Bob Ross thanked Guy de Burgh for conducting the last meeting and handling general IBIS business. MEMBERSHIP UPDATE AND TREASURER'S REPORT Cecilia Fleming reported receiving the purchase order from Ansoft Corporation for EIA IBIS Open Forum membership. So Ansoft Corporation is now listed as a voting member. Guy de Burgh reported that he has generated an updated IBIS roster, but is still checking on some comments. Bob Ross commented that a few of the members that are on his list have been deleted this year since they have not paid. Bob will work with Cecilia off-line regarding some membership payments. REVIEW OF MINUTES AND AR'S The June 30, 2000 IBIS Minutes were approved. The AR's will be discussed during the meeting. MISCELLANY/ANNOUNCEMENTS Bob Ross had two course announcements: Raj Raghuram will be teaching a weekend course at San Jose State University on "Electrical Requirements of Microelectronic Packaging" starting September 2, 2000 and will cover IBIS if time permits. For further information contact Prof. Guna Selvaduray at SJSU: PH: (408) 924-3874 FAX:(408) 924-4057 email: gunas@email.sjsu.edu Arpad Muranyi will teach a two-day short course as part of the "Circuit Simulation and Signal Integrity in Microelectronic Circuits and Systems" as part of the 3-day short course sponsored by the University of Arizona and conducted in Phoenix, Arizona. Arpad will teach "Introduction to IBIS Models" and "IBIS Modeling Hands-on Experience". This course will be conducted in September 11-12, 2000. PRESS AND WEB PAGE UPDATES No reports other than routine web page updates. NEW MODELS AVAILABLE, LIBRARY UPDATE Mike LaBonte has provided an Update to the IBIS Model Library in the official IBIS Home page Models link. Mike will be adding some more models. He commented on the amount of work necessary to check out the links and also on the fact that links may change (and become busted) very quickly. Also, Mike is investigating the possibility of third party web sites that would support automatically locating models using their search engines. Mike will send a notice to the reflector for corrections and for information on more links. OPENS FOR NEW ISSUES None. INTERNATIONAL/EXTERNAL PROGRESS - IEC 62014-1 (IBIS Version 3.2) - Bob Ross may still need the document to help draft some header information. - pr EIAJ ED-5302 Standard for I/O Interface Model for Integrated Circuits (IMIC) - No report. - IEC PWI 93-1 Models of Integrated Circuits for EMI Behavioral Simulation (formerly designated as IEC 93/67/NP IBIS and EMC Simulation) - Ian Dodd asked if there is a Web Site. Bob Ross responded that he is waiting for some updated information that he can upload or distribute. The official information is contained in various European IBIS Summit presentations. The latest presentations are uploaded in March 2000. - JEDEC JC-16 - No Report. PCB EAST 2000 IBIS SUMMIT MEETING PLANNING Bob Ross discussed the pending IBIS Summit Meeting scheduled on Thursday, September 14, 2000 in Worcester, Massachusetts and held along with the PCB East Conference 2000. The IBIS meeting will be at the Crowne Plaza hotel, a few blocks from the PCB East Conference. So far, Cadence and NESA are co-sponsors. Bob still needs to get in touch with Kathy Breda and get other sponsors. (Guy de Burgh had sent out a sponsorship request earlier on the IBIS reflector.) Bob indicated that some preliminary information will be sent out at the end of July, about six weeks before the meeting. The expected agenda should include Connector Model Specification, IBIS futures and IBIS accuracy and experiences. Later, the following presentation is expected: Roy Leventhal, 3com, - "IBIS and SI at 3com" (Presented by Mike LaBonte, Cadence) DESIGNCON 2001 IBIS SUMMIT MEETING PLANNING Bob Ross discussed the planning done to date on the IBIS Summit Meeting held with DesignCon 2001 in San Jose, California. DesignCon 2001 is scheduled from January 29, 2001 to February 1, 2001. The IBIS Summit Meeting is currently scheduled on Monday, January 29, 2001. This was discussed at the last meeting. Bob commented in response to one issue that we are again planning to hold the meeting in one of the larger rooms. As before, we are planning to be an Associate Sponsor of DesignCon 2001. This year, we need to confirm this since we will be mentioned in the literature. One difference is that the literature will give signup information. We need to decide on this. Bob will ask National Semiconductor if they will do this again. [Added note, National will do the signup.] Otherwise, Guy de Burgh will be listed for Summit Meeting signup. Bob will also ask if National is interested again in being a co-sponsor and supplying lunch. Bob discussed having a passive booth this year. In the past we have had electrical demonstrations. However, the individuals involved may not be available this year. Guy de Burgh stated that Innoveda would be able to supply the backdrop again, and Jon Powell has velcro backed logos of member companies. Bob mentioned that he has EIA literature to hand out. So we should have some material. As before the booth provides a neutral meeting place for IBIS folks to meet without disturbing presentations at vendor booths. We agreed to go forward with these plans. IBIS MODEL REVIEW COMMITTEE DISCUSSION Matthew Flora reported that no new models have been received. We discussed some of the model review aspects. This was also discussed at the last meeting. Several individuals submitted documents on the IBIS reflector on validating models. Bob Ross mentioned that he also spends about one to four hours reviewing models and providing comments. Also the reviewers are intended to be from EDA vendors since part of the process is to test the models in various EDA tools. Mike LaBonte suggested that it might be helpful to have more test waveforms supplied for correlation. He currently does comparisons with the table waveforms that are inside the IBIS model. CONNECTOR PROPOSAL REVIEW (CONTINUED) Bob Ross commented that the Connector Working Group is continuing to meet regularly. The last meeting was on July 18, 2000. The subject was to continue on clarify the Swath approach. The goal is to agree within the Working Group and revise the document accordingly. Then it will release the document to the IBIS Open Forum for full committee review. Bob needs to document a possible algorithm for expanding the Swath into a larger Swath or full connector model. Gus Panella had supplied several 2 by X connector model examples as the basis of the discussion. IBIS FUTURES (IBIS-X, API, BIRDxx) Mike LaBonte reported that the last teleconference was on July 11, 2000. Al Davis had a number of files containing proposals, and the Working Group is sifting through this data. The committee has reached some general agreement regarding some circuit elements. John Angulo is responsible for generating a template for the proposed format. The next meeting is scheduled for Tuesday, July 25, 2000. Michael Cohen indicated that he wanted to become involved. Stephen Nolan's proposal regarding an HTML version of IBIS will be discussed. Michael Cohen asked if there has been any consideration regarding an HDL version. Mike stated that so far they are waiting for someone (Michael) to look into it. Bob Ross commented on IBIS 4.X plans in response to a question raised at the last meeting. Bob stated that IBIS 4.X would be an upgrade to IBIS 3.2 that would include: BIRD62.6 for receiver thresholds Other pending BIRDs that are approved (probably the C_comp BIRD65) Possibly some agreement regarding BIRD61. An addition for SSO per proposals made by Dr. Bernhard Unger at various IBIS Summit Meetings. The next meeting is scheduled for Tuesday, July 25, 2000. Michael Cohen indicated that he wanted to become involved. IBISCHK3 BUG TRACKING - BUG34 - No Error Reported for Missing V/I Tables in Output Buffers Matthew Flora had issued revised text to simplify the Error messages. Bob Ross regarded the revisions as acceptable. The group approved the action modify ibischk3 per BUG34. - BUG41 - Issue Warning Instead of Error for Common Differential Pin Bob Ross indicated that the changes of BUG41 will be implemented per the actions of the last meeting. - BUG42 - Warning Message for Outputs with Thresholds Needed Per the discussion at the previous meeting, Matthew Flora still intends to propose revised wording for the Warning message. We reviewed some of the previous discussion including the extent to which the test could be conducted. AR - Matthew Flora propose revised wording for the BUG42 Warning message. - BUG43 - Error for Zero or Negative dV/dt Ramp Data Needed Bob Ross mentioned that BUG43 was discussed, but not classified at the last meeting. After some discussion, we decided that this should be an Moderate, Medium, Open. Also, after some discussion following from the last meeting, we decided that this message should be a Warning message (versus and Error message). Bob wanted the most simple test and did not want it to consider combinations of keywords (e.g., whether or not [Driver Schedule] was invoked, whether or not [Rising Waveform] and [Falling Waveform] tables were used, etc.). For some cases, the problem may not be important in some (but not all) EDA simulators. In other cases, the bad data will cause the simulation to fail in most simulators. Therefore, this is an important Warning to review. - BUG44 - Warning for Parasitic Resistance Set Too High at 1000 Ohms Bob Ross reviewed the discussion of the previous Meeting. BUG44 had been classified, but the new resistance value had not been set. After some more discussion, the group decided on 50 ohms. - BUG45 - GND* and POWER* Nets Generate Errors in EBD Files Michael Cohen introduced BUG45 which had been recently submitted. An Error message is issued with net names starting with GND and POWER in EBD files. IBIS allows net names to have more characters. Since the ibischk3 parser incorrectly issues Error messages for correct files, this was classified as Moderate, High, Open. We plan to submit BUG45 to be fixed. Bob Ross commented that Mike LaBonte had sent out on the IBIS reflector some comments on ibischk3. Included was a comment that 80 character lines that pass in Unix may fail when translated into DOS format - creating a lot of Error messages. Mike plans to issue a BUG report on this problem. Bob commented that he will find our the status of the Bug fixes from Atul Agarwal. Michael Cohen indicated that he would like to have an updated parser soon. BIRD61.1 - ENHANCED CHARACTERIZATION OF RECEIVERS Not Discussed. BIRD64.1 - PACKAGE MODE SELECTOR Michael Cohen mentioned that he wants this discussed at the next meeting. BIRD65 - C_comp REFINEMENTS Arpad Muranyi reported that he will issue an updated BIRD65.1. Bob Ross wants to discuss this at the next meeting. BIRD66 - [Model Spec] Vref ADDITION Not discussed. NEXT MEETING: The next teleconference meeting will be on Friday, August 11, 2000 from 8:00 AM to 10:00 AM. ============================================================================== NOTES IBIS CHAIR: Bob Ross (503) 685-0732, Fax (503) 685-4897 bob_ross@mentor.com Modeling Engineer, Mentor Graphics 8005 S.W.
