CALL FOR PATENTS Michael Mirmak called for any patents or pending patents related to the IBIS 3.2, IBIS 4.2, IBIS 5.1, Touchstone 2.0 or ICM 1.1 specifications. No patents were declared. REVIEW OF MINUTES AND ARS Randy Wolff called for comments regarding the minutes of the November 9, 2012 IBIS Summit – Shanghai, the November 13, 2012 IBIS Summit – Hsinchu, the November 16, 2012 IBIS Summit – Yokohama and the November 30, 2012 IBIS Open Forum teleconference. All sets of minutes were approved without changes. MEMBERSHIP STATUS AND TREASURER'S REPORT Bob Ross reported that there is no change from last time. We currently have 29 members. There will be 28 members carried over into 2013 as we officially drop Sigrity. TechAmerica will be sending invoices for membership renewal in January. Bob mentioned that there are still some financial transfers related to the China summit that need to be resolved with TechAmerica. We are trending to have a surplus of funds this year from parser payments. WEB PAGE UPDATES Mike LaBonte reported that a DesignCon banner was added near the top of the home page as part of honoring our contract with UBM for DesignCon co- sponsorship. MAILING LIST ADMINISTRATION Mike LaBonte reported that we are required to send out three HTML formatted emails to the membership lists as advertising for DesignCon. These will go out at the same time as the IBIS Summit call for participation emails. There is still ongoing debug related to issues Walter Katz is having with emailing the eda.org mailing lists. Michael Mirmak asked about any official recommendations for email formats such as rich text or HTML for our emails, since he noticed formatting issues with emails on the various lists. Mike asked that someone forward him any emails they have sent to the list in rich text or HTML format that do not come through the lists properly. Michael noted that the UBM email about DesignCon will be a good test, since it is in HTML format. MODEL LIBRARY UPDATE No update. MISCELLANY/ANNOUNCEMENTS None. CALL FOR NEW ISSUES Bob Ross requested time for discussion of BUG140. BUG, BIRD AND OTHER REPORTING VIA WIKI Michael Mirmak noted that Mike LaBonte has looked into alternatives to Mantis for bug and BIRD tracking. Mike reported that he doesn’t have access to a BugZilla server (one with Perl CGI) to fully test BugZilla on. He has been investigating DokuWiki, a non-SQL based wiki engine. He showed a DokuWiki home page that looked very similar to the current IBIS homepage. A search box allows searching for content within any wiki pages. He used an HTML to DokuWiki conversion program on the Summits page to show the ease of conversion of the current pages to the DokuWiki format. Mike logged in to show further functionality. He demonstrated editing the Summit files page to add a new document. Michael asked about permissions for editing the page such as for submitting BIRDs. Mike responded that there are at least two levels of editing access available that would allow people to edit specific pages. Michael wondered if this type of editing would be too difficult for average users wanting to just report new bugs. Mike showed how anyone could submit a bug report through a form, and then an administrator would need to add the information to the bug list page. Mike will add some logins to the site he has created and let a few more people test its functionality. He’ll need to look into having write permissions on files at the group level but not for everyone. INTERNATIONAL/EXTERNAL ACTIVITIES - IEEE DASC Michael Mirmak reported that there was a meeting in early December but no IBIS related topics were addressed. The monthly meeting schedule will restart in early January. - VHDL-AMS Table-Driven Models Arpad Muranyi requested this item be removed from our next agenda. - Conferences The 17th IEEE Workshop on Signal and Power Integrity (SPI 2013) will be held May 12-15, 2013 in Paris, France. There will probably be a European IBIS Summit in conjunction with this conference. More information is available at: http://spi2013.org - Press Update Michael Mirmak noted a paper from the IEEE Transactions on Device and Material Reliability titled “Investigation of Modeling System ESD Failure and Probability Using IBIS ESD Models”. In this paper, a behavioral modeling methodology to predict ESD failures at system level is proposed and validated. The authors are from the LAAS laboratory in Toulouse, France. The article can be found in the IEEE Xplore library at: http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6301685 IEC APPROVAL ACTIVITIES Randy Wolff reported that a TC91 meeting was held October 15-19 in Fukuoka- city, Japan. He was able to get the meeting minutes from Victor Berman. The minutes showed that WG13 has responsibility for maintenance on the IBIS specification (IEC 62014-1). Dennis Brophy was listed in the minutes as a co-convener of WG13. Randy sent Dennis an email last week to inquire further about the WG13 meeting and find out how to help the process. He has not gotten a response yet. Michael Mirmak requested that Randy send an email to Chris Denham at TechAmerica to notify him of the IEC progress. SUMMIT STATUS -DesignCon 2013 Summit Status Michael reported that the Summit meeting will be Thursday, January 31 in the Mission City M1 room from 8:30am - 5:30pm. We are open to co- sponsorship. Michael encouraged presentations and asked that any presentations be made available one week in advance. Also, a 20% discount is available to IBIS participants for any DesignCon passes, available only through December 31. Lance Wang is the main contact for registrations. Mike LaBonte noted that the UBM email contains a direct link to the IBIS discount, even though our own emails have not included a direct link. Bob Ross thought the contract was a discount only for IBIS members, so we need to check this before sending out the UBM email. Michael also needs to check on the size of the room to see if we are limited in attendance. Sponsorship opportunities for all upcoming IBIS summits are available, with sponsors receiving free mentions in the minutes, agenda, and other announcements. Contact the IBIS Board for further details. QUALITY TASK GROUP Mike LaBonte reported that he and Bob Ross helped Cadence file BUG140, and they discussed whether this BUG should be a Caution, Note, Warning or Error. He noted that there aren’t clear policies on what constitutes these levels, so they are working on a policy document to better define the four classifications of bugs. Tuesday, January 8 at 8:00am PT is the next meeting. They will be working on more specification documents for the parser. The Quality Task Group checklist and other documentation can be found at: http://www.eda.org/ibis/quality_wip/ ADVANCED TECHNOLOGY MODELING TASK GROUP Arpad Muranyi reported that the group is meeting regularly on Tuesdays. The next meeting is January 8, 2013. Discussions are getting into stalemate situations because everything seems to depend on decisions made about analog modeling. Discussions will focus around analog modeling to try to resolve the challenges there. Task group material can be found at: http://www.eda.org/ibis/macromodel_wip/ INTERCONNECT TASK GROUP Michael Mirmak reported that the group continues to meet Wednesdays. The next meeting is January 9, 2013. The most recent topic of discussion focused on details of where interconnect and analog modeling issues tie together. They are also looking at pending BIRDS related to analog modeling and whether they need to be voted up or down. The task group documents can be found at: http://www.eda.org/ibis/interconnect_wip/ NEW ADMINISTRATIVE ISSUES None. BIRD155: NEW AMI API TO RESOLVE DEPENDENT MODEL PARAMETER Radek Biernacki introduced the BIRD. This BIRD is considered an alternative to BIRD150. Discussions in the ATM task group led to this BIRD. The BIRD defines new arguments to the DLL that will process the information and set other dependent parameters. This gives the functionality of setting dependencies within the DLL. Randy Wolff noted a typo in the AMI_ResolveDependentParam name, and Bob Ross noted a semicolon that could be removed from the function declaration. David Banas asked if the dependency is bi-directional to allow flow of dependencies from the DLL to the simulator. Radek said there could be bi- directional flow, so one needs to be careful with circular dependencies. Walter Katz noted that this BIRD is a different way of doing the same thing as BIRD150. He noted that the BIRD150 writers originally rejected the methods shown in BIRD155, and further discussion of pros and cons will need to ensue in the ATM task group. Significant input from model makers is needed about which method is preferred. Bob noted a concern with this BIRD, where he is confused about if “In” really means input or independent. Walter and Radek felt the usage was well described. Walter moved to table this BIRD and move the discussion to the ATM task group. Bob seconded the motion. There were no objections. BIRD121.2: IBIS-AMI NEW RESERVED PARAMETERS FOR DATA MANAGEMENT Walter Katz moved to schedule the BIRD for a vote at the next teleconference. Arpad Muranyi seconded the motion. There were no objections. BIRD123.4: IBIS-AMI NEW RESERVED PARAMETERS FOR JITTER/NOISE Walter Katz moved to schedule the BIRD for a vote at the next teleconference. Bob Ross felt that the BIRD needed a change to fix an issue with Tx_Jitter, where the BIRD makes a change in one place in the specification but not another, and it could lead to a contradiction. In response to Michael Mirmak, Bob didn’t think the change would preclude scheduling a vote. He plans to work on another revision and submit it for review before the next meeting. Radek Biernacki had seconded the motion but retracted his second based on wanting to make sure the BIRD changes had enough time for review. David Banas seconded the motion. There were no objections. BIRD123.4 or BIRD123.5 (if submitted two weeks before the next teleconference) will be eligible for a vote at the next teleconference. BIRD116.1: ADD IBIS-ISS TO [EXTERNAL MODEL] AND [EXTERNAL CIRCUIT] AS A SUPPORTED LANGUAGE Discussion was tabled. BIRD117.4: PARAMETERIZE A_TO_D AND D_TO_A CONVERTERS Discussion was tabled. BIRD118.3: ANALOG PARAMETER ASSIGNMENTS Discussion was tabled. BIRD122: IBIS-AMI NEW RESERVED PARAMETERS FOR ANALOG MODELING 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. BIRD153: PARAMETER TREE KEYWORD Discussion was tabled. BIRD154: USING IBIS-AMI LEAF LABELS IN LIST PARAMETERS Discussion was tabled. IBIS SPECIFICATION CHANGE STATUS Michael Mirmak showed a new revision of the document. He noted that more BIRDs are being submitted using the new template. A template version 1.2 has been posted, so this should be used for new BIRD submissions. The document is available at the following link: http://www.eda.org/ibis/docs/ibis-version-change-strategy-v2p4.pdf IBISCHK5 BUG STATUS Bob Ross noted that BUG140 was classified in the last meeting, but a fix was not resolved. The BUG describes problems with non-monotonicity when adding together clamp curve I-V data to Pullup or Pulldown I-V data. The issue is annoying because no model developer wants to release models that have Warning messages from the parser for non-issues. One fix is to downgrade the Warning to a Note and add a statement that the problem exists when using piece-wise linear interpolation. Mike LaBonte added that he’d still like to see warnings for large non-monotonicites, but the situation he is describing is probably not related to this bug. Walter felt that Bob’s recommendation of downgrade to a Note would work fine. Michael Mirmak reported that there is actually a mention in the IBIS 5.1 specification that the parser will only check individual I-V tables for non- monotonicities and not combined tables. We may need to write a BIRD to remove this text from the specification, as we shouldn’t have parser specification statements in the IBIS specification. NEW TECHNICAL ISSUES Walter Katz gave a summary of the analog issues being talked about in the task groups. One issue is the need for an IBIS-ISS interface for on-die interconnects. The second issue is the definition of the correct model to use for IBIS-AMI buffer modeling. There are issues with using the current [Model] or [External Model] implementations. With the addition of [External Model] in IBIS 4.1, the D_to_A converter only added capabilities for the buffer to be in a high, low, or transition state. SerDes buffers drive at multiple levels depending on tap coefficients. Arpad Muranyi noted that this kind of multi-level driver is a multi-tap driver that has multiple legs, or taps controlled by the EQ logic and whose drive strength is changing depending on the bit pattern. This is different from multi-level PAM4 drivers and we shouldn't confuse the two. Arpad added that the biggest question that needs to be settled whether the input of the IBIS [Model] is considered a digital or analog signal. Discussion was cut off as the meeting ended. Michael Mirmak suggested that this topic be discussed at the next ATM task group meeting. NEXT MEETING The next IBIS Open Forum teleconference will be held January 11, 2013 from 8:00am to 10:00am US Pacific Time. Votes on BIRD121.2 and BIRD123.4 are scheduled for this meeting. Bob Ross noted that Mike LaBonte will need to check on the availability of using the Cisco conference bridge in 2013. Mike though the bridge did not have an expiration date but would check on it. Radek Biernacki moved to adjourn. David Banas 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.
