CALL FOR PATENTS Bob Ross 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. MEMBERSHIP UPDATE AND TREASURER'S REPORT Bob Ross reported that 22 members have officially renewed. He is following up with several more members. Another ibischk5 parser license has been sold. This makes 9 parser sales so far. A Touchstone parser sale is being closed as well. REVIEW OF MINUTES AND ARS Bob Ross called for comments regarding the minutes of the April 2, 2010 IBIS Open Forum teleconference. The minutes were approved without changes. WEB PAGE UPDATES Bob Ross noted that an ‘upcoming teleconference’ link was added to the home page. Syed Huq reported that ‘Working Directories’ and ‘About IBIS’ links were added to the home page. All pages have moved to eda.org. He is still working to fix links on the Articles page. The eigroup.org page is now just a re-director to the eda.org site. Michael Mirmak asked in relation to the pages for individual task groups, is there an overhaul in progress for the quality or ATM site? Bob replied that he is not aware of any in progress. MAILING LIST ADMINISTRATION Bob Ross reported that there are still bounces related to the Stanford servers. MODEL LIBRARY UPDATE Anders Ekholm reported that the latest update was on April 7. He is working on another update for mid-May. Bob Ross asked if there were any further comments on crowd sourcing. Anders looked at the web page from Colin Warwick, but it was not obvious to him how it worked. He did not feel that enough IC vendors would be interested in updating a crowd sourcing page. Bob noted that there was interest in this concept from a poll conducted by Colin. PRESS UPDATE Bob Ross mentioned a book by Dave Coleman and Michael Mirmak titled Mastering High Performance Multiprocessor Signaling. The book includes one reference to IBIS. More information is available at: http://tinyurl.com/28dyozu MISCELLANY/ANNOUNCEMENTS Bob Ross noted that the DesignCon show has been taken over by EETimes. He is not sure what implications this will have for the conference. OPENS FOR NEW ISSUES Bob Ross noted that new parser BUGs, BUG115 and BUG116, will be discussed later in the meeting. INTERNATIONAL/EXTERNAL ACTIVITIES - DASC Michael Mirmak noted that the next meeting is two weeks from now. No content pertinent to IBIS was discussed in the last meeting. The DASC file and e-mail archive may be found at: http://www.dasc.org/ - P1735 Encryption No update. The IEEE Study Group on Encryption web reflector archives are found at: http://www.eda-stds.org/ip-encrypt/hm/ -Conferences Signal Propagation on Interconnects Workshop (SPI) is May 9 - 12, 2010 in Hildesheim, Germany. There is SI content and sometimes IBIS topics at this conference. The European IBIS Summit will be held in conjunction with this event on Wednesday afternoon. http://www.spi.uni-hannover.de/ TECHAMERICA STATUS No report. IEC APPROVAL ACTIVITIES Randy Wolff reported that he has had no further contact with Tim Rotti or Victor Berman. He is unsure who contact for further information at this point. SUMMIT STATUS -European Summit Planning The summit is planned for Wednesday, May 12 from 12:30pm-5:30pm. This is after the SPI conference, which ends at noon. It will be held at the same hotel and location as the SPI conference in Hildesheim, Germany. Ralf Bruening is helping with local arrangements. The third announcement went out including a preliminary agenda. 9 or 10 presentations are scheduled. 15 people are signed up so far. Some WebEx meeting time has been reserved as a backup in case there are travel delays related to the Iceland volcanic eruptions. Agilent, Mentor, Sigrity, Sintecs and Zuken are co-sponsors. -DAC Summit Planning The DAC summit is planned for Tuesday, June 15 in Anaheim, CA. Traditionally this meeting is the annual meeting with the election of officers. The first announcement will go out after the meeting. Lance Wang will handle the signups. Bob Ross noted that the exhibition is free on Monday. -Asian Summits Planning The planning committee is discussing three potential summits this year in China, Japan and possibly Taiwan. Lance Wang reported that he is working on the China summit. The meeting will be held the second week of November in Shenzhen. There is enough sponsorship committed including leftover funds from previous years, but he is asking more EDA vendors for sponsorship. Lance reported that there is a possibility of holding the first Taiwan summit this year. One sponsor has committed so far. Michael Mirmak added that there have been many requests to hold a summit in Taiwan. There are many sites in Taipei that could host the meeting. Michael will continue to press additional contacts for sponsorship. Travel between the mainland China and Taiwan is now possible directly without going through Hong Kong. Bob Ross reported that he needs to contact JEITA about a summit in Japan. 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. IBIS QUALITY TASK GROUP Bob Ross reported that the group is working on a correlation handbook. The Quality Task Group checklist and other documentation can be found at: http://www.eda.org/ibis/quality_wip/ IBIS MODEL REVIEW TASK GROUP No update. ADVANCED TECHNOLOGY MODELING TASK GROUP Arpad Muranyi reported that there was lively discussion this week about the AMI flow diagrams. There is much discussion on this topic. The clock times BIRD draft was finalized last week and will be up for a vote next week. More BIRDs are in the works to clarify text of the AMI specification. The BIRDs may all be combined into a single BIRD before submitting to the Open Forum for a vote. Task group material can be found at: http://www.eda-stds.org/ibis/macromodel_wip/ INTERCONNECT TASK GROUP Michael Mirmak reported that the group is meeting Wednesday mornings at 9AM PT. They are discussing a proposal for binary encoding for Touchstone. The group plans to discuss other topics for addition to the Touchstone 2.1 revision. Michael will be traveling next week, so Bob Ross will be chairing the meeting again. Task group material can be found at: http://www.eda.org/ibis/adhoc/interconnect/ NEW ISSUES None. TSIRD1 – SPARSE MATRIX MAPPING Bob Ross showed TSIRD1 for final review. This TSIRD proposes an index-pair mapping solution using two new keywords, [Number of Sparse Labels] and [Sparse Matrix Mapping]. This solution helps reduce file size by reducing the size of matrices with symmetries and zero values. Radek Biernacki noted that all the examples show the [Version] as 2.0, and this needs to be 2.1. Also, he found one instance where ‘element’ needed to be pluralized. Bob Ross will make these editorial changes. Radek motioned for a vote for inclusion of TSIRD1 in the next revision of the Touchstone specification. The TSIRD vote includes the minor editorial changes. Michael Mirmak seconded the motion. The vote passed with the following vote tally: Agilent: yes Cadence: yes Ericsson: abstain IBM: yes Intel: yes IO Methodology: yes LSI: yes Mentor: yes Micron: yes Nokia Siemens Networks: yes SiSoft: yes Teraspeed: yes A full description of TSIRD1 is found at: http://www.eda.org/ibis/tsirds/ and http://www.eda.org/ibis/tsirds/tsird1.0.pdf TSCHK2 BUG STATUS No BUGs to report. IBISCHK5 BUG STATUS Sergey Nikonchuk and Andrey Babintsev of Freescale submitted BUG115 related to the new [ISSO_PU] and [ISSO_PD] keywords. There are parser checks related to these tables. Currents are checked between these tables and the [Pullup] and [Pulldown] tables. The BUG found that mismatches were checked for min and max columns of data but not for the typ column. The BUG was classified as Severe severity, High priority and Open status. The same people also submitted BUG116. This BUG notes that the Warnings of mismatches (noted in BUG115) do not give enough significant digits to determine the severity of the mismatch. This BUG was classified as Severe severity, Medium priority, and Open status. Michael Mirmak noted that the titles of the BUGs need to be fixed to replace ‘{ }’ with ‘[ ]’ characters. Michael also noted that these issues of tolerances should be added to a parser specification. IBISCHK5 PROJECT Bob Ross noted that there are 9 open BUGs right now plus the two BUGs just added. A new project will be started to fix these BUGs. Bob has drafted a parser agreement, but it has not been reviewed yet. Michael Mirmak commented that it would be good for the parser developer to list the parser assumptions and associated tolerances used in the various parser checks. Bob noted that we should specify a tolerance for the BUG116 fix. NEW ISSUES Michael Mirmak asked if there was a method for reporting a Touchstone BUG. Bob Ross responded that we have a web page set up for this, but it is not linked in to the top level site yet. NEXT MEETING The European IBIS Summit will be held May 12, 2010 in conjunction with the SPI conference. No teleconference will be available. The next IBIS Open Forum teleconference will be held May 21, 2010 from 8:00 to 10:00 AM US Pacific Standard Time. ======================================================================== NOTES IBIS CHAIR: Bob Ross (503) 246-8048, Fax: (503) 239-4400 bob@teraspeed.com Staff Scientist, Teraspeed Consulting Group 10238 SW Lancaster Road Portland, OR 97219 VICE CHAIR: Lance Wang (978) 633-3388 lwang@iometh.com President / CEO, IO Methodology, Inc.
