Michael Brenneman is an applications manager for Ansoft, while Mary Tolikas is associated with their business operations. Mary works in their Burlington, MA office, and Michael is located in San Jose, CA. 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 are closing out the year with 23 members. Ansoft joined in the last couple of weeks and will be a member next year as well. A proposed budget for 2005 has been submitted to GEIA. There are already 18-19 members committed for 2005, so we are on track for a significant increase in membership for next year. Membership invoices will go out the first two weeks in January. REVIEW OF MINUTES AND ARS Michael Mirmak reviewed the minutes of the October 29, 2004 IBIS Open Forum teleconference. The minutes of the meeting were approved without change. MISCELLANY/ANNOUNCEMENTS None. PRESS AND WEB PAGE UPDATES Syed Huq reported that he has updated the poster page. He will add Ansoft and Freescale now that they are confirmed members. Other updates are being made to the roster listings as well. NEW MODELS AVAILABLE, LIBRARY UPDATE Michael Mirmak reported for Lance Wang that a Micrel Semiconductor models link was added to the Models page. OPENS FOR NEW ISSUES No update. MAILING LIST ADMINISTRATION Bob Ross reported that nothing new has happened. He also mentioned that about 400 people in total worldwide are on the list. INTERNATIONAL/EXTERNAL PROGRESS Michael Mirmak reported he attended the IEEE Design Automation Standards Committee (DASC) meeting held at Mentor Graphics in San Jose on Friday, November 12. DASC helps to foster design standards such as VHDL, VHDL-AMS, Advanced Library Format (ALF), etc. Michael gave a presentation about keeping IBIS and ICM tied in with DASC for purposes of our integration of AMS into IBIS. DASC members were interested in IBIS overall, but the consensus was that IBIS should approach individual working groups of interest under the DASC umbrella, specifically the VHDL-AMS group. Michael is making contact with the appropriate groups. Michael was approached by the chair of the ALF group. There is interest in IBIS being incorporated as part of the ALF specification. SUMMITS - DesignCon IBIS Summit, January 31, 2005, Santa Clara, CA DesignCon 2005 will take place January 31 - February 3, with a Summit scheduled for Monday, January 31. Michael Fister, the CEO of Cadence, will be the keynote speaker during the free lunch. The first call for papers will be sent out shortly. Bob Ross mentioned that we need to arrange for refreshments during the meeting. Michael Mirmak will try to get the IEC to provide them. - DATE European IBIS Summit, March 11, 2005, Munich, Germany DATE 2005 will take place in Munich, with a Summit planned for Friday, March 11. Ralf Bruening of Zuken is making arrangements for the room and other logistics. Bob Ross reported that Ralf is waiting for confirmation of the room request. - JEITA Asian IBIS Summit, Feb-March 2005, Tokyo, Japan JEITA members are still in the planning stages. Michael Mirmak reported that messages from JEITA representatives have been received recently. It is looking like a March summit is very probable. JEITA is interested in technical information regarding IBIS4.1 and ICM. There should be 30 participants including three from the US. Suggestions have pointed towards Thursday, March 17 or 24 for the summit. Sponsorship opportunities for all these Summits are still available, with sponsors receiving free mentions in the minutes, agenda, and other announcements. IBIS ANSI BALLOT STATUS Randy Wolff reported that ballots for IBIS 3.2 reapproval were sent out on Thursday morning. Members have until December 23 to return their ballots via email. It was noted that Otto Bennig of Samtec did not receive an email. Frank Gasparik also reported having problems with his email bouncing back. Bob Ross questioned who the ballots were being sent to. Randy took the AR to check into the balloting issues. S2IBIS3 STATUS No updates. Bob Ross mentioned that Ambrish Varma's website received over 1000 hits recently related to S2IBIS3. S2IBIS3 beta executables can be downloaded from: http://www.ece.ncsu.edu/erl/ibis/s2ibis3/s2ibis3.htm Feedback on the current version is appreciated and encouraged. IBIS VERSION 4.1 PARSER STATUS Bob Ross reported that the parser has passed the beta version, but there are three or so technical issues open to be resolved. Once these issues are closed, the parser will be released as version 4.1.0. The expected release is January/February 2005. ICM SPECIFICATION AND PARSER STATUS Michael Mirmak gave an update for Lynne Green. The IIRDs discussed today will have an effect on the parser, so changes will need to be made to the parser eventually. IBIS QUALITY COMMITTEE Bob Haller reported that the committee is meeting the first Tuesday of each month with the next meeting December 7. Future plans the committee is discussing include automation of the checklist, BIRDS for checks that should be in the parser but are not, and pushing to get people to use the standard checklist and provide feedback. Bob plans to put together a kit with the checklist and an example model and send out a link to the users group. Putting a link on the main eigroup IBIS website was also discussed. IBIS MODEL REVIEW COMMITTEE No update. FUTURES AND COOKBOOK COMMITTEES Michael Mirmak reported that both committees met November 18 for one hour each. The Cookbook committee went over the latest changes to the draft cookbook. There was much discussion on the differential section including the need for more information on validation and data extraction. There was a proposal to put packaging and ICM information in a separate cookbook. The Futures committee discussed links between IBIS and ICM including how pads and pins are hooked together. Recent committee material is stored at: http://www.ibis-information.org/futures/ NEW ADMINISTRATIVE ISSUES None. BIRD91.2: MULTI-LINGUAL LOGIC STATES CLARIFICATION Ian Dodd summarized that the BIRD is needed to ensure tools and models are in agreement. Bob Ross expressed his concerns of embedding specific version numbers of software in the specification. Ian responded that the software mentioned will be backwards compatible, so it should not be a problem. Bob also noted the need for a minor editorial change of some parentheses. A vote was called for with the noted minor editorial changes for inclusion in IBIS 4.2. The BIRD was approved unanimously by the members present. BIRD92: MULTIPLE TERMINATOR AND SERIES ELEMENTS UNDER [MODEL] Michael Mirmak introduced the BIRD. It addresses the fact that terminator keywords are single ended. The specification does not specifically prevent one from putting [Rac] and [Cac] more than once under the same [Model] keyword. The parser issues an error when more than one instance of these keywords is under [Model]. The same is true of the [* Series] keywords under the [On] or [Off] keyword. Both of these things should be errors, so the specification needs to be clear. Nothing will need to changed in the parser. Bob Ross mentioned making an editorial change to the BIRD description. Michael will issue a revised version shortly. BIRD93: MODEL AND SIGNAL NAME LIMIT EXTENSION Michael Mirmak reported that this BIRD was filed at the request of a couple of organizations whose internal processes for generating models created longer internal model names than allowed by the specification (20 characters). This BIRD changes that limit to 40 characters for the [Model] keyword. This is possible due to BIRD78.1 allowing the 120 character maximum line length. The model name is extended in [Series Pin Mapping] and in [Model Selector] as well. Bob Ross noted that the BIRD needs a justification statement stating why 40 characters has been chosen as the limit. IIRD2.3: FREQUENCY DEPENDENT RLGC MATRICES Michael Mirmak summarized the IIRD. It adds a [Frequency] keyword to allow matrices to show frequency dependencies. The IIRD updates the description of [Resistance Matrix] to no longer refer to DC resistance. It also states that if data is not included for specific frequencies, it is assumed to be zero. The IIRD now includes changes made from IIRD7.1 for consistency. Michael has a cleaned up version to make it easier to read through that he can make available on request. The IIRD will be put up for a vote at the next meeting. IIRD8: DISTINCT MODEL_PINMAP AND MODEL_NODEMAP NAMES Bob summarized IIRD8 and also introduced IIRD8.1, althought IIRD8.1 had not been officially released. ICM currently contains the Model_nodemap and Model_pinmap subparameters, which point to the ICM keywords defining the pinlists of the interconnect and how they map to the nodal or tree path conductors. Right now, there's no rule which says you have to have different pinmaps or nodemaps for each endpoint. IIRD8 will force each set of endpoints to have a unique pinmap or nodemap. This way, the tool always knows which end of the interconnect is being stimulated, connected, etc. IIRD8.1 permits you to use a single pin/nodemap name if you wish, but creates a new subparameter called "Side" which will help the tool identify which end of the interconnect is being used. This is similar to the subcircuit (SUBCKT) definition used in SPICE. The IIRD will be put up for a vote at the next meeting. IBISCHK4 BUG STATUS Michael Mirmak reported that no new BUGS have been filed. Recent BUGS have been processed, but it needs to be determined how to deal with fixing them. NEW TECHNICAL ISSUES Michael Mirmak mentioned that in transitioning from IBIS 4.1 to IBIS 4.2, we must make sure that the intent of IBIS 4.1 is realizable. There needs to be a clean way for those building models to understand how a particular pin ties to a particular pad. IIRD8 will help provide a methodology for this with ICM. NEXT MEETING An Open Forum teleconference has been scheduled for December 10, 2004 from 8:00 AM to 10:00 AM US Pacific Time. Votes are scheduled for BIRD92, BIRD93, IIRD2.3, and IIRD8.1. ============================================================================ 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.
