No companies declared a patent. MEMBERSHIP UPDATE AND TREASURER'S REPORT Stephen Peters reported that he has received a financial and ledger statement for February 2003, but nothing more current. So far as Stephen is aware, the total paid membership remains at 16 members. Stephen continues to work with GEIA to obtain a current financial and dues payment report. REVIEW OF MINUTES AND AR'S Stephen Peters noted two minor corrections to the March 28, 2003 minutes. The JEDEX class taught by Lynne Green was held in San Jose, not San Diego. Also, under the discussion of BUG73 (IBISCHK3 status agenda item) John Angulo requested that the following sentence be revised from: "In brief, non-monotonic points in the clamp table cause the parser to extrapolate the table endpoints incorrectly, thus the end point test fails." to: "In brief, the parser extrapolates non-monotonic end-points in the clamp table correctly, but the V-T end point test fails because of the non-monotonicity." The March 28, 2003 minutes were approved with the above changes and Michael Mirmack will upload the corrected minutes. ARs will be discussed during the meeting. MISCELLANY/ANNOUNCEMENTS None. PRESS AND WEB PAGE UPDATES Bob Ross indicated that he will attend 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 link. 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. 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. Lynne Green has posted the first announcement to the reflector. Stephen also noted that attendees should sign up with Guy de Burgh and start making their travel arrangements. Cost for the meeting is estimated to be between $2,300 and $2,500 depending on the number of attendees and the lunch selected. A vegetarian option would be about $30 a plate, a meat entree would be about $35 a plate. To reduce cost Stephen suggested eliminating the afternoon refreshments, which will save approximately $15 a person. After discussion the group agreed to forgo the afternoon refreshments and go with the vegetarian option for lunch. John Angulo will follow up with the hotel. Stephen again mentioned that we are looking for co-sponsors to fund part of or all of the lunch. Guy de Burgh indicated that he will supply an LCD projector. In response to a question from John Angulo, we agreed to drop the overhead projector and go with a flip chart package instead. Stephen asked Arpad Muranyi to inquire if a local Intel office can be used as the dial-in point for a teleconference bridge. Stephen noted that the following presentations are planned (titles are tentative). IBIS Status Update, Stephen Peters (Intel Corp) VHDL AMS Modeling, Arpad Muranyi (Intel Corp) Quality Committee Update, Barry Katz (SiSoft) Lynne Green indicated that either herself or Michael Mirmak will be presenting an ICM specification update. 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 continues. The summit is scheduled for June 23, 2003 in the Royal Plaza Hotel in Marlborough, Massachusetts. The meeting room has 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 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 week. IBIS VERSION 4.0 PARSER FUNDING AND STATUS Stephen Peters reported that he received an e-mail from Huawei confirming that they have sent in payment for the parser. Stephen is still awaiting confirmation from GEIA that they have received the payment. This brings the total companies that have paid to six, with three more pending. Stephen has not heard back from Atul Agarwal on parser progress. It was noted that when we do receive the prototype code John Angulo and Matthew Flora will be in charge of testing. IBIS QUALITY COMMITTEE Bob Haller reported on the IBIS Quality Committee meeting held on April 8, 2003. The quality committee is about half way through its document review and is currently working on the model section. The next meeting is scheduled for April 22, 2003. IBIS MODEL REVIEW COMMITTEE Lynne Green reported that they have received and distributed a model from Phillips. NEW ADMINISTRATIVE ISSUES None. IBIS FUTURES AND CONNECTOR WORKING GROUP REPORT Stephen Peters reported that the IBIS connector working group met on April 4, 2003 and again on April 10, 2003. The editorial comments on the Touchstone specification have been addressed, although the document itself has yet to be updated. On the ICM specification itself a 'Draft E' has been issued, however there remain two open issues. One issue involves the exact definition of "text block". The other issue involves the proper way to designate AC return paths in the matrices. After discussion the connector working group members agreed to hold a meeting on April 24, 2003 to resolve these final issues, with the expectation that they would then release the final draft 1.0 ICM specification to the IBIS Open Forum. BIRD74.2 - EMI Parameters Stephen Peters opened the discussion by noting that Guy de Burgh posted to the IBIS reflector a recap of BIRD74.2 for discussion. Guy stated that it has been almost a year since we have had technical discussions on this BIRD. After a short overview of the BIRD's history a technical discussion ensued. Stephen asked what was the intent of the "Family" keyword. Guy replied that this keyword was intended to cover cases in which critical information about a part was not available, but could be estimated if one knew the logic family type. After discussion Guy agreed that if information is critical it should be present, and he is in favor of removing this keyword. Guy also clarified that the frequency parameter was meant to specify the operating frequency of the I/O pins as a ratio of the highest internal frequency. There were several questions on the 'heatsink capacitance' parameter. Stephen asked how to derive this parameter. Guy stated that the intent is to estimate heatsink capacitance assuming a traditional parallel plate configuration between the heatsink and PCB power/gnd plane. Bob Ross and others asked how this parameter would be used in cases where a heatsink is optional. The consensus was that two IBIS models would be required, depending on if the heatsink is present or not. However, there may be other issues that need to be explored. Finally, Stephen suggested renaming the proposed voltage range parameter to "signal swing". Several folks pointed out that signal swing could be derived from the existing I-V tables, and that may be even more applicable. (However, it was later noted that in IBIS 4.1, I-V tables might not always be available). Stephen asked what would be entered for voltage swing for a serial bus that employs equalization techniques such as de-emphasis. Guy replied that the intent was to capture the average signal swing. No conclusion was reached on what was meant by average. Guy will issue BIRD74.3 with changes for more discussion at the next teleconference. IBISCHK3 & BUG TRACKING STATUS John Angulo reported that he has looked into a proposed fix for BUG73, "Extreme Non-monotonic I-V Tables Cause End Point Test to Fail". In brief, John proposed that the parser should ignore any intersection points that lie beyond the ground or power rail values. John noted that BUG73 was actually introduced by the fix for BUG57, and the proposed fix for BUG73 was actually a better fix for BUG57. John will prototype this bug fix and, if it works, forward it to Atul Agarwal for incorporation into the IBIS 4.0 parser. - BUG71 - Monotonic Checking for Combined I-V Tables Bob Haller posted to the reflector an updated table for BUG 71 that added entries for ECL models and terminators. Stephen noted that by combining curves, interpolation of voltage points may be required, and he wondered if this might introduce unintended non-monotonic errors. No one was sure if the current parser has a limit that prevents very small voltage differences from causing non-monotonic errors. It was also noted by several individuals that the first row of the posted table ('Input' model type) has a TAB error that causes the 'XXX' values to show up in the wrong column. Michael Mirmak will fix this error before uploading the table to the BUG report. After discussion we decided we needed more time to verify the table. We will assign a final resolution at the next meeting. - BUG74 - Missing Timing Test Load Warning Messages Stephen Peters posted the clarification text to the IBIS reflector. After discussion we agreed to accept the revised table and classify the BUG as 'to be fixed'. Michael Mirmak will upload the updated bug report.
