MEMBERSHIP UPDATE AND TREASURER'S REPORT Stephen Peters reported that he has received from EIA an updated balance sheet through March as well as an updated ledger report. According to the latest report, paid membership remains at 16 members, which is down signifi- cantly from last year at this time. GEIA has sent out a reminder letter to those who have not paid their dues yet, and Stephen will begin the process of following up with members individually. Stephen stated 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 April 18, 2003 minutes were approved without changes. ARs will be discussed during the meeting. MISCELLANY/ANNOUNCEMENTS None. PRESS AND WEB PAGE UPDATES Stephen Peters announced that Bob Ross will be at the the Signal Propagation on Interconnects (SPI2003) workshop as a keynote speaker on "IBIS Present and Future" on Wednesday, May 14, 2003. Stephen Peters reported that Syed Huq is making ongoing updates to the IBIS roster and upcoming events links. NEW MODELS AVAILABLE, LIBRARY UPDATE None. OPENS FOR NEW ISSUES None. 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.

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. Lynne Green has posted the second announcement to the reflector. Stephen also noted that attendees should sign up with Guy de Burgh and start making their travel arrangements. Finally, Stephen announced that he will be attending the summit. John Angulo reported on the final cost proposal for the meeting. Assuming 20 attendees, the cost for the meeting space and lunch will be approximately $1,600. The meal will be a chicken and pasta dish, and Stephen noted that if an attendee wishes a vegetarian meal, they should note this when they register for the summit. John stated that he needs a final head count for meals three days prior to the meeting. John also inquired how the billing will be handled. Stephen will follow-up with Chris Denham at GEIA and see if GEIA can be billed directly. Guy de Burgh indicated that he will supply an LCD projector. Stephen noted that after consultation with Arpad Muranyi, and considering the additional cost and the fact that Stephen can attend in person, the decision was made to not telecast the meeting. Stephen noted that the following presentations are planned (titles are tentative). IBIS Status Update, Stephen Peters (Intel Corp) Behavioral VHDL-AMS I/O buffer model using IBIS, Arpad Muranyi (Intel Corp) Quality Committee Update, Barry Katz (SiSoft) Observations on Problems Encountered, Atsuji Ito (Panasonic) ICM Status and Update, Michael Mirmak (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 continues. The summit is scheduled for June 23, 2003 in the Royal Plaza Hotel in Marlborough, Massachusetts, and Sisoft is a co-sponsor, along with IBIS. 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 refreshments for a telephone line so that the meeting can be web telecast. It is expected that presentations given at the DAC2003 Summit will also be given at this meeting. It was noted that we will need to obtain an LCD projector for the room at DAC. Stephen will inquire with potential attendees. Finally, Stephen noted that the first meeting announcement has been posted to the reflector and that a second announcement should follow in the coming weeks. IBIS VERSION 4.0 PARSER FUNDING AND STATUS Stephen Peters is still awaiting confirmation from GEIA that they have received the payment from Huawei. This brings the total companies that have paid to six, with three more pending. Stephen also reported that Atul Agarwal is ready to send an alpha release of the parser to John Angulo and Matthew Flora for initial testing. This alpha release will include all the IBIS 4.0 BIRDs with the exception of BIRD70, Golden Waveforms ([Test Load] and [Test Data] keywords). Arpad Muranyi would also like a copy of the source code for testing. IBIS VERSION 4.1 DISCUSSION Stephen Peters introduced the first 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 noted that he expects a draft copy of IBIS 4.1 to be available on the IBIS web page within the next week or so. Stephen asked those in attendance to review the document when it is released. The plan is to have the first formal reading of the specification at the May 30, 2003 meeting. IBIS QUALITY COMMITTEE Bob Haller reported on the IBIS Quality Committee meetings held on April 22, 2003 and May 6, 2003. Attendance remains stable. The committee is continuing to work its way through the model section of the quality document, focusing on I-V table issues and checks. The next meeting is scheduled for May 20. IBIS MODEL REVIEW COMMITTEE Lynne Green reported that they have received and distributed models from both Fairchild and Phillips. NEW ADMINISTRATIVE ISSUES None. IBIS FUTURES AND CONNECTOR WORKING GROUP REPORT Stephen Peters reported that the IBIS connector working group met on April 24, 2003 and again on May 8, 2003. All outstanding editorial issues have been dealt with, but much e-mail has been exchanged on a larger technical issue of ICM and Touchstone file support for mixed-mode s-parameters. The connector working group resolved the issue by removing language that prohibited mixed-mode s-parameter representations from appearing in the Touchstone data file, with the caveat that Touchstone files currently have no defined mixed-mode s-parameter data format. A final draft version of the ICM specification has been released, and after a final review by the connector working group, it is expected to be posted on the IBIS web site by Friday, May 16, 2003 for review by the IBIS Open Forum. BIRD74.3 - EMI Parameters Guy de Burgh opened the discussion on BIRD74.3 by noting the changes from the previous version. The [Family] keyword was removed, the keyword [Voltage Range] was changed to [Signal Swing], a subparameter for clock division was added, and several syntax issues were addressed. Guy then queried the group on how they expect to extract signal swing from the existing V-T tables. Guy will take this discussion offline with Arpad Muranyi. Stephen asked how signal swing was defined if the buffer included pre-emphasis. Guy replied that at the current level of accuracy the exact pre-emphasis or de-emphasis voltage swing does not make much of a difference. In response to a comment from the last teleconference, Guy explained how to handle cases in which a component heat sink was optional. The [Heatsink Capacitance] keyword is optional, therefore if the keyword is present the heatsink is assumed attached, else if the keyword is not present, then the heatsink is assumed not present. Stephen Peters noted several IBIS syntax issues dealing with keywords and subparameters. Stephen will provide corrections to Guy offline. Finally, Guy noted that he has been persuaded to remove from this BIRD keywords that deal specifically with connectors, with the expectation that they would then be proposed for inclusion in a later revision of the ICM specification. Stephen replied that he was agreement with this. Guy will issue BIRD74.4 with the noted changes for discussion at the next teleconference. NEW TECHNICAL DISCUSSIONS Stephen Peters asked for comments on the recent mail reflector discussion regarding extracting clamp information for receivers with on-die termination. It was noted that one part of the solution to properly modeling on-die termination in receivers is to provide data over the full -POWER to 2*POWER range, rather than the more restrictive range called out by the IBIS specification. Arpad Muranyi noted that he teaches his students to extract clamp data over the extended range. Bob Haller remarked that there is confusion between the IBIS cookbook and the specification in regards to clamp summing. The proper method is to sum both the [GND clamp] and [POWER Clamp] tables to the individual [Pullup] and [Pulldown] tables, but neither the specification or cookbook explicitly says this. Arpad suggests reading the IBIS specification again and propose clarifying language if necessary to make sure the additive nature of the clamp tables is specified. It was also noted that text is needed that states that the current GND and POWER ranges are a minimum, and that larger ranges are acceptable and may be needed for properly modeling receivers with on-die termination. Finally, Arpad offered to do a presentation on modeling receivers with on-die termination at the upcoming DAC summit meeting. Stephen would also like to see a BIRD that would add the clarifying language cited above. IBISCHK3 & BUG TRACKING STATUS John Angulo reported that there has been no progress on prototyping the fix for BUG73, "Extreme Non-monotonic I-V Tables Cause End Point Test to Fail". John will pursue this further when he receives the prototype IBIS 4.0 parser from Atul Agarwal. - BUG71 - Monotonic Checking for Combined I-V Tables Bob Haller reported that the corrected I-V table has been posted to the BUG data base. He then asked if the proposed "summed curve" monotonic checks should replace the current individual checks. Stephen Peters replied that he would like to see the proposed checks replace the current checks. The questions was asked about what kind of interpolation between tables - linear or spline - should be used. After discussion the consensus was to use linear. With this settled BUG71 was assigned a status of 'Will Be Fixed'.
