CALL FOR PATENTS Michael Mirmak called for any patents or pending patents related to the IBIS Version 3.2, 4.0, 4.1, or ICM 1.0 specifications. No patents were declared. MEMBERSHIP UPDATE AND TREASURER'S REPORT Michael Mirmak reported that we have 29 paid members. Two members have been removed from the members list for non-payment of dues by the middle of the year. Lynne Green of Green Streak Programs is a new member. Two other companies have invoices in the works. REVIEW OF MINUTES AND ARS Michael Mirmak reviewed the minutes of the June 24, 2005 IBIS Open Forum teleconference and the June 14, 2005 DAC IBIS Summit minutes. The minutes of both meetings were approved without changes. PRESS AND WEB PAGE UPDATES Syed Huq reported that the events page was updated for DesignCon East. The roster page was also updated for Green Streak Programs and Texas Instruments. MAILING LIST ADMINISTRATION Bob Ross reported that everything is working normally. He is seeing a lot of email bounces lately due to SPAM filters having high SPAM detection settings to the point that they filter out legitimate IBIS reflector messages. NEW MODELS AVAILABLE, LIBRARY UPDATE No update. MISCELLANY/ANNOUNCEMENTS None. OPENS FOR NEW ISSUES None. INTERNATIONAL/EXTERNAL PROGRESS Bob Ross mentioned that there continue to be two pending standards under consideration by the International Electrotechnical Commission (IEC) under the technical committee TC47. Each of these standards have links back to IBIS. We are the appropriate committee to review and comment on these documents. The documents are available for technical review from Bob. More information can be found at the following url: http://www.iec.ch The two standards are: IEC62404 I/O Interface Model for Integrated Circuits (IMIC) as 47A/704/CD (committee draft). This is a competing standard with IBIS and is an enhancement to spice languages. Models of Integrated Circuits for EMI Behavioral Simulation 47A/719/NP (new work proposal). This is a follow on to ICEM (ICEM is 62014-3). EIA/ANSI APPROVAL ACTIVITIES Randy Wolff reported that ANSI approval of the IBIS 3.2 standard reballoting is still underway. The standard entered the public review stage on June 3, 2005. This process takes approximately 45 days, so it is expected to be completed before the next Open Forum teleconference. Also, it was mentioned that the ICM specification will begin the balloting process once approved by the Open Forum committee. ICM SPECIFICATION AND PARSER STATUS Michael Mirmak reported that no new comments have been received within the last two calls for comments. Michael asked for any final comments before calling for a vote. A vote was called for to approve the ICM 1.1 specification and release it to start the EIA/ANSI balloting process. The vote passed with the following vote tally: Cisco - yes Green Streak Programs - yes Intel - yes Mentor - yes Micron - yes Teraspeed - yes Michael will review the document, and Randy Wolff will send the document to GEIA to start the EIA/ANSI approval process. Michael is also having the ICM parser licensing agreement reviewed by GEIA legal. Once this process is complete, the parser's availability can be announced and orders can be processed. SUMMITS - DesignCon East IBIS Summit DesignCon East will be held in Worcester, Massachusetts from September 19-21, 2005. September 19 will be the IBIS Summit. IBIS will be an associate sponsor. Michael Mirmak is proceeding with the final contract details. Cadence/SiSoft are co-sponsoring the event. Bob Ross talked with Bob Haller of SiSoft, and SiSoft is willing to be the onsite sponsor of the meeting. Bob Haller can pickup the booth from the Mentor Graphics site and setup the booth at the conference. Ian Dodd of Mentor is arranging for transfer of the booth to Massachusetts. Intel is picking up the cost of the teleconference bridge. Bob Ross requested sending out the first announcement next week. Syed Huq took the AR to send out the announcement. - Asian IBIS Summit Bob Ross reported that December 6, 2005 is the official date of the Summit. It will be held at the Crown Plaza Hotel in Shenzhen, China near Hong Kong. Lance Wang is currently in Shenzhen meeting with a local steering committee organized by Jiang Xiang Zhong of Huawei Technologies. A first announcement is planned in the near future to give adequate lead time for travel arrangements and agenda preparation. So far, Huawei, Cadence, Mentor, and SiSoft are financial co-sponsors of the Summit, but several more companies are expected to join. Sponsorship opportunities for DesignCon East and the Asian IBIS Summit are still available, with sponsors receiving free mentions in the minutes, agenda, and other announcements. IBIS QUALITY COMMITTEE Bob Ross mentioned at the July 12, 2005 meeting that the committee discussed issuing a BUG report to introduce a new "Caution" message. The Bug report would propose a new test to check if Vmeas is between the Vinh and Vinl values. There are some legal exceptions, but in most cases this would indicate a data entry error. The Caution checking for extended data checking would would be optionally activated by a parser flag. The next meeting is scheduled for August 2, 2005. The link to the quality committee checklist is at: http://www.eda.org/pub/ibis/quality_wip/ IBIS MODEL REVIEW COMMITTEE Lynne Green reported no new models to review. FUTURES AND COOKBOOK COMMITTEES Michael Mirmak reported that there were meetings of both committees yesterday. There were discussions of BIRD94 and BIRD95 related issues including BIRD97 and BIRD98. Also, release of the cookbook was discussed. Recent committee material is stored at: http://www.ibis-information.org/futures/ The final version of the cookbook for review is stored at: http://www.eda.org/ibis/cookbook/ibis-cookbook-review-draft1.pdf Michael asked if we should put out a note of call for comments on the reflector before issuing the final version. Bob Ross mentioned that he has filed comments publicly that will be addressed, and an official version will be posted two weeks before the next IBIS Open Forum teleconference. Lynne Green requested that a discussion be allowed for at the next meeting due to the size of the document to allow for further review. A call for vote to release the 1.0 document will take place at the following meeting. NEW ADMINISTRATIVE ISSUES None. BIRD99: AMS LANGUAGE VERSIONS Arpad Muranyi sent an updated version out to a limited audience for comment. This version takes out mentioning Berkeley SPICE and only mentions the Verilog and VHDL-AMS languages. The BIRD states that the latest version of the AMS languages should be supported. Bob Ross commented that he would like to clear up the language to state support of the most recently officially released version of the language. Ian Dodd expressed his view that a specific version of AMS should be supported to give a baseline of support common to all EDA tools. Arpad Muranyi mentioned that he wanted to see more comments issued on the reflector to give more visibility of this issue to the wider IBIS community. Arpad will distribute BIRD99.1. A call for vote will be scheduled for the next meeting. BIRD95.5: POWER INTEGRITY ANALYSIS USING IBIS Syed Huq reported that the last discussion ensued at DAC. No other comments have been received at this point. Michael Mirmak mentioned that in the Futures meeting, it was discussed that a call for vote should be made if no feedback is received to address concerns raised at the DAC meeting. A counter proposal has not been received, so it was decided to schedule a call for vote at the next meeting. Bob Ross wanted to make a few editorial changes to the BIRD and issue a revised BIRD within the next week. A revised BIRD95.6 is planned to be voted on at the next meeting. BIRD94.1: CLARIFICATIONS ON [DIFF PIN] PARAMETERS Arpad Muranyi reported that there was some discussion at the Futures meeting that concluded that there was no dual meaning to the Vdiff parameter. Lynne Green requested a minor editorial change to the BIRD. Arpad has made a few editorial changes to the BIRD as well and will post a revised BIRD. The revised BIRD94.2 will be discussed at the next meeting and a call for vote is planned for the following meeting. BIRD97.2: GATE MODULATION EFFECT Arpad Muranyi reported that he has asked for some feedback from Katja Koller about scaling coefficients related to different scaling requirements for linear versus saturation regions of transistor operation. Arpad also copied Antonio Girardi as well for feedback. More discussion will ensue once more direction is received from Katja and Antonio. Ian Dodd wondered if this BIRD was necessary due to the ability to handle gate modulation effects in the AMS languages. Arpad said that this BIRD is at a minimum allowing more accuracy in legacy IBIS until AMS languages are absolutely required. BIRD98: GATE MODULATION EFFECT (TABLE FORMAT) See BIRD97.2 for discussion related to BIRD98. IBISCHK4 BUG STATUS Michael Mirmak reported that the currently posted Linux code does not work on all systems due to the library referenced in the code not being available on all systems. This BUG has not been officially filed. Bob Ross requested that the BUG be officially filed and responded to. ICMCHK1 BUG STATUS No new BUGs have been reported. NEW TECHNICAL ISSUES Michael Mirmak reported that two new BIRDs are currently being worked on. One is related to linking of IBIS to ICM. NEXT MEETING The next IBIS Open Forum teleconference will be held August 5, 2005 from 8:00 AM to 10:00 AM US Pacific Time. Votes are scheduled for BIRD99.1 and BIRD95.6. ============================================================================ NOTES IBIS CHAIR: Michael Mirmak (916) 356-4261, Fax: (916) 377-1046 michael.mirmak@intel.com Senior Analog Engineer, Intel Corporation FM6-45 1900 Prairie City Rd.
