with sponsors receiving free mentions in the minutes, agenda, and other announcements. IBIS QUALITY COMMITTEE Mike Labonte reported that at the last meeting, there was continued discussion of revamping the level rating for ease of use. they also discussed BUG94. Mike plans to update this BUG and resubmit it to the committee for review for the next Open Forum meeting. The next meeting is April 25. Mike also mentioned that Roy Leventhal joined the last meeting. The link to the quality committee checklist is at: http://www.ibis-information.org/quality_wip/ IBIS MODEL REVIEW COMMITTEE No update. FUTURES AND COOKBOOK COMMITTEES Michael Mirmak reported that the Cookbook committee has not met formally in awhile. They are awaiting tweaks to the language on V-t curves before more discussion takes place. There have been meetings of the Futures committee every week. At the last meeting, they talked about a potential encryption standard for [External Model]s and [External Circuit]s. VHDL-AMS and Verilog-AMS management committees may be the best place to drive this. Arpad Muranyi discussed having an IBIS representative attend the VHDL-AMS and Verilog-AMS meetings to make proposals. Ian Dodd expressed his interest in working on encryption standards as well. Recent committee material is stored at: http://www.ibis-information.org/futures/ The Cookbook version 4 is stored at: http://www.ibis-information.org/ibis/cookbook/cookbook-v4.pdf MACROMODELING LIBRARY COMMITTEE Arpad Muranyi reported that the issue has arisen that macromodels may not be capable of modeling some of the more complicated new buffer designs. The committee is looking at describing new devices in AMS, but this will lose the SPICE compatibility. This will probably happen in a phase two library of advanced elements. Michael Mirmak suggested looking at other standardized libraries for guidance. No technical changes have been made to the library recently. Mike Labonte mentioned that the encryption topic has come up several times in the macromodeling committee. Committee material can be found at the following url: http://www.ibis-information.org/macromodel_wip/ IBIS 4.2 DRAFT Michael Mirmak introduced the third reading of the IBIS 4.2 specification draft. He issued a call for comment. Bob Ross said that the revision 1 text version has a lot of changes to it. One major change in the works is cleaning up how units are specified in the package and EBD sections. Some other issues still need to be discussed, so it looks likely that the June 2 meeting will be used for calling for a vote to give time to make all the changes and discuss them one more time. The latest IBIS 4.2 draft is available at the following url: http://eda.org/pub/ibis/ver4.2_wip/rev_1/ver4_2_1.txt NEW ISSUES None. BIRD97.2: GATE MODULATION EFFECT Arpad Muranyi had no update. He plans to run some experiments soon and have a proposal ready for the DAC meeting. BIRD98: GATE MODULATION EFFECT (TABLE FORMAT) See BIRD97.2 for discussion related to BIRD98. BIRD103: [MODEL SPEC] DDR2 OVERSHOOT/UNDERSHOOT PARAMETERS Randy Wolff introduced the BIRD. This BIRD proposes adding four new parameters to the IBIS specification under [Model Spec] that will give EDA software the conditions necessary to check for overshoot violations on DDR2 SDRAM devices and issue warnings. The JEDEC DDR2 SDRAM Specification (JESD79-2A) specifies AC overshoot in terms of a maximum area above or below specific voltage thresholds. A maximum overshoot/undershoot amplitude is also defined. The parameters available for [Model Spec] do not provide a way to check for violations of this overshoot/undershoot condition as calculated by area. The dynamic overshoot/undershoot parameters can specify time and maximum voltage, but these are not adequate to define an area in terms of V-s. Michael Mirmak asked if these new parameters could be applied to other technologies. Randy replied that it could be applied to DDR3, but he did not know about any other technologies. Eckhard Lenski was confused on area being shown as a triangle in the JEDEC specification. Randy agreed to add some more descriptive text to the BIRD to clarify this and reissue the BIRD as BIRD103.1. IBISCHK4 BUG STATUS John Angulo looked at the time it would take to implement Analog-only checking for the IBIS 4.2 parser. It looks to be 1-2 days of work. Michael Mirmak is investigating this for length of file names and model names parser changes. The goal is to fix as many BUGs as possible with the IBIS 4.2 release, but many BUGs will have to wait until a 5.0 parser. There are at least 11 open BUG reports that need to be resolved. ICMCHK1 BUG STATUS Michael Mirmak mentioned that no new BUGs have been filed. There has been talk of looking at the lengths on RLC parameters. NEW TECHNICAL ISSUES None. NEXT MEETING The next IBIS Open Forum teleconference will be held May 12, 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.
