The minutes were approved without changes or objections. WEB PAGE UPDATES Syed Huq reported that the FAQ page has been updated and the changes to the Roster are in progress, as membership renewals are received. MAILING LIST ADMINISTRATION Bob Ross reported that the list is running normally. MODEL LIBRARY UPDATE Lance Wang reported no new library models. PRESS UPDATE Bob Ross noted that a new article on IBIS and SERDES interfaces by Steve Kaufer was published in the July 2007 edition of Printed Circuit Design and Manufacture. The article, "High frequency digital signals require complex models to accurately simulate the signal’s path," is available at: http://pcdandm.com/cms/cms/content/view/3616/95/ MISCELLANY/ANNOUNCEMENTS None. OPENS FOR NEW ISSUES None. INTERNATIONAL/EXTERNAL PROGRESS Upcoming conferences of interest to IBIS members are listed below. SSP, the IEEE Statistical Signal Processing Workshop, is to be held August 26-29, 2007 in Madison, Wisconsin. The deadline for paper submissions has passed. More information can be found at: http://ssp07.org/ The 6th International Workshop on Electromagnetic Compatibility of Integrated Circuits (EMC Compo 2007) is to be held November 28-30, 2007, in Torino, Italy. More information can be found at: http://www.emccompo07.polito.it/ Bob also noted that Roy Leventhal updated the TC10 standards committee on IBIS Open Forum efforts to revise Touchstone. IEC APPROVAL ACTIVITIES No updates. SUMMITS - Asian IBIS Summit (China) Planning The Asian IBIS Summit (China) will be held Tuesday, September 11 at The Park Plaza Science Park hotel in Beijing. Bob Ross and Lance Wang are contacts for attendees and presenters. The first, second and third calls for papers have been distributed. Financial arrangements are nearly finalized. Official sponsors so far include Huawei Technologies, Agilent, Ansoft, Cadence, Intel, Mentor Graphics, Sigrity, SiSoft, Synopsys and ZTE Corporation. Spaces still exist for presentations and commitments as early as possible are appreciated. - Asian IBIS Summit (Japan) Planning The Asian IBIS Summit (Japan) will be held Friday, September 14 at JEITA headquarters in Tokyo. Sponsors include Agilent Technologies, ATE Service Corporation, Cadence Design Systems, Cybernet Systems and Mentor Graphics. The other official sponsor of the Japan summit is JEITA with others to be determined. The second announcement is scheduled for distribution July 13. Bob is the main contact for this event. Sponsorship opportunities for the Asian IBIS summits are available, with sponsors receiving free mentions in the minutes, agenda, and other announcements. Contact the IBIS Board for further details. Michael Mirmak reported that two separate companies had requested, during his recent trip to Asia, that future summits be held in Taiwan, Singapore or Malaysia. It is difficult for companies in Taiwan to get visas to attend the mainland China summit. A local event would be much more convenient. In addition, companies further from Japan and mainland China tend not to attend the events there, due to the distances involved. Bob Ross noted that the events should be held relatively closely in time, to permit presenters and board members to attend all of them with reduced travel expenses. Anders Ekholm observed that running several summits in close time proximity would still mean that board participants would spend several weeks away from their home offices. The attendees agreed that an additional September event would not be feasible. However, an additional location for the fall of 2008 will be considered, with perhaps an exploratory event earlier in the year. IBIS QUALITY TASK GROUP Mike LaBonte reported that the team is continuing to analyze the [Model] section of the IBIS specification. This is expected to take some time. The Quality Task Group checklist and other documentation can be found at: http://www.eda-stds.org/ibis/quality_wip/ IBIS MODEL REVIEW TASK GROUP No update. ADVANCED TECHNOLOGY MODELING TASK GROUP Arpad Muranyi reported that meetings will resume shortly with both updates to the BIRD as well as potential test examples being prepared for review. Task group material can be found at: http://www.eda-stds.org/ibis/macromodel_wip/ AD HOC TASK GROUPS (INTERCONNECT) Michael Mirmak reported that the group has not met recently, due to holidays and travel. However, meetings will soon resume, considering IIRD9 (updates to ICM) and IBIS-to-ICM links after that. Task group material, including the Touchstone2 draft specification, can be found at: http://www.eda.org/ibis/adhoc/interconnect/ NEW ISSUES None. IBISCHK4 BUG STATUS Bob Ross noted that IBISCHK4 version 4.2.2 executables had been prepared for several operating systems, and that feedback has been positive from the testers. Without objection, the attendees agreed to distribute the IBISCHK4 version 4.2.2 parser as soon as executables were available for the common operating systems supported under previous releases. Bob added that the 4.2.2 parser closes all open BUG reports. ICMCHK1 BUG STATUS No update. BIRD98.1: GATE MODULATION EFFECT (TABLE MODEL) Antonio Girardi thanked Bob Ross for his detailed comments on the BIRD text, noting that most of the suggested changes could be easily made. Additional discussion is still needed on issues related to measuring effective current for different output voltages. A new draft of the BIRD is being prepared. PROPOSED TOUCHSTONE2 SPECIFICATION INTRODUCTION Michael Mirmak presented a detailed overview of the proposed changes to the Touchstone specification. The need for an update to the specification was noted, at a high level, and the new keywords and features were presented. Most new features enable new applications, such as combined power and signal network extraction, using keywords similar to IBIS. Michael emphasized that the new version of Touchstone does not invalidate existing files. Instead, all existing Touchstone files that conform to the original specification will be considered legal and valid under the revised version. Only if the files use new keywords or features do the new rules become requirements. Bob Ross inquired whether the [Reference] keyword can “wrap” across multiple lines. Michael responded that this was the intent of the text, but may not have been clear. Zhiping Yang also asked about the new specification’s support for mixed-mode S-parameters, in the format commonly used today for the original Touchstone. Michael answered that this data would not be automatically parsed as mixed-mode, and that comments would be needed in the new version to inform users of the mixed-mode nature of the data. Arpad Muranyi asked about the removal of normalization. This was intended as a simplification, to reduce confusion once multiple port reference impedances were added. The team suggested some additional actions related to version numbers and parser development, including clarification of the number “2” in the name and the version number. These will be discussed with the GEIA in greater detail while the technical issues are being handled. Sam Chitwood made a number of suggestions for improvement, intended to reduce file sizes in data sets for large numbers of ports. These included: - supporting an upper-half or lower-half matrix format for passive interconnects - supporting a binary representation at the specification level - adding a keyword to explicitly state the number of frequency points in the file Sam explained that higher frequency points may sometimes be questionable in terms of validity, and that tedious hand-editing is often needed to remove this data. An explicit keyword would provide an implicit “bandwidth” that tools and users could adjust dynamically to exclude data. Bob noted that this would also help as another internal checking device for proper syntax. Michael inquired about interpolation and sampling intervals being named in the file, as some proprietary interconnect matrix models do. Sam responded that this may not be simple or desirable. Michael noted that this presentation represented the first “call for comments” for the draft, for standardization voting. These suggestions could easily be worked into an updated draft, for consideration by the Open Forum during upcoming meetings.

OPEN ISSUES None. NEXT MEETING The next IBIS Open Forum teleconference will be held August 3, 2007 from 8:00am to 10:00am US Pacific Time. ======================================================================== NOTES IBIS CHAIR: Michael Mirmak (916) 356-4261, Fax: (916) 377-3788 michael.mirmak@intel.com Server Platform Technical Marketing Engineer, Intel Corporation FM5-239 1900 Prairie City Rd.
