He has recently transferred from working on Cadence Spectre to working with Cadence tools using IBIS. 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 that we have 27 members as of the last update from GEIA. Two or three memberships have not been confirmed yet. Syed Huq mentioned that we are talking to a few other potential new members. Michael said that we are in need of one or two IBISCHK4 parser purchasers. REVIEW OF MINUTES AND ARS Michael Mirmak reviewed the minutes of the May 13, 2005 IBIS Open Forum teleconference. The minutes of the meeting were approved without changes. PRESS AND WEB PAGE UPDATES Syed Huq reported that the events page and roster pages were updated. He is working on updating broken links as well. NEW MODELS AVAILABLE, LIBRARY UPDATE No update. MISCELLANY/ANNOUNCEMENTS Michael Mirmak thanked several members for their help while he was away on sabbatical. OPENS FOR NEW ISSUES None. MAILING LIST ADMINISTRATION Bob Ross reported that everything is running normally. He has noticed people sending binary files on the reflector. Even though we do not filter out binary attachments, it is our policy to discourage such messages for achiving space and security reasons. Michael Mirmak asked if there was a way to support these files. Bob will look into this. INTERNATIONAL/EXTERNAL PROGRESS Bob Ross discussed some pending standards under consideration by the International Electrotechnical Commission (IEC) under the technical committee TC47. 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). 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). Some of this activity was moved from TC93 where IBIS used to reside. The documents are available for technical review from Bob. Bob mentioned that because of our related IBIS standard and actual involvement, we are the appropriate committee to review and comment on these documents. Michael Mirmak reported that the IEEE 1076.1 committee which controls the AMS modeling languages has invited a presentation on IBIS to be presented at their committee meeting at DAC. Arpad Muranyi made a presentation to this committee previously. EIA/ANSI APPROVAL ACTIVITIES Randy Wolff reported that he contacted Chris Denham of GEIA to inquire about the current status of the IBIS 3.2 specification in the ANSI approval loop. Chris only confirmed that it is in the public review process. Randy was in the process of searching for more information on the ANSI website and took the AR to request further information from GEIA. SUMMITS - DAC IBIS Summit, Tuesday, June 14, 2005, Anaheim, CA DAC will be held in Anaheim, California from June 13-17, 2005. The IBIS Summit meeting will be held in the Anaheim Marriot. The room is Gold Key 1 and 2. We should have room for 30 attendees. Syed Huq reported that there are seven, possibly eight presentations confirmed with 19 confirmed attendees. He would like to send out the agenda on Monday. John Angulo mentioned that we have until next Wednesday to confirm the number of people for lunch. Michael Mirmak will be bringing a projector, laptop, etc. There will be no booth at DAC. Mentor and Cadence are co-sponsoring the summit. - DesignCon East IBIS Summit DesignCon East will be held in Worcester, Massachusetts from September 19-21, 2005. September 19 will be the IBIS Summit. IBIS will be an associate sponsor. Bob Ross reported that plans are proceeding. No contract has been signed yet. The IEC will provide a meeting room in the DCU conference center. There is a teleconference bridge planned for the summit. This may have to be paid for by the IBIS committee and costs about $150-$200. Lunch is provided as part of the Monday keynote speaker lunch speech. Cadence/Sisoft are co-sponsoring the event. Ian Dodd is coordinating the booth and will arrange for its transfer to Massachusetts. Local setup of the booth needs to be coordinated. - China Summit Bob Ross mentioned that very preliminary planning has begun. Plans are focusing on Shenzhen, China near Hong Kong in December. Many active Chinese and US based companies are there. It looks to be a large meeting. Sponsorship si planned from Huawei, Cadence, and Mentor as well as others. There are many financial logistics issues to work out. Sponsorship opportunities for DAC and DesignCon East are still available, with sponsors receiving free mentions in the minutes, agenda, and other announcements. IBIS VERSION 4.1 PARSER STATUS Bob Ross summarized the proposal to raise the parser price to $2500 per IBISCHK4 license. This new price will be in effect for all new parser purchasers. There was a call for vote on the $2500 parser license fee increase. The vote passed with the following vote tally: AMD - yes Cadence - abstain Cisco - yes Intel - yes Mentor Graphics - yes Micron - yes Siemens - yes Sigrity - yes Teraspeed - yes ICM SPECIFICATION AND PARSER STATUS The most current copy of the ICM 1.1 specification is available on the IBIS website. Michael Mirmak opened up the second official formal reading and comment period (of three). Bob Ross mentioned that some example dates within the specification need to be changed. IBIS QUALITY COMMITTEE Mike LaBonte reported that there has not been a recent meeting since the last IBIS Open Forum teleconference. There are open ARs doing some final review of the document. Bob Ross confirmed that the current URL on eda.org is not a permanent link. The next meeting is June 7. The link to the quality committee checklist is at: http://www.eda.org/pub/ibis/quality_wip/ IBIS MODEL REVIEW COMMITTEE Lynne Green reported that there have not been new models submitted since the last meeting. FUTURES AND COOKBOOK COMMITTEES Michael Mirmak reported that there were meetings of both committees yesterday. All the BIRDs being discussed in the Open Forum teleconference were addressed. There was discussion of where the current BIRDs should be, in IBIS 4.2 or 5.0. Lynne Green suggested announcing a cutoff date for BIRDs associated with IBIS 4.2. The latest copy of the cookbook was reviewed. The cookbook is essentially complete with just some editorial changes. An approval vote is expected within the next two or three Open Forum meetings. Recent committee material is stored at: http://www.ibis-information.org/futures/ S2IBIS3 STATUS Ambrish Varma reported no new update. He has continued to receive questions about the program, so he definitely sees people using the software. S2IBIS3 V1.0 executables can be downloaded from: http://www.ece.ncsu.edu/erl/ibis/s2ibis3/s2ibis3.htm NEW ADMINISTRATIVE ISSUES None to report. BIRD94.1: CLARIFICATIONS ON [DIFF PIN] PARAMETERS Arpad Muranyi reported that there are no recent changes to the BIRD. He is waiting for comments on the BIRD. BIRD 94.1 makes no functional changes to the specification. It makes editorial changes only. Bob Ross asked again about the meaning of NA in the BIRD. Arpad reiterated that NA to him means that a value is "Not Available". Arpad says the BIRD clarifies this. The BIRD will be scheduled for a vote at the next Open Forum meeting. Arpad would like this BIRD to be included in IBIS 4.2. BIRD95.5: POWER INTEGRITY ANALYSIS USING IBIS Syed Huq reported that presentations on this BIRD will be given at the DAC summit. Syed said that Zhiping from Cisco will share information on simulation with multiple switching buffers. There has been concern with this BIRD's ability to model SSO situations accurately. BIRD97.2: GATE MODULATION EFFECT Arpad Muranyi mentioned that the change from BIRD97.1 is to the equation that adds an extra component as requested by Katja Koller. Since BIRD97.2 and BIRD98 are related, further discussion on BIRD97 is in the BIRD98 section. BIRD98: GATE MODULATION EFFECT (TABLE FORMAT) Arpad Muranyi summarized this BIRD. It is very similar to BIRD97.2; however, the equation based format has been replaced with a table based method of reporting data. With this BIRD, the model maker would not have to fit data to an equation, so this would be much easier to work with. Arpad expects to vote down BIRD97.2 in favor of BIRD98. Michael Mirmak asked if some text would need to be added to the data derivation method section in the specification. Arpad believes that this language does exist in BIRD98, however it does not currently exist in BIRD 97.2. Bob Ross asked about references in the text that refer to positional requirements of the added keyword. Arpad mentioned that this needs to be explicitly stated, and also that BIRD95.5 needs to clean up language referring to where the keywords should be located within a [Model]. Bob asked where the term Ishort came from. Arpad said that this was originally called Isaturation, but he deemed this term non-technically accurate. Bob requested that the description contents of the BIRD be moved so as to shorten the length of the text that would be placed in the specification. Arpad expressed that he thought the text was important to include. This will be discussed more offline. It was mentioned that Antonio Girardi of STMicroelectronics would like to show some data on the gate modulation effect. His presentation will probably be scheduled during a Future's meeting. Arpad would like this BIRD to be included in the same version of IBIS as BIRD95.5. IBISCHK4 BUG STATUS Michael Mirmak reported that he believed all BUGs have been addressed with the latest release of the parser. Bob Ross mentioned that there are still four pending BUGs that have not been dealt with. ICMCHK1 BUG STATUS Michael Mirmak reported that one text block overflow related BUG was reported and fixed as of the latest parser release. NEW TECHNICAL ISSUES Arpad Muranyi mentioned that he will probably write a BIRD related to the AMS language extensions in IBIS. He would like to change the text that specifies compliance to a specific version of the Verilog-AMS and VHDL-AMS languages. Ian Dodd argued that it was important to mention compliance to a specific feature set. Michael Mirmak proposed that the BIRD specify compliance to a minimum version without specifically saying an updated version could not be supported. NEXT MEETING The DAC IBIS Summit will be held June 14, 2005. There will be no teleconference bridge. The next IBIS Open Forum teleconference will be held June 24, 2005 from 8:00 AM to 10:00 AM US Pacific Time. A vote is scheduled for BIRD94.1. ============================================================================ 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.
