Several attendees noted issues with connecting to WebEx, and at least one attendee was never able to connect. 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 or ICM 1.1 specifications. No patents were declared. REVIEW OF MINUTES AND ARS Randy Wolff called for comments regarding the minutes of the February 21, 2014 IBIS Open Forum teleconference. The minutes were approved without changes. ANNOUNCEMENTS Michael Mirmak announced that he had new IEEE updates to share, and these were already listed on the agenda. CALL FOR ADDITIONAL AGENDA ITEMS None. MEMBERSHIP STATUS AND TREASURER'S REPORT Bob Ross reported that the treasury sits at $24,181. 11 members have renewed so far for 2014. Bob took an AR to start reminding members of renewals. Michael Mirmak asked if our target is still about 28-30 members. Bob noted that he pushed back on Chris Denham to see if 22 members are enough to break even. We had that many last year. Mike LaBonte asked if the renewal email would have come from SAE. Michael responded that the email was sent from Rita Gerber, and it should have an invoice attached. WEB PAGE AND MAILING LIST ADMINISTRATION Mike LaBonte had no web page items to report. Concerning email, one person reached Mike through Lance Wang. Emails from the person were not reaching ibis*@eda.org. Anyone can contact Mike at mike@labonte.com if they are not seeing emails sent to the ibis reflectors go through. MODEL LIBRARY UPDATE No update. Mike LaBonte noted that the library was updated recently and all the links were checked for validity. 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. - New IEEE Standards Michael Mirmak reported seeing a press release at the end of February about the formation of IEEE working groups P2401 and P1666. These groups are officially known as the SystemC Analog/Mixed-Signal (AMS) Extensions working group and the LPB - Standard Format for Large Scale Integration (LSI)-Package-Board Interoperable Design working group. Both groups do technical work in EDA standards development. The press release is linked at: http://www.businesswire.com/news/home/20140226005029/en/IEEE-Forms-Working-Groups-Standardize-Steps-Electronic#.UyMf59XnbvU Michael also noted that the IEEE P1735 working group that works on encryption is active. They are in the testing and implementation stage of the standard development. Mike LaBonte asked what IBIS' most recent interest in encryption was. Michael responded that there was a hurdle to IBIS 4.1 AMS language adoption if the model contained IP and couldn't be encrypted. There was some thought that P1735 could be used with the AMS languages. It could be extended to Spice macromodels potentially. Mike asked if there is anything we'd need to do once the standard is finished. Michael felt that we'd need to see if anything in IBIS 4.1 would need to change to support encryption. SUMMIT PLANNING AND STATUS - European IBIS Summit Status The Summit is scheduled after the SPI event on May 14, 2014 in Ghent, Belgium. The first call for papers will go out next week. Randy Wolff noted that he is planning to attend, so if no other officers can attend, he can run the meeting. Michael Mirmak noted that sponsorships are welcome. - 2014 Summit schedule DAC is June 1-5, 2014 in San Francisco, CA. Michael Mirmak contacted DAC organizers to see about potential co-sponsorships with DAC. Most deadlines have passed, but he does have contact information for next year. So, we'll probably make use of a room reserved by one of our member organizations. 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 there is ongoing activity to finish the ibischk program documentation. He is hoping to complete the document for release along with the next ibischk version. The group is meeting on an as-needed basis during the Tuesdays at 8:00 a.m. PT time slot. If anyone is interested in attending, look for the meeting notices the day before. 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 currently discussing BIRD147 on backchannel modeling. There was discussion about starting up an interconnect modeling meeting to have additional time for discussion of package modeling. Bob Ross commented that he is working with Ambrish Varma on the backchannel BIRD and is simplifying it. There will be technical and editorial changes to present at the next meeting. Michael Mirmak asked if there would be additional follow-up to discuss PCI express or other interfaces that require backchannel modeling. Arpad did not have any information about these interfaces. Michael noted that he may have additional experts available to present on these interfaces. Task group material can be found at: http://www.eda.org/ibis/macromodel_wip/ NEW ADMINISTRATIVE ISSUES Michael Mirmak noted that the Interconnect task group will be restarted next week for discussions of package modeling. Let him know if you are interested in attending and were not previously on the task group's mailing list. 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. IBISCHK6 PARSER STATUS Bob Ross reported that the developer has implemented all the BIRDs except BIRD160 so far and is planning to share the code with him. Any paid parser owner is free to look at the code drop. Bob noted that some issues with IBIS 6.0 have been discussed recently. He requested Michael Mirmak to create a known issues list on the website. NEW TECHNICAL ISSUES Michael Mirmak noted that many EDA vendors expressed concerns with the IBIS specification being released every 6 months. He thinks we should discuss going to a one year release schedule instead of a 6 month release schedule. NEXT MEETING The next IBIS Open Forum teleconference will be held April 4, 2014 from 8:00 a.m. to 10:00 a.m. US Pacific Time. The following meeting will be held April 25, 2014. Radek Biernacki 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.
