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 membership for 2005 looks to be approximately 30 members including renewals and new memberships. The actual membership at this time is 25 based on carrying over last year's list and adding Xilinx as a new member. He is formalizing invoicing details with GEIA. If a company has not received an invoice yet, they should see their invoice next week. There was no update on the treasurer's report. REVIEW OF MINUTES AND ARS Michael Mirmak reviewed the minutes of the December 10, 2004 IBIS Open Forum teleconference. The minutes of the meeting were approved without change. PRESS AND WEB PAGE UPDATES Syed Huq reported that he is in the process of updating the membership roster for 2005. He is following up with new members to get contact information, etc. Bob Ross mentioned not including the membership asterisk next to the names of new members until their payment is received by GEIA. NEW MODELS AVAILABLE, LIBRARY UPDATE Lance Wang reported no new models available. He asked new members to send him links to online IBIS model locations, and he will put them in the model library. MISCELLANY/ANNOUNCEMENTS Roy Leventhal mentioned the 2005 IEEE EMC Symposium August 8-12 in Chicago. The IEEE EMC Society has shown a remarkable increase in interest in signal integrity and power integrity simulations, and many members are familiar with IBIS and use IBIS models in simulation. More information can be found at: http://www.emc2005.org/ OPENS FOR NEW ISSUES None. MAILING LIST ADMINISTRATION Bob Ross reported one day of outage on the reflector. That has been resolved. He has also seen some of the spam filters reject some emails. INTERNATIONAL/EXTERNAL PROGRESS Michael Mirmak reported on work group relations with IEEE/DASC on VHDL-AMS and Accellera on Verilog-AMS. He is in contact with the Accellera Verilog-AMS group leader. Of note is that the VHDL-AMS working group is having its first meeting of the year at the DATE conference in Munich. He wants to make sure that one IBIS representative will attend this meeting. Also, the VHDL-AMS Standard Packages standard has been approved, so this should be noted for future IBIS activities. SUMMITS - DesignCon IBIS Summit, January 31, 2005, Santa Clara, CA DesignCon 2005 will take place January 31 - February 3, with a Summit scheduled for Monday, January 31. Syed Huq will send out a third call for papers Monday. An agenda will be sent out no later than one week before the summit (January 24). Presentation materials are needed before that date. Syed has received notice of five individual papers so far. The luncheon will be provided by DesignCon during the keynote speech. We need to make our own arrangements for refreshments, and Michael Mirmak is looking into this. Michael received notice that the IBIS booth is #940 on the display floor. John Angulo and Mentor are taking care of booth arrangements including setup and tear down. - DATE European IBIS Summit, March 11, 2005, Munich, Germany DATE 2005 will take place in Munich, with a Summit planned for Friday, March 11. Ralf Bruening of Zuken has concluded making arrangements for the room and other logistics. Bob Ross reported that the first announcement was sent out and that several presentations are already planned. - JEITA Asian IBIS Event, March 24, 2005, Tokyo, Japan Michael Mirmak reported that JEITA members are still in the planning stages. JEITA has requested some IBIS participation, however the event is closed. Sponsorship opportunities for all these Summits are still available, with sponsors receiving free mentions in the minutes, agenda, and other announcements. IBIS ANSI BALLOT STATUS Randy Wolff reported that the balloting process was closed on December 23, 2004. A final vote tally has not been received from GEIA, however unofficial vote tallies show that the ballot for reapproval of IBIS 3.2 was successful. During the process, several inconsistencies between IBIS and GEIA on primary and secondary contact names was cleared up. S2IBIS3 STATUS Ambrish Varma reported that he needs to implement new clamp subtraction algorithms. He will be looking into that and is in contact with Bob Ross. A new release will be provided eventually. The next version will be released as 1.0 (non-beta). S2IBIS3 beta executables can be downloaded from: http://www.ece.ncsu.edu/erl/ibis/s2ibis3/s2ibis3.htm Feedback on the current version is appreciated and encouraged. IBIS VERSION 4.1 PARSER STATUS Bob Ross reported no further progress. ICM SPECIFICATION AND PARSER STATUS Michael Mirmak reported that there have been offline discussions with Kelly Green regarding BUGs. No major issues have been found with the parser as it stands today. IBIS QUALITY COMMITTEE Bob Haller reported that the committee is meeting on the first Tuesday of each month. The last meeting was January 4. The next meeting will be February 8th. The discussion at the last meeting was about categorizing which checks are not in the parser and whether or not they should be warnings or cautions. IBIS MODEL REVIEW COMMITTEE No report. FUTURES AND COOKBOOK COMMITTEES Michael Mirmak reported that next Thursday is the next meeting. The final Cookbook is planned to be completed by DesignCon for discussion at the DesignCon IBIS Summit. Contact Michael Mirmak if interested in participating. Recent committee material is stored at: http://www.ibis-information.org/futures/ NEW ADMINISTRATIVE ISSUES None. BIRD92.1: MULTIPLE TERMINATOR AND SERIES ELEMENTS UNDER [MODEL] Michael Mirmak asked for discussion to be deferred until the next meeting. BIRD94: CLARIFICATIONS ON [DIFF PIN] PARAMETERS Arpad Muranyi summarized the BIRD. It attempts to fix several issues related to the [Diff Pin] keyword in the IBIS specification. These include interpretations of "NA" and error checking related to model types. The BIRD cleans up conflicting language about the usage of NA values and default settings used when data is not present. Arpad stressed that NA and 0 should not mean the same thing. Bob Ross supported some parts of BIRD94, but he wanted to proceed carefully due to the amount of changes and the possibility that some EDA vendors have relied on the existing language. BIRD95: POWER INTEGRITY ANALYSIS USING IBIS Syed Huq introduced the BIRD. This BIRD proposes a modeling scheme to integrate power integrity analysis into the IBIS specification. This includes the current switching profile of the core as well as Simultaneous Switching Noise (SSN) of the I/O stages of a buffer. Itzik Peleg of Marvell raised concern that a note needs to be added about time correlation to rising/falling waveforms in the [Series Composite Current] tables. It was also recommended to state that the load condition for each I-t table should be the same as the R_fixture value of the corresponding V-t table, otherwise the value would be assumed to be 50 ohms, as this is the default value for V-t tables per the specification. Arpad Muranyi was curious about including an I-t table not correlated to a V-t table. The consensus was that there must be a voltage table for every current table, and they are linked. Bob Ross questioned whether the data could be useful without the open, no-load condition. This will need to be investigated further. Syed concluded the discussion with a request for comments on the diagram. Several other people asked questions and raised issues, and many of the points were subsequently expressed on the IBIS reflectors. BIRD96: [MODEL SPEC] AND [RECEIVER THRESHOLDS] ORDERING Discussion was deferred until the next meeting due to time constraints. IIRD2.3: FREQUENCY DEPENDENT RLGC MATRICES The call for vote was postponed until the next meeting. IIRD8.2: DISTINCT MODEL_PINMAP AND MODEL_NODEMAP NAMES The call for vote was postponed until the next meeting. IBISCHK4 BUG STATUS Discussion was deferred until the next meeting. ICMCHK1 BUG STATUS Discussion was deferred until the next meeting. NEW TECHNICAL ISSUES None. NEXT MEETING An Open Forum teleconference has been scheduled for January 28, 2005 from 8:00 AM to 10:00 AM US Pacific Time. Votes are scheduled for IIRD2.3, IIRD8.2, and BIRD92.1. The next IBIS Summit will be held January 31, 2005. No telephone bridge is available. ============================================================================ 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.
