REVIEW OF MINUTES AND ARS Randy Wolff called for comments regarding the minutes of the August 20, 2010 IBIS Open Forum teleconference. The minutes were approved without changes. MEMBERSHIP STATUS AND TREASURER'S REPORT Michael Mirmak reported that we still have 31 members. Bob Ross reported that we have a significant surplus of funds for the year due to six parser sales in 2010 as well as one extra member above the budgeted 30 members. The next step is to reconcile the account with TechAmerica. We will need to spend our surplus by the end of the year. Michael noted that we might be able to spend some money on further parser fixes. He is open to ideas for spending the surplus. WEB PAGE UPDATES Michael Mirmak noted changes to the IBIS Interconnect task group page to add minutes and presentations. Links to task groups were updated. The Futures group is now listed as inactive/archived. Bob Ross recommended moving some links off of the home page to clean it up and create an archives section. MAILING LIST ADMINISTRATION Mike LaBonte reported that he had 5 new subscribers since the last meeting. There are still issues with server reputation. Some users are still getting emails despite warnings from their email servers. Mike may announce in a future meeting how many emails were sent to the mailing lists so users checking the minutes will be able to cross reference the number of emails they have received. MODEL LIBRARY UPDATE No report. MISCELLANY/ANNOUNCEMENTS None. OPENS FOR NEW ISSUES None.

IBIS QUALITY TASK GROUP Mike LaBonte reported that they are working on a presentation for the upcoming summits including some information on the IEEE Feature Selective Validation. The next meeting is September 21. 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 the group has finished work on an AMI clarifications BIRD that has been submitted to the Open Forum. They are still working on the AMI flow BIRD and other AMI clarifications BIRDs. Task group material can be found at: http://www.eda-stds.org/ibis/macromodel_wip/ INTERCONNECT TASK GROUP Michael Mirmak reported that the group’s website has been updated with minutes and presentations. They are currently discussing MCP and IBIS-ISS on alternating weeks. The last meeting covered IBIS-ISS, and there will be a rev 0.6 of the document for the next meeting. A skeleton draft of the MCP proposal is being drafted as well. Task group material can be found at: http://www.eda.org/ibis/adhoc/interconnect/ NEW ISSUES None. BIRD113: WEAK PULL-UP AND WEAK PULL-DOWN RESISTANCE AND VOLTAGE Greg Edlund circulated an updated version of the BIRD after the last meeting. There have been discussions in the last few weeks on possible additions of a current source. Greg does not plan to make additional changes for this. Michael requested that Greg send him the BIRD113.1 revision for posting and review. This version includes some changes requested in the last Open Forum teleconference. Bob Ross noted that we still need to discuss the difference between a weak and strong termination. Walter Katz asked Greg to clarify that this BIRD does not change how models simulate and only adds information for checking purposes. Greg confirmed this is the case. BIRD114.1: IBIS-AMI DEFINITION CLARIFICATIONS Arpad Muranyi stated that the BIRD clarifies questions brought up by the parser developer. The 114.1 revision made minor changes to some examples to be consistent with the new definition that strings must be surrounded by double quotes. Bob Ross noted that BIRDs clarifying the AMI section are coming in piecemeal, and the whole section may need to be reorganized. He expressed concern about this editing process. Walter Katz added that he tried to propose last year that the whole section be re-written, and it was decided to re-write individual pieces instead. The Open Forum needs to recognize the best way to get a fixed AMI section completed. Walter thinks the real changes have been to the AMI document describing the AMI language and the AMI interface to the DLLs. He proposed that these should be separate documents taken out of the IBIS Specification and allowed to be revised separately and published in a format allowing for graphics. He also said that deprecation issues need to be clarified and addressed. Arpad Muranyi replied that BIRD114.1 and the final outcome of all of these future clarification BIRDs are conveying a technical clarification in the specification, and they are all overlapping. He sees that it is impossible in one BIRD or the other to give the final outcome of the specification language. He felt it was important to address small pieces incrementally in order to make progress. He thinks a careful editing process can be used to rewrite the final AMI section. Michael Mirmak asked if there was ever an approach discussed to address a few pages at a time. Arpad had not thought about that approach, but he did not think it would work. Walter noted that the organization of the document was not good, as terms are used before they are defined. Arpad added that he is trying to be very careful to keep track of the changes that will be required by adding notes to each of the BIRDs. Bob agreed with the current process, and his expectation is that before any release of an IBIS 5.1 specification, a thorough review of section 6c will be needed. Bob also feels that there should be an editorial committee. Walter made a specific request noting that there will be several BIRDs coming up from SiSoft, and he wants to write them without constraints of them being in the usual text format. This would be done with the understanding that formatting changes may be made in the future as required for inclusion in IBIS 5.1. The Open Forum will need to decide how to proceed with formatting of the full IBIS specification. Michael added that it would require a BIRD to remove a section from IBIS, but then the removed section could be treated like Touchstone 2.0 or ICM as a separate document. Bob asked about whether in BIRD114.1 a string can span multiple lines or if only a Description can span multiple lines. Walter noted that the Description definition is detailed so that EDA tools can display a text box with 120 characters of width. This does not exclude carriage return/line feeds in other strings. Anders Ekholm suggested that the BIRD clarify that control characters are allowed within strings. TSCHK2 BUG STATUS No BUGs to report. Michael Mirmak noted that the source code is available for purchase. IBISCHK5 BUG STATUS Bob Ross introduced BUG121. This BUG noted that a working test for a missing [Component] was corrupted in the IBIS 5.0.0 parser. The BUG was classified as Severe severity, Medium priority and Open status. IBISCHK5 UPDATE STATUS Bob Ross reported that he distributed a first cut of the new parser to a few people for review. IBIS-ISS STATUS Michael Mirmak reported that the document is being updated to Revision 0.6 and discussed in the Interconnect task group meeting. Comments are welcome. The work in progress document can be found in the following directory: http://www.eda.org/ibis/ibis-iss_wip/ NEW ISSUES None.
