She responded that these capabilities are not currently in the system but will be available soon. Bob noted that the system would be useful for recording votes. KAVI members’ login is at: http://workspace.techamerica.org/apps/org/workgroup/ibis-members SUMMIT STATUS -SPIE IBIS Summit The 15th IEEE Workshop on Signal Propagation on Interconnects will be held in Naples, Italy, May 8-11, 2011. The IBIS Summit is scheduled for May 11. Antonio Girardi of Micron (formerly Numonyx) is local to Naples and was able to get a meeting room from 1:00pm to 6:00pm. The cost is minimal, but no sponsorship has been secured at this time. The first announcement has gone out. There are a few presentations planned so far. The meeting is mentioned on the SPI webpage. -DAC IBIS Summit The Design Automation Conference (DAC) is June 6-9, 2011 in San Diego, CA. The IBIS Summit will be held June 7. A conference room has been secured at the Omni Hotel. This meeting will include the annual election of officers. Contact the board if you are interested in running for an office. The first call for papers should go out mid April. Sponsorship opportunities are available. Bob Ross noted that we need to start securing money and sponsorships for a summit in Taiwan. 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 there were no meetings the last two weeks. The group is still working on a test load proposal. They are presuming that IBIS-ISS will be used to describe the test load. The group is meeting weekly on Tuesdays at 8AM PST. 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 is finishing up a BIRD draft with crosstalk for AMI modeling. He is hoping for a vote on it next week to advance it to the Open Forum. They are also working on fixing the table syntax for AMI. His goal is to complete the AMI fixes by DAC. 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 discussing the IBIS-ISS draft. They are working through about 100 comments, mostly editorial and clarifications. The focus of the task group is to complete reviewing and fixing the IBIS-ISS draft. Arpad Muranyi asked if there is a target date to complete the document update, such as by DAC. Several other proposals are contingent on IBIS-ISS completion. Michael responded that he is setting a goal of having the list complete by DAC, but he does not guarantee a completed draft document at that time. Task group material can be found at: http://www.eda.org/ibis/interconnect_wip/ IBIS EDITORIAL UPDATE Michael Mirmak reported that there is a mailing list for the editorial group. Join if you are interested in participating. The group has had a couple of meetings. The purpose of the project is to re-format IBIS 5.0 without making any technical changes to have a framework for updating future versions of IBIS. Bob Ross noted there are other questions about whether sections should be renumbered to conform to TechAmerica document standards, and whether this would then need to become a version 5.1. Arpad Muranyi noted that it will probably need to become IBIS 5.1 so that the two documents are distinguishable. This also affects BIRDs since they will need to refer to page numbers of a specific document. BIRDs currently pending for IBIS 5.1 may need to be reformatted to be part of IBIS 5.2. New IBIS 5.0 documentation can be reviewed at: http://www.eda.org/ibis/reformat_wip/ NEW ADMINISTRATIVE ISSUES None. BIRD116: ADD IBIS-ISS TO [EXTERNAL MODEL] AND [EXTERNAL CIRCUIT] AS A SUPPORTED LANGUAGE Arpad Muranyi reported that in the last ATM teleconference, a question was raised on whether we would discuss all the various BIRDs he has submitted. Arpad has given presentations on the BIRDs and is awaiting feedback. He encouraged people to review the BIRDs and submit comments. Walter Katz discussed how BIRD122 came from BIRD119, the Opal analog AMI modeling BIRD. After significant discussion on BIRD122 in IBIS ATM, he re- wrote it and submitted it to the ATM as BIRD122.1. It integrates IBIS-ISS, package models, AMI and external models. This new BIRD he thinks is a response to Arpad’s BIRDs and must be discussed. Radek Biernacki asked if BIRD122 is a competing BIRD to Arpad’s BIRDs. Arpad said that depending on the content of the latest update to BIRD122, it might be a potential replacement. Walter would like discussion on BIRD122 tabled until the ATM committee has discussed it. Arpad does not know yet if this new BIRD will compete with any of his BIRDs. BIRD117.3: PARAMETERIZE A_TO_D AND D_TO_A CONVERTERS Arpad Muranyi reported that a change to BIRD117 and BIRD118 allows an AMI parameter reference to have a default value so if the AMI file is not available or if the name is not found, then a hard coded literal in the IBIS file could be used. Bob Ross stated that he doesn’t like defaults, because he would rather an error come up in simulation than the simulation complete but not give a useful result. Further discussion was tabled. BIRD118.2: ANALOG PARAMETER ASSIGNMENTS See BIRD117.3 for related discussion. BIRD120.1: IBIS-AMI FLOW CORRECTION Arpad Muranyi reported that he submitted the revision, and it was a small change so multiple GetWave calls do not have to use the same block size. This came from discussion on the ATM reflector. Walter Katz moved to schedule a vote on the BIRD in the next Open Forum teleconference. There were no objections. BIRD121: IBIS-AMI NEW RESERVED PARAMETERS FOR DATA MANAGEMENT Walter Katz noted that he would like the ATM task group to discuss the BIRD and make recommendations to support it or not before scheduling a vote in this meeting. BIRD122: IBIS-AMI NEW RESERVED PARAMETERS FOR ANALOG MODELING Walter Katz reported that he has made significant changes to BIRD122 that require further discussion in the IBIS ATM call. BIRD123.1: IBIS-AMI NEW RESERVED PARAMETERS FOR JITTER/NOISE Walter Katz noted that the BIRD was changed to add Rx_Noise_Pad. He requested that the BIRD be discussed by the ATM task group before discussing further in the Open Forum. Michael Mirmak pointed out that the changes in BIRD123.1 are not obvious in the .txt document, so a PDF may need to be posted. BIRD124: IBIS-AMI NEW RESERVED PARAMETERS FOR DEPENDENCY TABLES Discussion was tabled. BIRD125: MAKE IBIS-ISS AVAILABLE FOR IBIS PACKAGE MODELING Arpad Muranyi noted that there have been no comments since Walter Katz’s comments in the last Summit. Changes may be necessary to the BIRD. Bob Ross noted that he needed to review the BIRD further and make comments. BIRD127: IBIS-AMI TYPOGRAPHICAL CORRECTIONS Arpad Muranyi noted that he has not received any recent comments. Bob Ross added that he expected some minor changes to the BIRD based on discussions in the ATM task group. BIRD128: ALLOW AMI_PARAMETERS_OUT TO PASS AMI_PARAMETERS_IN DATA ON CALLS TO AMI_GETWAVE Walter Katz reported that there have been no changes to BIRD128. There have been a lot of discussions on backchannel modeling, with Gennum, Sigrity, and SiSoft agreeing on the mechanism in the BIRD. Radek Biernacki noted that it was requested at the last Open Forum call to discuss this BIRD further in the ATM committee. Arpad Muranyi added that he needs to add this to the ATM call agenda. BIRD129: ADD “POLARITY” ARGUMENT TO D_TO_A CONVERTERS Arpad Muranyi introduced the BIRD. It is a simple BIRD designed to allow the usage of inverted D_to_A converters when an [External Model] (or [External Circuit]) contains a differential model so that the model would not have to implement the inverter for the stimulus. TSCHK2 BUG STATUS No new BUGs to report. This item will be removed from future agendas until any BUGs are submitted. IBISCHK5 BUG STATUS BUG127 was introduced by Bob Ross. He found an instance where some illegal text within an AMI file causes a fatal error crashing the parser. The BUG was classified as Severe severity, High priority and Open status. Bob also summarized BUG128. This BUG documents the case where a Reserved_Parameters and Model_Specific section was repeated in the AMI file and the parser did not flag an error. The BUG was classified as Annoying severity, Medium priority and Open status. IBISCHK5 UPDATE STATUS Michael Mirmak reported that IBISCHK5 version 5.0.6 has been officially released. Bob Ross noted that Release 5.0.5 was never released due to finding BUGs in it. IBIS-ISS SPECIFICATION DRAFT Michael Mirmak reported that current comments are being reviewed in the Interconnect task group. The draft is open for further comments. The draft 1 revision can be reviewed at: http://www.eda.org/pub/ibis/ibis-iss_wip/IBIS_ISS_review_draft_1.pdf NEW TECHNICAL ISSUES None. NEXT MEETING The next IBIS Open Forum teleconference will be held April 22, 2011 from 8:00 to 10:00 AM US Pacific Standard Time. BIRD120.1 is scheduled for a vote at this meeting. The next IBIS Summit will be held at SPI in Naples, Italy on May 11, 2011. No teleconference bridge will be provided. The following Open Forum teleconference will be held May 13, 2011. ======================================================================== NOTES IBIS CHAIR: Michael Mirmak (916) 356-4261, Fax (916) 377-3788 michael.mirmak@intel.com Platform Applications Engineer, Intel Corporation 1900 Prairie City Rd., FM5-239 Folsom, CA 95630 VICE CHAIR: Lance Wang (978) 633-3388 lwang@iometh.com President/CEO, IO Methodology, Inc.
