CALL FOR PATENTS Michael Mirmak called for any patents or pending patents related to the IBIS 3.2, IBIS 4.2, IBIS 5.0, Touchstone 2.0 or ICM 1.1 specifications. No patents were declared. REVIEW OF MINUTES AND ARS Mike LaBonte called for comments regarding the minutes of the March 9, 2012 IBIS Open Forum teleconference. The minutes were approved without changes. MEMBERSHIP STATUS AND TREASURER'S REPORT Bob Ross reported that there is no official report. An inquiry has been sent to TechAmerica asking for an update. We have one new TSCHK2 parser source code sale to Cadence. There are also separate funds held in China accounts. WEB PAGE UPDATES Mike LaBonte reported that the roster page has been updated simply replacing 2011 with 2012. Also, TechAmerica has been asked to fix one of their web pages, currently linking to our now defunct eigroup.org URL. The page in question is the first result returned from a search for “IBIS” on techamerica.org. It contains a note from June 2011 that “We are still transferring data from our old site”. Bob Ross suggested eliminating that message, since no further migration is planned. Michael Mirmak noted that TechAmerica is attempting to create new web facilities using technologies such as Kavi and LinkedIn. Mike said we would not be able to easily migrate our existing content to those, so no further migration is planned. MAILING LIST ADMINISTRATION Mike LaBonte reported that there seems to be no technical resolution for the effective ban since December 2011 on attachments sent to any of the ibis@eda.org lists. Very few people tend to send attachments, with the exception of IBIS officers. An experiment to see if meeting and document notices generated by the TechAmerica Kavi system could be passed through automatically to the IBIS list failed because the emails contain attachments. Mike suggests informing people that attachments will not work and offering an alternative. The support web page could be updated for this. Michael Mirmak liked the idea. Walter Katz asked if a Gmail account could forward the emails, or if an email alias could do it. Mike said we really need the services of something like Majordomo to be able to manage the subscription list without administrator privileges. Bob Ross said that Freelists could be used, but that generates quite a bit of “garbage” email for administrators. Mike described some of the issues with Freelists, which we use for the task groups. The si-list also uses Freelists, and attachments are disallowed by Freelists policy. MODEL LIBRARY UPDATE Anders Ekholm reported that the models page has been updated. Thirteen broken links need to be investigated. MISCELLANY/ANNOUNCEMENTS None. OPENS FOR NEW ISSUES Bob Ross asked that we reserve time today to discuss parser issues including Touchstone. Walter Katz noted that other large groups have a practice of asking members to reply to an email sent 5 minutes ahead of meetings if they will participate, to help identify the meeting participant list more accurately. INTERNATIONAL/EXTERNAL ACTIVITIES - IEEE DASC Michael Mirmak reported that there has been no activity. - VHDL-AMS Table-Driven Models Arpad reported that the next meeting will be April 9. More information can be found at: http://www.eda.org/twiki/bin/view.cgi/P10761/ProjectsArea#Table_driven_ Modeling_Champion_J - Conferences SPI2012 (18th IEEE Workshop on Signal and Power Integrity) will be held May 13-16, 2012 in Sorrento, Italy. We are offered a free room on Wednesday afternoon for hosting an IBIS Summit meeting. There may be some technical papers related to IBIS. More information can be found at: http://www.spi2012.org - EPEPS (21st IEEE Conference on Electrical Performance of Electronic Packaging and Systems) will be held October 21-24, 2012 in Tempe, Arizona. This event occasionally includes IBIS-related content. More information can be found at: http://epeps.ece.illinois.edu/ Official IBIS participation may/may not be planned for all of the events above, though individual papers and discussion on IBIS are encouraged. These are events with refereed submissions, with deadlines either pending or already passed. - Press Update None. IEC APPROVAL ACTIVITIES No update. Michael Mirmak said we are waiting for meetings to be announced. SUMMIT STATUS - European Summit Planning The meeting will take place May 16, 2012 after the SPI conference in Sorrento, Italy. A room has been donated by the SPI conference for Wednesday afternoon. Lance Wang will be handling sign-ups. Lance said the 2nd call for participation will go out today. Bob Ross said the room has been donated free of charge. Anyone interested should sign up soon for discount rates. There will be several IBIS related papers at SPI. We have at least 2 possible papers so far for the summit. Michael Mirmak thanked the sponsors so far, including Micron Technology, Nokia Siemens Networks and Zuken. Bob said the summit would most likely be in the same room SPI uses, after they end. Lance said he would be there, and maybe Randy Wolff, Anders Ekholm, and Eckhard Lenski too. - DAC Summit Planning Michael Mirmak reported that the summit meeting will be held all day Tuesday, June 5, 2012 in San Francisco, CA. Details of the meeting room location are to be determined. We should know within a week or so. Mentor Graphics is arranging for the room, which probably will be in a hotel near Marconi Hall. Sponsorship opportunities for all upcoming IBIS summits are available, with sponsors receiving free mentions in the minutes, agenda, and other announcements. This includes upcoming events in Asia. Contact the IBIS Board for further details. QUALITY TASK GROUP Mike LaBonte reported that the group continues to examine parsers for their role in improving IBIS quality. They have been testing tschk2 relative to a somewhat obscure crash bug on Linux. The fix involves simply recompiling the executables with different switches. No formal bug report or executable update is yet posted. The effort to generate new bug reports for IBISCHK has been put on the back burner to wait for planned enhancements related to AMI BIRDs to be incorporated first. There continues to be interest in the idea of an AMI quality checklist, but with their policy of avoiding overlap with IBISCHK this effort is also in wait mode. Meanwhile they decided to move to a 4 week meeting interval to accommodate the slower work pace. The next meeting will be held April 17. The Quality Task Group checklist and other documentation can be found at: http://www.eda.org/ibis/quality_wip/ MODEL REVIEW TASK GROUP No update. ADVANCED TECHNOLOGY MODELING TASK GROUP Arpad Muranyi reported that they are meeting every Tuesday, discussing the various existing AMI model proposal and BIRDs. Task group material can be found at: http://www.eda.org/ibis/macromodel_wip/ EDITORIAL TASK GROUP Michael Mirmak reported that the group continues to meet weekly. They have addressed scrubbing suggestions from Bob Ross. The IBIS reformatting documentation can be reviewed at: http://www.eda.org/ibis/editorial_wip/ NEW ADMINISTRATIVE ISSUES None. BIRD116: ADD IBIS-ISS TO [EXTERNAL MODEL] AND [EXTERNAL CIRCUIT] AS A SUPPORTED LANGUAGE Discussion was tabled. BIRD117.3: PARAMETERIZE A_TO_D AND D_TO_A CONVERTERS Discussion was tabled. BIRD118.2: ANALOG PARAMETER ASSIGNMENTS Discussion was tabled. BIRD121.1: IBIS-AMI NEW RESERVED PARAMETERS FOR DATA MANAGEMENT Discussion was tabled. BIRD122: IBIS-AMI NEW RESERVED PARAMETERS FOR ANALOG MODELING Discussion was tabled. BIRD123.2: IBIS-AMI NEW RESERVED PARAMETERS FOR JITTER/NOISE Walter Katz suggested that we could discuss this rewrite against IBIS 5.1, or vote on it now to have that work considered by the editorial group. Walter moved to untable BIRD 123.2. Bob Ross seconded. There was no objection. Walter believed the ATM group had agreed to forward the BIRD for a vote. Radek Biernacki said the only questions were about correctness with regard to IBIS 5.1. Michael Mirmak said this was last discussed January 27. Bob suggested discussing it in a few editorial meetings before voting. Jitter might go into a separate chapter in the IBIS specification. Michael noted that from a technical perspective the BIRD meets general approval. He asked if editorial work could produce any technical changes, and if the lack of a vote was currently delaying industry implementation. Arpad Muranyi said that once a BIRD is voted, software companies could theoretically start implementing the technical content. Bob said that sending the BIRD to the editorial group could delay the process. Walter clarified that he was not asking to schedule a vote, but to untable the BIRD for discussion at the next Open Forum meeting. There was no objection to that. Michael noted that members who have not read the BIRD should prepared for discussion at the next meeting. AR: Arpad will email ibis@eda.org to announce that BIRD 123.2 will be open for technical discussion. Michael Mirmak cautioned against implying any exact vote date. Bob said there would be no harm in reviewing the BIRD now. BIRD124: IBIS-AMI NEW RESERVED PARAMETERS FOR DEPENDENCY TABLES Discussion was tabled. BIRD125.1: MAKE IBIS-ISS AVAILABLE FOR IBIS PACKAGE MODELING Discussion was tabled. BIRD128: ALLOW AMI_PARAMETERS_OUT TO PASS AMI_PARAMETERS_IN DATA ON CALLS TO AMI_GETWAVE Discussion was tabled. BIRD129: ADD “POLARITY” ARGUMENT TO D_TO_A CONVERTERS Discussion was tabled. BIRD 131: IBIS-AMI REPEATERS Discussion was tabled. BIRD144.3: ADD TOUCHSTONE TO [EXTERNAL MODEL] AND [EXTERNAL CIRCUIT] AS A SUPPORTED LANGUAGE Discussion was tabled. BIRD145.2: CASCADING IBIS I/O BUFFERS WITH [EXTERNAL CIRCUIT]S USING THE [MODEL CALL] KEYWORD Discussion was tabled. BIRD147: BACK-CHANNEL SUPPORT Discussion was tabled. BIRD150: IBIS-AMI NEW RESERVED PARAMETERS FOR DEPENDENCY TABLES Discussion was tabled. IBISCHK5 BUG STATUS Michael Mirmak reported on a new pending IBISCHK BUG133 “IBIS-AMI Program Bug or Missing Error with Spurious Words”. Bob Ross explained that words not enclosed in parentheses cause various problem outcomes. Bob said we must clean up parsing of the tree structure, hopefully in the next parser release. BUG133 was classified as moderate severity, high priority, and open status. There were no objections to the classification. Michael noted that we have 8 open bugs. Bob said all but BUG132 are related to IBIS-AMI and should be closed in the next parser release. BUG132 might also be fixed but there is no commitment to that. Radek Biernacki said that global symbols in the source code require a certain amount of adaptation to use it. Reducing those would make the source code easier to use without modification to avoid namespace issues. Michael said this could be included in the next parser scrub, but it might not be classified as a bug. He noted that putting it on the bug list might help to track it however. Bob mentioned that several years ago a person from Agilent Technologies submitted a list of suggestions for improving ibishck5. Bob also noted that we do have the enhancement bug category. Bob reported that the parser developer has been working on IBIS 5.1 changes, including weak tie-up/tie-down enhancements and the test keyword changes, as well as a number of other approved BIRDs. The 5.1 reformat is not a gating factor for parser work. Bob will ask for estimates on completion date. Bob noted that this work is being done under a prepaid contract. About 20 BIRDs are involved, plus the bug list. TSCHK2 ISSUE Bob reported that the recent tschk2 bug required only a recompilation to fix. Radek Biernacki looked into this. Radek, Eckhard Lenski and Mike LaBonte have helped to test the fix. Michael Mirmak asked if a revision number change is required. Bob suggest not doing that. Radek agreed, but suggested having a README comment to explain the update. NEW TECHNICAL ISSUES None. NEXT MEETING The next IBIS Open Forum teleconference will be held April 20, 2012 from 8:00 to 10:00 AM US Pacific Time. Michael Mirmak also noted May 16 would be a Summit meeting date in Europe. Mike LaBonte moved to adjourn. Arpad Muranyi seconded. There were no objections. ======================================================================== NOTES IBIS CHAIR: Michael Mirmak (916) 356-4261, Fax (916) 377-3788 michael.mirmak@intel.com Data Center Platform Applications Engineering Intel Corporation FM5-239 1900 Prairie City Rd., Folsom, CA 95630 VICE CHAIR: Lance Wang (978) 633-3388 lwang@iometh.com President/CEO, IO Methodology, Inc.
