REVIEW OF MINUTES AND AR'S
The minutes from the May 31, 2002 teleconference were approved without
change.
The minutes from the June 13, 2002 IBIS Summit Meeting were approved without
change.
The ARs were discussed during the meeting.
MISCELLANY/ANNOUNCEMENTS
None.
PRESS AND WEB PAGE UPDATES
None.
NEW MODELS AVAILABLE, LIBRARY UPDATE
Roy Leventhal produced June 1 and 9, 2002 updates to the Models page. Many

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.
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 Atual Agarwal is currently traveling. Atual
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.
