CALL FOR PATENTS Michael Mirmak called for any patents or pending patents related to the IBIS 3.2, IBIS 4.2, IBIS 5.1, IBIS 6.0, Touchstone 2.0, IBIS-ISS 1.0 or ICM 1.1 specifications. No patents were declared. REVIEW OF MINUTES AND ARS Randy Wolff called for comments regarding the minutes of the March 14, 2014 IBIS Open Forum teleconference. The minutes were approved without changes. ANNOUNCEMENTS None. CALL FOR ADDITIONAL AGENDA ITEMS None. MEMBERSHIP STATUS AND TREASURER'S REPORT Bob Ross reported that 14 members have renewed so far for 2014. The treasury sits at $26,880. There is a potential Touchstone parser pending. He sent reminder emails to active members that have not renewed yet. He got some responses, so he expects more renewals soon. He reminded members to renew before the DAC Summit meeting to maintain membership status for 2014. WEB PAGE AND MAILING LIST ADMINISTRATION Mike LaBonte reported there are 409 unique email addresses across both mailing lists. Web page updates were made to the events page for the DAC Summit event. Lynne Green has offered to donate her training materials for IBIS training. She needs to do some reformatting before it can be posted, but she expects that to be done in May. Mike plans to implement it in the wiki and link it in to the main page. This will be the first content solely on the wiki page. Michael Mirmak clarified that her company is Green Streak Programs. His understanding is that she is not planning to continue the training classes in the future. We should mention her prominently on the web page. Michael also thought it would be good to turn the IBIS cookbook into a wiki site. MODEL LIBRARY UPDATE Anders Ekholm noted that he had made no updates since the last meeting. The last updated added one company, removed two or so and fixed several broken links. INTERNATIONAL/EXTERNAL ACTIVITIES - Conferences The 18th IEEE Workshop on Signal and Power Integrity (SPI 2014) will be held May 11-14, 2014 in Ghent, Belgium. There will be a European IBIS Summit in conjunction with this conference. There are typically many papers on IBIS-related algorithms presented by student researchers. More information is available at: http://spi2014.org - Press Update None. SUMMIT PLANNING AND STATUS - European IBIS Summit Status The Summit is scheduled after the SPI event on May 14, 2014 in Ghent, Belgium. Bob Ross noted that the second announcement needs to go out. Michael Mirmak is planning to send it out after the meeting. Bob clarified that the event will be a half day. Zuken is confirmed as one of the co-sponsors. Attendees are encouraged to sign up and submit paper presentations. - 2014 Summit schedule DAC is June 1-5, 2014 in San Francisco, CA. Michael Mirmak reported that room space is confirmed with the help of John Angulo of Mentor in the Moscone Center co-located with DAC. We also have been registered officially on the DAC website. To use the room as part of DAC, there is a requirement to have a DAC attendance badge. A free badge (called "I Love DAC") is available until May 15, so Summit attendees will need to register with DAC by that time. We are planning for 20-30 people, but with co-location with DAC, we may get more attendees. 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 the group's current task is to complete the ibischk5 parser documentation. They are documenting the list of messages, what they mean and what causes them. The pressure is on to finish this in a week or two. They also discussed a Touchstone bug recently. 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 at 12:00 p.m. PT. They are recently discussing BIRD147 on backchannel modeling. The BIRD is getting more changes to include a statistical flow. Task group material can be found at: http://www.eda.org/ibis/macromodel_wip/ INTERCONNECT TASK GROUP Michael Mirmak reported that the group held its second meeting last week. Package model examples supplied by Randy Wolff have been written up in two different proposals from Arpad Muranyi and Walter Katz. Comparisons in syntax are ongoing. Michael won't be able to attend the next meeting, so Mentor and SiSoft will be helping host the meeting. Mike LaBonte will send out a WebEx invite and Arpad will provide the phone bridge. The group is meeting Wednesdays at 8:00 a.m. PT. NEW ADMINISTRATIVE ISSUES Michael Mirmak reported that he was notified we will get additional information on SAE's ITC rules that allow us to maintain our entity-based membership. 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. BIRD145.3: CASCADING IBIS I/O BUFFERS WITH [EXTERNAL CIRCUIT]S USING THE [MODEL CALL] KEYWORD Discussion was tabled. BIRD147: BACK-CHANNEL SUPPORT Discussion was tabled. BIRD157: PARAMETERIZE [DRIVER SCHEDULE] Discussion was tabled. BIRD158.3: AMI TOUCHSTONE ANALOG BUFFER MODELS Discussion was tabled. BIRD161.1: SUPPORTING INCOMPLETE AND BUFFER-ONLY [COMPONENT] DESCRIPTIONS Discussion was tabled. BIRD163: INSTANTIATING AND CONNECTING [EXTERNAL CIRCUIT] PACKAGE MODELS WITH [CIRCUIT CALL] Discussion was tabled. BIRD164: ALLOWING PACKAGE MODELS TO BE DEFINED IN [EXTERNAL CIRCUIT] Discussion was tabled. BIRD165: PARAMETER PASSING IMPROVEMENTS FOR [EXTERNAL CIRCUIT]S Discussion was tabled. IBISCHK5 PARSER AND BUG STATUS Bob Ross reported there are no new bugs. BUG147, BUG148 and BUG149 will be fixed in the ibischk6 release. Michael Mirmak noted that BUG150 is classified as not a bug, so it doesn't need to be dealt with. BUG151 will remain open for now. IBISCHK6 PARSER STATUS Bob Ross reported that he has an initial partial code release including all BIRDs for IBIS 6.0 except BIRD160.1. He and Michael Mirmak have reviewed test cases and noticed a Type issue for three AMI Reserved Parameters. It was found that descriptions of the parameters were correct but the tables were incorrect. The developer had implemented checking based on the tables, so a code fix is in progress. A few other minor incorrect implementations are being fixed. None of the bug fixes were incorporated in this release. Michael noted that a BIRD is needed to clarify the table fixes for the Reserved_Parameter Type issue. He is working on the BIRD. Bob asked if a null root was allowed in the .ami file. Mike LaBonte thought this should not be allowed. David Banas and Radek Biernacki both recollected that a root name is required. Bob noted that if this is the case, then the parser test cases need to updated to include root names. The parser currently doesn't check for this condition. The targeted release is still May 15. KNOWN ISSUES LISTING FOR VER. 6.0 Michael Mirmak reported that a new document has been included on the website that lists known issues with the IBIS 6.0 specification. Issues can be editorial or technical and may or may not require BIRDs. Radek Biernacki asked if a BIRD was required for fixing the AMI tables that omit Type "Float" for Tx_jitter, Tx_Dj, Tx_Rj and Tx_Sj. He saw the correct tables in the original BIRD123. Bob Ross noted he felt this was the best way to deal with it. The document is linked at: http://www.eda.org/ibis/ver6.0/ver6_0_known_issues.txt IBIS ANNUAL UPDATE SCHEDULE DISCUSSION Michael Mirmak noted that comments were made at the last Summit meeting that the proposed 6-month release schedule for IBIS would be difficult to implement by EDA software vendors. More people expressed interest in a one year release schedule. Michael proposed moving to a one year release schedule, and he can prepare a slide for the next meeting detailing the schedule. Radek Biernacki felt this was a better proposal. Michael noted that further discussion will need to happen to agree on the new schedule and propose a cut-off date for BIRD submissions for the next IBIS release. NEW TECHNICAL ISSUES Walter Katz noted that he submitted a BIRD to Michael Mirmak that needs distribution on the IBIS reflectors. NEXT MEETING The next IBIS Open Forum teleconference will be held April 25, 2014 from 8:00 a.m. to 10:00 a.m. US Pacific Time. The next IBIS Open Forum Summit meeting will be held May 14, 2014 at SPI. There will be no teleconference. The following teleconference meeting will be held May 16, 2014. Bob Ross moved to adjourn. Arpad Muranyi seconded the motion. 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.
