MEMBERSHIP UPDATE AND TREASURER'S REPORT Stephen Peters reported that Teraspeed Consulting has joined as a Voting member listed above, making a total of 31 members. Stephen and Bob Ross are still contacting several other prospective member companies. Our financial reporting from EIA usually lags actual receipt of payments, so our official reports typically show fewer members until months later. REVIEW OF MINUTES AND AR'S Stephen Peters noted that the June 28, 2002 minutes had the subject line omitted SUBJECT: June 28, 2002 EIA IBIS Open Forum Meeting Minutes Also the spelling of Atul Agarwal was corrected in the IBISCHK3 section. These changes were made in the uploaded copy. The minutes were approved with these corrections. The ARs were discussed during the meeting. MISCELLANY/ANNOUNCEMENTS None. PRESS AND WEB PAGE UPDATES Stephen Peters reported that the Syed Huq updated the IBIS upcoming events page and the roster page. Bob Ross reported that the July 8, 2002 article "Mesh Slimming Speeds Spicelink Simulation" in Electrical Engineering Times, page 44, mentions an IBIS driver addition to the Ansoft tool. NEW MODELS AVAILABLE, LIBRARY UPDATE Roy Leventhal reported no new updates since June. Stephen Peters remarked that he had visited the model web page recently and thought that the look and feel of the page was improved. Stephen thanked Roy for his upkeep of the page. OPENS FOR NEW ISSUES None. 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. Because there have not been any reports from either the JC-16 committee or the T10 SCSI Signal Modeling group in over a year, Stephen Peters announced that we will drop these items from future agendas. IBIS QUALITY COMMITTEE Bob Ross reported that the IBIS Quality committee met on July 2, 2002 and again on July 16, 2002. The committee continues working on the checklist, and expect to have it ready by the October summit meeting. Greg Edlund, reading from the quality committee minutes, noted that one topic for discussion has been the addition of a header at the top of the IBIS file that would summarize what is in the check list. Bob Ross mentioned that as a result of the IBIS parser update the parser test cases have been uploaded on the Quality Web Site. IBIS OPEN SOURCE PARSER PROPOSAL DISCUSSION No report. IBIS MODEL REVIEW COMMITTEE DISCUSSION Bob Ross reported that he is previewing a model. It may be sent back to the originator. NEW ADMINISTRATIVE ISSUES John Angulo reported that he has removed several old e-mail addresses from the reflector mail list. BIRD76 - Additional Information Related to C_comp Refinements Stephen Peters introduced BIRD76 as an editorial correction to the IBIS 4.0 draft. The purpose of this bird was to clarify the usage of the additional C_comp parameters introduced by BIRD65.2. Stephen emphasized that this BIRD does not change any of the technical content or intent of the original BIRD65.2, it only adds clarification language. Changes include changing the name of two of the C_comp subparameters: C_comp_power has been changed to C_comp_power_clamp and C_comp_gnd has been changed to C_comp_gnd_clamp. In addition, the usage rules for the added subparameters have been reworded to distinguish between the use of a subparameter and the use of its value. A paragraph was also added that clarifies what each added distributed capacitance represents (i.e. which prototype circuit element the capacitance parallels). Finally, the last paragraph under the [Rising Waveform] and [Falling Waveform] keyword usage rules was updated to refer to the new C_comp subparameters. Bob Ross had a few editorial comments. 1. Under sub-params: remove the word "and" from the list and add a missing comma 2. In the third change paragraph, change 'parameters' to 'subparameters' 4. In the second change paragraph, change references from I-V curves to I-V tables. Bob asked if there was a technical requirement that the usage of any of the C_comp* subparameters implies the existence of the corresponding I-V table. Arpad Muranyi replied that this was not the intent. After discussion, a proposed wording was excepted that clarifies this point. Finally, Bob requested that references to "simulator tool(s)" be changed to "EDA tool(s)", and this change was accepted. The motion was made and seconded to accept BIRD76 with the above revisions, with the understanding that this BIRD would become part of the draft version of IBIS 4.0. The motion passed unanimously. This BIRD will be posted as BIRD 76.1 and Bob Ross will upload it to the web page. IBIS VERSION 4.0 REVIEW AND VOTE Stephen Peters opened the discussion by noting that the draft IBIS 4.0 specification is available under the Version 4.0 Work In Process link on the IBIS web page under the file name of ver4_0wip1.txt. http://www.eda.org/pub/ibis/ver4.0_wip/ Stephen noted that he has received the following three editorial comments on the current draft: 1) Under the [Model] keyword, remove the word "and" from the sub-parameter list 2) Under the [Model Spec] keyword table description, change "spec" to "specification" 3) Under the [Test Data] keyword description, the last sentence is incomplete. Based on the original editorial update from Guy de Burgh, the sentence should conclude with the word "originated." Stephen then asked for any other editorial or technical comments on the draft specification. Bob Ross asked to remove any reference to SPICE, as this term has not been defined by the specification. After discussion the group agreed to replacing SPICE with the phrase 'circuit model'. Bob Ross also noted the following: -Change all dates for Copyright keywords from 1999 to 2002 in examples -Change [File Name] name from ver3_2.ibs to ver4.0.ibs -Under [Package Model] change in Usage Rules to ... Section 3, "GENERAL SYNTAX RULES AND GUIDELINES". - to be consistent with same phrase under [File Name] -[Model Spec] example for Vref .. needs to be aligned with the rest of the subparameters -Extra linefeed in [Receiver Thresholds] before Usage Rules: -Under [Pulldown], [Pullup], [GND Clamp], [POWER Clamp] Other Notes: Change: To limit the complexity of the IBIS Version 2.x and Version 3.x syntax checking programs, .... To: To limit the complexity of the IBIS syntax checking programs, ... -[Test Load] second example, remove the reference to the IBIS accuracy handbook section. Stephen asked for a motion to accept IBIS 4.0 with the editorial revisions noted above. It was so moved and seconded. The motion to accept IBIS 4.0 as amended passed unanimously. After the editorial updates have been done, Bob Ross will upload the final IBIS version 4.0 specification to the web site. IBIS CONNECTOR & FUTURES GROUP REPORT Stephen Peters reported that weekly meetings continue, with meetings held July 9, and again on July 18, 2002. The next meeting is scheduled for August 1, 2002. The group reviewed the ICM specification keywords and subparameters for self consistency and consistency with the conventions established by IBIS3.2. Numerous changes were made, and the latest specification will be posted to the web site under the Connector Info Link as ICM_999.txt http://www.eda.org/pub/ibis/connector/ The only remaining issue is including text that describes keyword positioning rules. The intent is to resolve this issue over the next week or so, then at the August 1, 2002 meeting vote to release the specification to the IBIS Open Forum for review and comment. BIRD74.1 - EMI Parameters Guy de Burgh had no update, and discussion was differed to the next meeting. BIRD75.2 - Multi-Lingual Modeling IBIS Modeling Support BIRD77 - Differential Subparameter Additions Bob Ross stated that BIRD75.2 and BIRD77 were both issued together as an update to BIRD75.1. The major change prompting a separate BIRD77 is the proposed additions of true differential model types: Input_diff, I/O_diff, 3-state_diff, and Output_diff and two differential timing test loads: Rref_diff, Cref_diff. These required documentation as subparameters within the existing [Model] and [Model Spec] keywords. Furthermore, the differential timing test load can be used as an extension to existing IBIS without any of the Multi-lingual extension of BIRD75.2. On BIRD77, Bob noted several editorial comments were received at the IBIS connector/futures group meeting, and he will incorporate them into a revised BIRD77.1. These comments include clarifying the connection of the added timing test loads and adding an example of timing test load usage. Stephen Peters also noted that the added model types are only applicable if the [External Model] keyword is present, and that BIRD75 will have to be considered before BIRD77. Bob also covered a number of editorial improvements and changes in BIRD75.2 based on better tuning the capabilities to the needs. Bob mentioned that the name of the "cell_port" subparameter were changed to "signal_pin". For timing locations, the BIRD has reverted back to the current locations used in IBIS version 3.2. Some of the prototype port names have also been changed. Bob proposed that we formally call for a vote at the next meeting on both BIRDs. IBISCHK3 & BUG TRACKING STATUS Bob Ross reported that the source code for ibischk3.2.9 has been distributed. The executables have been generated and uploaded. BUG57 through BUG67 except BUG59 and BUG62 were fixed. Bob thanked Matthew Flora for distributing the source code and creating the Windows executable. Thanks also go to Guy de Burgh and Lynne Green for the Unix and Linux executables. The new executables are found at: http://www.eda.org/pub/ibis/ibischk3/ Finally, Bob Ross reported that Michael Mirmak of Intel has submitted a revised test case for BUG68. This test case is shorter than the previous file that demonstrated the problem. NEXT MEETING: The next teleconference meeting will be on August 9, 2002 from 8:00 AM to 10:00 AM Pacific Daylight Time. Votes are scheduled on BIRD75.2 and BIRD77.1. ============================================================================ 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, Innoveda 1369 Del Norte Rd.
