INTERNATIONAL/EXTERNAL PROGRESS - IEC 62014-3 (ICEM) Integrated Circuit Electromagnetic Model Proposal (formerly, IEC 93/67/NP IBIS and EMC Simulation) - Stephen Peters needs to review the some comments on the Cookbook and Report document. - JEDEC JC-16 - Modeling and Testing - No report. - T10, Project 1414-DT - SCSI Signal Modeling (a Technical Committee of the National Committee for Information Technology (NCITS)) - No Report. DAC 2002 IBIS SUMMIT MEETING PLANNING REVIEW Stephen Peters called for comments on the IBIS Summit Meeting held on June 13, 2002 in New Orleans, Louisiana. Stephen felt that there was some very worthwhile discussion on the open source golden parser issues as well as finishing off IBIS 4.0 in light of the multi-lingual modeling proposal. Arpad Muranyi felt that this summit has a better balance between the technical and business items. Arpad also asked if there was going to be a follow up BIRD to Luca Giacotto's presentation on modeling IBIS model output impedance and C_comp. Stephen replied that he felt that the proposal was solid enough to be put into a formal BIRD process, and would work with Luca on producing one. FUTURE IBIS SUMMIT MEETINGS As was reported at the June Summit meeting the planned joint meeting between EIA and JEDEC groups, scheduled for September in Vancouver, British Columbia was canceled. The JEDEC group will still be meeting, but it is unknown if any EIA affiliated group will be joining them. While the consensus was to not hold an official IBIS summit meeting in Vancover, British Columbia, Lynne Green has indicated she will attend selected JEDEC meetings as an official IBIS representative and report back to the Open Forum. Stephen Peters mentioned that we are still planning on holding an IBIS summit meeting on October 17 in Boxborough, Massachusetts. This meeting, hosted on site by North East System Associates (NESA), will coincide with the PCB East Conference. IBIS QUALITY COMMITTEE Stephen Peters reported that a meeting was held June 18, 2002. The next meeting is scheduled for July 2. Reading from the minutes of that meeting, work continues on developing the IBIS checklist. IBIS OPEN SOURCE PARSER PROPOSAL DISCUSSION Stephen Peters recapped the discussion at the June IBIS Summit. In brief, Stephen argued that there was a greater quality advantage in developing an open source base for the current spice-to-ibis program rather than pursuing open source development of the Golden Parser. Also, while we can pursue a dual license strategy of open source licensing along with a commercial type license, the IBIS Open Forum must verify that enough companies will still be willing to fund development of the new parser. Further discussion was postponed due to a lack of quality committee representatives. IBIS MODEL REVIEW COMMITTEE DISCUSSION Stephen Peters reported that a model from Philips was sent out for review. MAJORDOMO UPDATE John Angulo has nothing new to report. NEW ADMINISTRATIVE ISSUES None. IBIS VERSION 4.0/BIRD75 DISCUSSION Stephen Peters reported that the latest draft of the IBIS 4.0 specification (ver4_0wip1.txt) has been uploaded to the IBIS web site. It is under the Version 4.0 Work In Process link http://www.eda.org/pub/ibis/ver4.0_wip/ This version has been updated with the editorial corrections as discussed during the March 28 and April 19 IBIS teleconferences. The changes include: -- Change 'Description' field of [Manufacture] keyword per minutes of the 04/19/2002 teleconference -- Clarified usage of [Alternate Package Model] keyword per minutes of the 04/19/2002 teleconference -- [Temperature Range], added reference to NOTES ON DATA DERIVATION METHOD per 03/28/02 teleconference minutes -- Changed "100 voltage point" limit to "100 row" limit in the [Pullup] and [Pulldown] keyword text per the 03/28/02 teleconference minutes. -- Changed [R Series], etc. keyword description per 03/28/02 teleconference minutes. Changed [Series Current] keyword "100 point" reference per 03/28/02 teleconference minutes. -- Added clarification text to description of [Test Data] keyword per the 4/19/02 teleconference minutes. -- Changed "100 voltage points" to "100 rows" in the [Series MOSFET] keyword -- Changed "100 voltage points" to "100 rows" in the [GND Pulse Table] and [POWER Pulse Table] keywords. Also corrected first sentence of usage rules per 04/19/02 teleconference minutes. Stephen summerized the specific changes one by one. No issues were noted. Stephen then opened a discussion on the issue of the new C_comp distribution subparameters added by BIRD65. During the editorial review process, it was discovered that there is no explanation in the current draft text of were the distributed capacitances represented by the new C_comp parameters are to be applied in the prototype simulation model. It was also felt that the usage rules for these subparameters could be clarified. In response, Arpad Muranyi posted a proposed new BIRD. This BIRD would add a new paragraph that explains where the distributed capacitances are to be applied in the prototype simulation model. In addition, the names of two of the original subparameters, "C_comp_power" and "C_comp_gnd", were changed to "C_comp_power_clamp" and "C_comp_gnd_clamp" respectively to better reflect their purpose. Some minor wording changes to the current draft text were also proposed. During the following discussion John Angulo noted that the [Rising Waveform] and [Falling Waveform] keyword descriptions should be edited to refer to the appropriate C_comp or C_comp* subparameters. A few wording changes were also introduced in the first paragraph to better distinguish between the inclusion of a subparameter and the use of its value. Stephen agreed to update Arpad's proposal and formally issue a BIRD76. While no technical content was changed from the current draft 4.0 specification, it was felt that the text changes were extensive enough to warrant formal documentation by a BIRD. A vote on BIRD76 will be conducted before the vote on IBIS 4.0. The final vote on IBIS 4.0 is tentatively scheduled for July 19, 2002. Stephen urged those present to review the document and forward any comments to the IBIS reflector two weeks before the meeting. IBIS CONNECTOR & FUTURES GROUP REPORT Stephen Peters reported that weekly meetings continue, with meetings held June 5, and again on June 20 and June 25, 2002. The next meeting will be on July 9. The group is still working on last minute editorial corrections and clarifications to the specification, including a technical issue on the use of the swathing parameters for connectors. The latest version of the draft specification (ICM_998.txt) will be made available on the IBIS web page under the connector Info link at the following URL. http://www.eda.org/pub/ibis/connector/ BIRD74.1 - EMI Parameters Guy de Burgh has issued an updated BIRD74.1, incorporating some of the comments made previously. Guy also indicated that he wanted to remove the [Model EMI] keyword from the current BIRD, as this keyword was better located in the connector spec. Other than that Guy is comfortable with the current proposal. Guy indicated that he will issue an updated BIRD74.2 before the next meeting. BIRD75.1 - Multi-Lingual Modeling IBIS Modeling Support Arpad Muranyi summarized the comments he has forwarded to BIRD author Bob Ross. In brief, Arpad questioned the need for the [Node List] keyword -- it is optional, as all it does is declare node names. The response was that this keyword should actually be required, and declaring the nodes serves much the same purpose as declaring variables in a programming language. Arpad also asked about combining the [External Model] and [External Circuit] keywords. Mentor's response was that these keywords appear in different places, thus they have different scoping requirements. In addition, these keywords have different types of arguments. Arpad indicated that he would like to see more discussion on these issues and on BIRD75.1 as a whole. IBISCHK3 & BUG TRACKING STATUS Stephen Peters reported that Atul Agarwal is currently traveling. Atul will have the latest IBISCHK3 update, IBISCHK3.2.9 which includes a fix for BUG67, available by July 4, 2002 at the latest. NEXT MEETING: The next teleconference meeting will be on July 19, 2002 from 8:00 AM to 10:00 AM Pacific Daylight Time. Votes are scheduled on BIRD76 and IBIS 4.0 specification. ============================================================================ NOTES IBIS CHAIR: Stephen Peters (503) 264-4108, Fax: (503) 264-1831 stephen.peters@intel.com Senior Hardware Engineer, Intel Corporation M/S JF4-215 2111 NE 25th Ave. Hillsboro, OR 97124-5961 VICE CHAIR: Lynne Green (425) 788-0412, Fax (425) 451-1871 lgreen@cadence.com Senior Modeling Engineer, Cadence Design Systems 20 120th Ave NE, Suite 103, Bellevue, WA 98005-3016 SECRETARY: Guy de Burgh (805) 988-8250, Fax: (805) 988-8259 gdeburgh@innoveda.com Senior Manager, Mentor Graphics 1369 Del Norte Rd.
