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, at last report, the EIA has received a total of eight IBIS dues payments for the year out of 35 companies invoiced. However, Stephen noted that the last update was in mid January, so the total may have increased. Stephen is working with the EIA to obtain the latest ledger reports. Stephen also noted that he has not received a final 2002 financial report. REVIEW OF MINUTES AND AR'S The minutes of February 14, 2003 were approved without comment. ARs will be discussed during the meeting. MISCELLANY/ANNOUNCEMENTS None. PRESS AND WEB PAGE UPDATES Stephen Peters reported that Syed Huq is making ongoing IBIS roster updates. NEW MODELS AVAILABLE, LIBRARY UPDATE No new models reported. 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. Lynne Green commented that people can still sign up for the following IBIS Modeling class at the JEDEX conference on March 24, 2003 http://www.jedex.org/ Lynne is presenting two seminars. Seminar A is entitled "An Introduction to IBIS Models and Model Validation." Seminar B is called "IBIS Models for High-Speed Interfaces." The cost is $349 for members of JEDEC and $399 for non-members. DATE2003 EUROPEAN IBIS SUMMIT MEETING REPORT Bob Ross reported that he had received an e-mail from a participant stating that the IBIS summit meeting was a success. Stephen stated that he will add a report on the meeting to the March 28, 2003 teleconference agenda. In the mean time, minutes will be published and will be available on the IBIS web page at the following URL: http://www.eda.org/pub/ibis/summits/mar03/ DAC2003 AND DESIGNCON2003 EAST MEETING PROPOSALS Stephen Peters reported that planning for an IBIS summit meeting at Designcon2003 East in Boston continues. Stephen has signed the contract with the DesignCon officials, and a date of June 23, 2003 has been selected. Stephen noted that we will co-sponsor DesignCon2003 East. The next step will be to confirm a meeting room at the hotel. Stephen mentioned that we have traded refreshments for a telephone line so that the meeting can be web telecast. Planning also continues for an IBIS summit at the Design Automation Conference (DAC) on Thursday, June 5 2003 in Anahiem California. Stephen stated that this meeting costs about $2000, and if we do not meet our membership goals for this year we may be forced to cancel this summit. Stephen asked that any companies interested in co-sponsoring the event please contact him. Bob Ross and John Angulo will work together to reserve a room for IBIS at the Marriot Hotel in Anaheim. Bob Ross noted that presentations given at the DAC summit can be presented again at the DesignCon East summit in Boston. IBIS VERSION 4.0 PARSER FUNDING AND STATUS Stephen Peters reported that the EIA has received IBIS 4.0 parser payments from two companies, and verbal confirmation that one more company has paid. Five more companies have indicated that they are processing the paperwork. Stephen is working with EIA to get updated numbers. IBIS QUALITY COMMITTEE Lynne Green reported that the IBIS Quality Committee met on February 25, 2003 and will meet again on March 11, 2003. Lynne stated that the quality committee continues to review the quality documentation before release to the forum. Lynne noted that the review is going more slowly than expected. IBIS MODEL REVIEW COMMITTEE Lynne Green reported no new models to review. Lynne confirmed with Bob Ross that John Angulo will replace Bob on the model review committee. NEW ADMINISTRATIVE ISSUES None. IBIS FUTURES AND CONNECTOR WORKING GROUP REPORT Stephen Peters reported that the IBIS futures and connector working group met February 21, 2003 and again on February 28, 2003 to resolve the issues raised by Michael Mirmak and Kelly Green and captured at the January 2003 Summit Meeting. All the technical and editorial issues have been resolved, and Michael Mirmak is working to incorporate the changes into a revised draft specification. The futures and connector working group will review the final document at the next connector meeting before forwarding the revised specification to the IBIS Open Forum. Stephen also reported that Kelly Green, the ICM parser developer, is waiting for a final version of the ICM specification before releasing an alpha version of the parser. Kelly expects two weeks of testing before releasing a beta version. Stephen also reported that Lynne Green has offered to act as a 'gatekeeper' for the ICM parser. A gatekeeper is required as the ICM parser code will be open source. During the discussion on gatekeeper responsibilities, Guy de Burgh offered to assist Lynne in code compilation on Solaris and HP platforms. Bob Ross and Michael Mirmak asked if a separate bug reporting structure would be set up to report ICM parser bugs. After a short discussion, the consensus was reached to set up an ICM bug reporting list separate from the existing IBIS parser bug list. BIRD74.2 - EMI Parameters BIRD79 - Non-linear buffer impedance (extension to C_comp) Stephen Peters opened discussion by noting that action has been deferred on these BIRDS. Previous discussions have indicated that the modeling issues addressed by these BIRDS are best covered by the multi-lingual modeling extensions. Stephen proposed an up or down vote on BIRD74.2 and BIRD79 at the next teleconference. Arpad Muranyi asked what options exist for capturing the information contained in BIRD 79 if it is rejected. Stephen recommends that a white paper be written that captures the method for modeling complex output impedance. Arpad agrees and remarked that future technical enhancements to the IBIS specification will focus more on documenting modeling techniques (equations, etc.) rather than BIRDS. Bob Ross suggested expanding the IBIS cookbook to include this information. Arpad pointed out that some of the modeling techniques may go into more detail and depth than usually placed in the cookbook. Finally, Bob pointed out that BIRD74 is really an extension of IBIS into a new area rather than a technical enhancement, and the strategy for documenting BIRD74.2 might be different. Bob also suggested that the BIRD authors should suggest alternate ways of documenting the ideas encompassed by BIRD74 if it is indeed rejected. Stephen will schedule a vote on BIRDS74.2 and BIRD79 at the March 28, 2003 teleconference meeting. IBISCHK3 & BUG TRACKING STATUS Stephen Peters noted that there are 12 open bugs against the current parser. Of these 12 bugs, two of them (BUG75 and BUG76) have a code fix supplied. In addition, BUG68 requires only a straightforward message change from 'error' to 'warning'. Stephen will ask Atual Argarwal if he can incorporate these three bug fixes into the IBIS 4.0 code as part of the IBIS 4.0 code delivery. As for the remaining BUGS, three BUGS (BUG71, BUG74 and BUG78) are still being discussed and no final resolution has been reached. This leaves five bugs that require investigation into a proposed fix. These bug are as follows: - BUG68, False messages with repeated voltages. John Angulo agreed to look into a proposed fix for this bug. - BUG70, [Model Selector] fails for [Series Pin Mapping] Models. Michael Mirmak agreed to look into a proposed fix for this bug - BUG72, Tab warning message promotion. No person assigned. - BUG73, Extreme Non-monotonic I-V tables cause end point test to fail. As this bug may be related to BUG68, John Angulo agreed to look into this bug also. - BUG77, Test for Series* Models in [Pin] error - Michael Mirmak agreed to investigate this bug and propose a fix. It was noted that BUG70 and BUG77 are specification violation bugs, and so are the ones we most want to fix in the IBIS 3.2 parser and propagate into the IBIS4.0 parser. - BUG71 - Monotonic Checking for Combined I-V Tables Bob Ross has been discussing the clarification of I-V table combinations with Bob Haller. Stephen will post Bob Haller's response to the reflector for discussion and resolution at the next teleconference. The current thinking is that changing the non-monotonic checks to check the summed curves is the proper thing to do. In response to a question, Stephen Peters mentioned that these proposed checks would replace the existing non-monotonic checks. - BUG74 - Missing Timing Test Load Warning Messages Greg Edlund has updated this bug with clarification of assumed default values for Cref, Vref, etc. Further action is postponed until the rest of the Open Forum has had a chance to review the contents of the bug report. Stephen will post the clarification to the IBIS reflector for discussion and disposition at the next teleconference. - BUG78 - Clamp Current Double Counting Test Bob Ross mentioned that BUG78 has not yet been classified because it contains a general problem, but no recommended proposal. Bob does not expect any further work on it. Bob suggests we classify it as Enhancement, LOW, and WILL NOT FIX. A new BUG report could be filed if the problem needs to be raised again. NEW TOPIC: Arpad Muranyi asked about the timeline for consideration of IBIS 4.1 and when it might be ready for ballot. Stephen replied that barring unexpected issues with the incorporation of BIRD75 (multi-lingual modeling), he expects that a vote to ratify IBIS 4.1 will occur in late May. NEXT MEETING: The next teleconference meeting is scheduled for March 28, 2003 from 8:00 AM to 10:00 AM Pacific time. A vote on BIRD74.2 and BIRD79 is scheduled. ============================================================================ 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.
