CALL FOR PATENTS Michael Mirmak called for any patents or pending patents related to the IBIS Version 3.2, 4.0, 4.1, 4.2, or ICM 1.1 specifications. No patents were declared. MEMBERSHIP UPDATE AND TREASURER'S REPORT Michael Mirmak reported that we have two recent updates from GEIA. We have officially 24 members now. The budget is on the positive side. We have not received a full billing for the DAC summit yet. Bob Ross reported that the total is now 26 based on a new member IO Methodology and also a renewal that was just received. He expects that we will get over 30 members this year based on renewals in progress. REVIEW OF MINUTES AND ARS Michael Mirmak reviewed the minutes of the June 1, 2007 IBIS Open Forum teleconference and the June 5, 2007 IBIS Open Forum summit meeting. Bob Ross noted that ZTE should be listed in the members section in both sets of minutes. Also, ZTE was incorrectly listed both as a voting member and also as an “other participant” in the July 5 minutes. The minutes were approved with the noted changes. WEB PAGE UPDATES Michael Mirmak reported that the listing of DATE summit presentations on the website was fixed. Also, the DAC presentations are now listed. MAILING LIST ADMINISTRATION Bob Ross reported that the list is running normally. NEW MODELS AVAILABLE, LIBRARY UPDATE Lance Wang has completed requests from Agilent to update some links. PRESS UPDATE None. MISCELLANY/ANNOUNCEMENTS None. OPENS FOR NEW ISSUES Bob Ross requested a discussion of BUG98 and the caution flag, both related to the parser. INTERNATIONAL/EXTERNAL PROGRESS Several upcoming conferences of interest to IBIS members include: SSP, the IEEE Statistical Signal Processing Workshop held August 26-29, 2007 in Madison, WI. The deadline for paper submissions has passed. More information can be found at: http://ssp07.org/ EMC 2007, the IEEE International Symposium on Electromagnetic Compatibility held July 8-13, 2007 in Honolulu, Hawaii. More information can be found at: http://www.emc2007.org/index.htm Bob Ross noted that presentations from the SPI conference are uploaded on the website: http://www.spi.uni-hannover.de/ IEC APPROVAL ACTIVITIES Michael Mirmak mentioned that he received a note from Victor Berman, who is interested in a teleconference with the board or participating in an open forum meeting to discuss how DASC and IBIS can work together. SUMMITS - DAC Summary DAC was held June 4-8, 2007 in San Diego, California. Tuesday, June 5 was the IBIS summit. Michael Mirmak summarized that 25 people from 19 organizations attended. There were good discussions, with quality presentations. There were a number of topics related to the quality of IBIS models, as well as ATM, Spice, and interconnect modeling activities. - Asian IBIS Summit China Planning Tuesday, September 11 will be the China meeting in Beijing. The Park Plaza Science Park hotel is reserved. Bob Ross and Lance Wang are contacts for signing up. The first call for papers for went out, and the second announcement will go out next week. Official sponsors so far of the China summit are Huawei Technologies, Agilent, Ansoft, Cadence, Intel, Mentor Graphics, Sigrity, SiSoft, Synopsys and ZTE Corporation. Bob mentioned that he is getting some commitments for presentations already. - Asian IBIS Summit Japan Planning Friday, September 14 will be the Tokyo meeting at JEITA headquarters. Two new sponsors are ATE Service Corporation and Cybernet Systems. The other official sponsor of the Japan summit is JEITA with others to be determined. The first announcement will go out in about a week. Bob is the main contact for this event. Sponsorship opportunities for the Asian IBIS summits are available, with sponsors receiving free mentions in the minutes, agenda, and other announcements. Contact the IBIS Board for further details. Michael Mirmak mentioned that he was asked from some companies in Taiwan to potentially hold a summit in Taiwan, Singapore or Malaysia. It is difficult for companies in Taiwan to get visas to attend the China summit. Michael plans to discuss this in more detail at the next meeting. Bob mentioned that any extra Asian IBIS summit would need to be scheduled within the same timeframe as the other two established summits. IBIS QUALITY TASK GROUP David Banas reported that they finished discussing through check 3.4.3 of the Quality report. They will be discussing thresholds at the next meeting. The link to the quality task group checklist is at: http://www.eda-stds.org/ibis/quality_wip/ IBIS MODEL REVIEW TASK GROUP No update. ADVANCED TECHNOLOGY MODELING TASK GROUP Arpad Muranyi reported that there have been no meetings since the summit. The BIRD drafting group has continued meeting and will have an update to present at the meeting next week. Task group material can be found at: http://www.eda-stds.org/ibis/macromodel_wip/ AD HOC TASK GROUPS (INTERCONNECT) Michael Mirmak reported that the group finished discussing Touchstone and will be discussing IIRD9 in the next two meetings, then moving onto IBIS to ICM links after that. Task group material including the Touchstone2 draft specification can be found at: http://www.eda.org/ibis/adhoc/interconnect/ NEW ISSUES None. IBISCHK4 BUG STATUS Bob Ross got a release of the 4.2.2 parser from Atul Agarwal and distributed to the board and a few other people to review. He is waiting for some quick feedback on the DOS executable. Randy Wolff mentioned that he had checked a DDR3 model with the parser, and it appeared to be checking the [Receiver Thresholds] and combinations of I-V curve tables properly. Bob mentioned the new caution flag option of the parser. Caution messages would be issued with this option, but currently the parser will not issue cautions unless the flag is specified. At least one EDA vendor has said that they would like to have this as the default so that the caution messages can be added as an option in the GUI. Michael Mirmak said that we need to come up longer term with a parser specification to describe changes such as this and why certain changes are made between releases of the parser. Michael will schedule a more lengthy discussion in the next meeting. Members were asked if they had any issues with beginning parser release as-is. We will begin the release process soon. Bob reported BUG98. Zuken found two coding mistakes, and the first one was fixed. The second one relates to use of the stack in the C code, and the recommendation is to change stack pointers. BUG98 will be classified as annoying severity, low priority, and open. ICMCHK1 BUG STATUS No update. BIRD98.1: GATE MODULATION EFFECT (TABLE MODEL) Bob Ross is planning to work with STMicroelectronics on the next revision. He did issue a chopped version to STM where he rearranged paragraphs to group related information together and remove redundant information. He also updated the data tables to fix pullup table referencing to be VDD relative. He has also asked for clarification of some other parameters. PROPOSED TOUCHSTONE2 SPECIFICATION INTRODUCTION Michael Mirmak introduced a proposal to update the Touchstone specification to version 2.0 without invalidating any version 1.0 files. Version 2.0 adds keywords in IBIS style to remove limits on the number of ports as well as support different reference impedances for different ports. There was discussion about having complex reference impedances, but this was rejected. There are some legal issues still to deal with related to the Touchstone name. Arpad Muranyi asked about support from vendors for the new specification. Michael said that support for developing the new specification has been good, especially from Agilent, the original developer of Touchstone. Michael also mentioned that we need to decide if developing a parser is necessary and/or desirable. Michael is bringing this specification to the Open Forum for further discussion leading into an approval vote when appropriate. The specification can be found at the following link: http://www.eda.org/ibis/adhoc/interconnect/touchstone_spec2_draft8.pdf NEW TECHNICAL ISSUES None. OPEN ISSUES Bob Ross asked Michael Mirmak while traveling to Asia to confirm with several companies if membership payments have been sent and also to check on summit planning activities. NEXT MEETING The next IBIS Open Forum teleconference will be held July 13, 2007 from 8:00am to 10:00am 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 FM5-239 1900 Prairie City Rd.
