CALL FOR PATENTS Stephen Peters called for any patents or pending patents related to the IBIS Version 4.0 Standard. No companies declared a patent. MEMBERSHIP UPDATE AND TREASURER'S REPORT Stephen Peters reported that, based on EIA confirmation of payment, the current paid membership stands at 20. In addition, the EIA is awaiting confirmation from one additional company and Stephen is expecting three more companies to join. This total is much better than the 16 paid members reported previously, but still down from the 30 members at the end of last year. Stephen reminded the group that if a company has not paid its dues by mid-June, we would begin the process of removing their name from the voting member list on the minutes. REVIEW OF MINUTES AND AR'S The May 9, 2003 minutes were approved without changes. ARs will be discussed during the meeting. MISCELLANY/ANNOUNCEMENTS Bob Ross reported that his presentation at the SPI 2003 IEEE Workshop on Signal Processing on Interconnects was a success. Bob enlightened his audience on the accuracy and usefulness of IBIS models. A copy of his presentation "IBIS Past and Future" is available at the following URL: http://www.spi.uni-hannover.de/ PRESS AND WEB PAGE UPDATES Stephen Peters reported that Syed Huq is making ongoing updates to the IBIS roster and upcoming events link. NEW MODELS AVAILABLE, LIBRARY UPDATE Bob Ross reported that Renesas Technology is offering some IBIS models that were formerly offered by Mitsubishi and Hitachi. These models are available at http://www.renesas.com/eng/ OPENS FOR NEW ISSUES Bob Ross asked to discuss spice2ibis3. INTERNATIONAL/EXTERNAL PROGRESS - IEC 62014-3 (ICEM) Integrated Circuit Electromagnetic Model Proposal (formerly, IEC 93/67/NP IBIS and EMC Simulation) - No report. - JEDEC Activity Report. Nothing to report. DAC2003 MEETING PLANNING Stephen Peters reported that planning continues for the June 5, 2003 IBIS summit meeting which will be held in conjunction with DAC2003 in Anaheim, California at the Anaheim Marriot hotel in Grand Ballroom Salons C & D. Cadence Design Systems is co-sponsoring the IBIS summit along with the IBIS Open Forum. Stephen noted that attendees should sign up with Guy de Burgh immediately if they have not already done so. Currently 15 persons have indicated that they will attend. John Angulo asked for a final head count to forward to the hotel and caterers. Finally, Stephen noted that this summit meeting will not be webcast. Stephen reminded the presenters that they should email their electronic presentations to Guy De Burgh by the end of the day Monday, June 2, 2003 so that hard copies can be made. If they are not available by that time, then the presenter is requested to bring 20 hard copies to the meeting. Lynne Green requested that presenters also email her a copy of their presentation, as she will be loading them on her laptop for use at the summit. Stephen Peters indicated that he will also bring his laptop as a backup. Guy will supply the LCD projector. Stephen noted that the following presentations are planned (titles are tentative). IBIS Chair's Report, Stephen Peters (Intel Corp.) IBIS Quality Committee Update, Kim Helliwell, (Apple Computer) ICM Status and Update, Michael Mirmak (Intel Corp.) IBIS 4.1 Status and Update, Lynne Green (Cadence Design Systems) Behavioral VHDL-AMS I/O buffer model using IBIS, Arpad Muranyi (Intel Corp.)

In addition to presentations and discussion we will also be conducting the annual election of officers. The current slate of nominees and their positions are: Chair Michael Mirmak, Intel Corp. Vice-Chair Lynne Green, Cadence Secretary Randy Wolff, Micron Librarian Roy Leventhal, Leventhal Design and Communications Webmaster Syed Huq, Cisco Postmaster John Angulo, Mentor Additional nominations are being accepted for all positions. E-mail nominee names to Stephen Peters. Nominations will also be accepted at the summit meeting. DESIGNCON2003 EAST MEETING PLANNING Stephen Peters reported that planning for an IBIS summit meeting at Designcon2003 East in Marlborough, Massachusetts continues. The summit is scheduled for June 23, 2003 in the Royal Plaza Hotel in Marlborough, Massachusetts. Sisoft and the IBIS Open Forum are co-sponsoring the event. The meeting room is yet to be determined. Stephen noted that we are also a co-sponsor of DesignCon2003 East. Barry Katz from SiSoft is serving as the contact for registration and sign-up, so if you are planning on attending please let Barry know. Stephen mentioned that we have traded the booth for a telephone line so that the meeting can be audio or web telecast. It is expected that presentations given at the DAC2003 Summit will also be given at this meeting. Bob Haller indicated that Sisoft may be able to supply the LCD projector. Stephen has the AR to find a sponsor for lunch. Stephen asked for a rough head count of who will attend. SiSoft will have a couple of representatives in attendance, and Tim Coyle indicated that he plans on attending in person. Most west coast individuals indicated that they will phone in for at least a part of the meeting. IBIS VERSION 4.0 PARSER FUNDING AND STATUS Stephen Peters reported that he has received word from EIA that a parser payment has been received from LSI logic. This brings the total companies that have paid to seven, with two more pending. Atul Agarwal has sent the alpha release of the IBIS 4.0 parser to Stephen, who has forwarded it on to John Angulo, Matthew Flora and Arpad Muranyi for testing. The alpha release incorporates all BIRDS approved for IBIS 4.0 with the exception of BIRD70 (Golden Waveforms). John noted that he has run a few test models, but has not yet gone through all the supplied test cases for bug fixes. Looking through the file, John noted that there appears to be test cases for BUGS 57, 58, 60, 61, and 63 through 67. John will verify the bug fixes then send a note to Michael Mirmak to close the bugs. Stephen stated that Atul asked if any numerical checks needed to performed on the Test Load waveforms analogous to those which are performed on the [Rising Waveform] and [Falling Waveform] tables. The consensus is that because these are composite waveforms and the end points could assume wide values, the end point checks are not required. IBIS VERSION 4.1 DISCUSSION Stephen Peters introduced the second discussion of IBIS version 4.1 by listing the BIRDS that have been approved since IBIS 4.0 was voted on. These BIRDS are as follows: BIRD 75.8 - Multi Lingual Modeling Support BIRD 77.2 - Differential subparameter additions BIRD 78.1 - comment line length limit BIRD 80.1 - Add External Reference Column to Pin Mapping Keyword BIRD 81.1 - Clarify Usage Rules for [Pin] I/O Model Assignment There are also several minor editorial corrections that will be included. Stephen asked the group if clarification language on summing clamp currents and allowing extension of the clamp table ranges was important enough to warrant a BIRD. Lynne Green stated that she feels this is important, and after discussion Lynne and Bob Haller agreed to author a BIRD for review at the next teleconference meeting. Stephen also asked if it was worth adding language to the [Driver Schedule] keyword that made it illegal to use [Driver Schedule] with a model type of 'Input'. After discussion it was decided to defer this change until we have had a chance to look at the [Driver Schedule] section as a whole. IBIS QUALITY COMMITTEE Bob Haller reported on the IBIS Quality Committee meetings held on May 20, 2003. They have completed review of the I-V document, and are now working on reviewing Mike Labonte's ramp and waveform processing document. Meetings are scheduled for June 10 and June 17, 2003 to wrap up the documentation reviews. IBIS MODEL REVIEW COMMITTEE Lynne Green reported that they have received and distributed models from Intersil and Intel. NEW ADMINISTRATIVE ISSUES Larry Barnes indicated that the T11 Fiber Channel committee is starting a modeling subgroup in which he is involved. Larry stated that he has been struggling with the T11 committee about the usefulness and accuracy of IBIS models, and Larry suggested that it would be helpful if he or someone from the IBIS Open Forum could present material at the next T11 meeting regarding IBIS. Several folks noted that Scott McMorrow and Tim Coyle (among others) have published presentations demonstrating IBIS accuracy at Ghz speeds. After further discussion Larry decided to pursue this further offline with Lynne Green. Finally, in response to a question from Bob Ross, Larry indicated that the T10 document Larry was working on previously is now an ANSI standard. IBIS FUTURES AND CONNECTOR WORKING GROUP REPORT Stephen Peters reported that, after a final review by email, the IBIS connector working group released the final draft of the Interconnect Modeling (ICM) specification to the IBIS Open Forum. A copy of the draft specification is available for review on the IBIS web site at http://www.eda.org/pub/ibis/connector/ The only remaining item is a minor update to the Touchstone specification. At this point the futures committee has no meetings planned. IBIS ICM SPECIFICATION REVIEW Michael Mirmak introduced the ICM specification for review. In brief, the ICM specification permits model authors to model a wide variety of interconnect, including connectors and packages. Topologies can be described via a tree or nodal connection, and connector swathing is supported. Coupling can be represented by RLGC matrices or S-parameter data formatted in Touchstone format. Michael indicated that an in depth look at the specification will be presented at the upcoming DAC summit, and in the mean time interested persons may reference the presentation given at the January 2003 IBIS summit. On a related topic Stephen Peters inquired about ICM parser progress. Lynne Green indicated that the parser is being developed as a two pass parser. Coding for the first pass is done and the second pass is in development. Lynne estimates that an alpha release could happen two to three weeks after the ICM specification is accepted. However, Kelly Green (the parser developer) will need models for testing. Bob Ross indicated that Teraspeed can provide a couple of test cases. Stephen will also ask Gus Panella to provide any test cases he has. Bob asked if the currently posted Word and .pdf documents can be modified to include a table of contents. Michael Mirmak will look into this. BIRD74.4 - EMI Parameters Guy de Burgh opened the discussion on BIRD74.4 by noting the changes from the previous version. Per Arpad Muranyi's suggestion the [Signal Swing] keyword has been removed. Connector related information has also been removed and will be re-introduced as part of the ICM specification. The syntax of keywords and subparameters has been updated to be consistent throughout the BIRD, and Guy asked for another person to review them to verify that they follow the standard IBIS rules. Finally, a subparemeter that indicates the heatsink condition (grounded or floating) has been added. Based on comments from Siemens and others Guy believes that all the outstanding technical issues have been addressed and that the BIRD is ready for a formal vote. Stephen indicated that he would schedule a vote on this BIRD at the June 27, 2003 teleconference meeting. IBISCHK3 & BUG TRACKING STATUS John Angulo reported no progress on prototyping the fix for BUG73, "Extreme Non-monotonic I-V Tables Cause End Point Test to Fail". John indicated that he will be rolling this in with the testing he is doing on the IBIS 4.0 parser. Stephen Peters stated that we need to eventually decide if we should do a final release of IBISCHK3.2 that includes the bug fixes now incorporated into IBIS 4.0. In the following discussion it was pointed out that the answer depends a lot on Atul Agarwal's availability. Stephen also noted that BUG68 thru BUG77 and BUG79 have yet to be implemented. Stephen will contact Atul and ask him if he plans to implement the fixes for these bugs. NEW ISSUES: Bob Ross Noted that he has received an email from North Carolina State University (NCSU) stating that they have a beta copy of a new SPICE to IBIS3 program. NCSU would like to limit the distribution of this beta version, but if you are interested in beta testing contact Lynne Green or Bob Ross. Bob will ask NCSU if they will consider sending a copy to Syed Huq, as he is the prime reflector resource for S2IBIS2 assistance. NEXT MEETINGS: The next IBIS meeting will be the IBIS Summit on June 5, 2003 at the Design Automation Conference (DAC) in Anaheim, California. No audio bridge or webcast is planned. The next teleconference meeting is scheduled for June 27, 2003 from 8:00 AM to 10:00 AM Pacific Daylight Time. A vote on BIRD 74.4 is planned. ============================================================================ NOTES IBIS CHAIR: Stephen Peters (503) 264-4108, Fax: (503) 264-1831 stephen.peters@intel.com Senior Hardware Engineer, Intel Corporation M/S JF4-215 2111 NE 25th Ave. Hillsboro, OR 97124-5961 VICE CHAIR: Lynne Green (425) 788-0412, Fax: (425) 788-4289 lgreen@cadence.com Senior Modeling Engineer, Cadence Design Systems 20 120th Ave NE, Suite 103, Bellevue, WA 98005-3016 SECRETARY: Randy Wolff (208) 363-1764, Fax: (208) 368-3475 rrwolff@micron.com Simulation Engineer, Micron Technology, Inc. 8000 S.
