--------------------------------MINUTES-----------------------------------
INTRODUCTIONS AND MEETING QUORUM
No new participants.
CALL FOR PATENTS
Michael Mirmak called for any patents or pending patents related to the IBIS
Version 3.2, 4.0, 4.1, or ICM 1.1 specifications. No patents were declared.
MEMBERSHIP UPDATE AND TREASURER'S REPORT
Michael Mirmak reported that an initial treasurer's report was received for
2005 and the beginning of this year. Most financial issues have been
resolved. Many renewals have been received, but there are many more to
come in.
REVIEW OF MINUTES AND ARS
Michael Mirmak reviewed the minutes of the February 9, 2006 DesignCon IBIS
Summit and the February 17, 2006 IBIS Open Forum teleconference. The
minutes were approved without changes.
PRESS AND WEB PAGE UPDATES
Michael Mirmak reported that there are updates to the roster being made with
new member joins. Bob Ross is helping to correct or purge obsolete
information from the roster. Syed Huq reported that he added a new entry
from SimLab in Germany to the roster.
MAILING LIST ADMINISTRATION
Bob Ross reported that everything is running normally. Bob noted that some
subscribers are only on one of the two mailing lists, and this does cause
some erroneous bounces. Bob suggested that we might start sending
announcements and minutes to only the ibis and not ibis-users list. Or we
might merge the two lists. Michael Mirmak suggested this be discussed in
the administrative meeting.
NEW MODELS AVAILABLE, LIBRARY UPDATE
Michael Mirmak reported for Lance Wang that he updated site lists of models
links. No new companies have been added. Michael mentioned that Bob Ross
was looking into posting a separate link to ICM models. Roy Leventhal
thought this would be a good idea.
MISCELLANY/ANNOUNCEMENTS
None.
OPENS FOR NEW ISSUES
None.
INTERNATIONAL/EXTERNAL PROGRESS
Bob Ross had no new report. Michael Mirmak mentioned that he is still
investigating handling of IBIS issues with the TC93 committee in IEC.
EIA/ANSI APPROVAL ACTIVITIES
Randy Wolff reported that he received word from GEIA that the ICM 1.1
specification gained ANSI approval on January 18, 2006. Michael Mirmak sent
a message to the IBIS reflector detailing this. Michael also mentioned that
GEIA issued a press release, and the EETimes picked up the story.
Official copies of the new standard, ANSI/GEIA STD-0001-2006, are available
through GEIA (http://www.geia.org).
Randy also stated that there is officially a project opened with GEIA to
prepare for IBIS 4.2 standardization. So, once IBIS 4.2 is released by the
Open Forum committee, it is ready to begin the GEIA standardization process.
SUMMITS
- DATE
The DATE summit was held Friday, March 10, 2006 in Munich, Germany.
No update on the event was available during the teleconference. Bob Ross
said that there were 22 signups before the meeting. Bob has many of the
presentations uploaded to the IBIS website. Bob noted that four people
from Japan attended. Also, Arpad Muranyi was going to be meeting with
some people to discuss the gate modulation BIRD.
- Summits in Asia
Michael Mirmak reported that he sent a note to JEITA and others regarding
the possibility of events in Japan in the March/April timeframe. The note
said that we would not be able to organize an event this early in the
year, but suggested that a summit in October would be better. Bob Ross
mentioned that another Asian IBIS Summit in China might also be scheduled
in the same timeframe for economical US travel to all Asian activities.
IBIS QUALITY COMMITTEE
Mike Labonte reported that they did not make quorum for the last meeting, so
there is no new committee progress to report. He was pleased to see some
models with IBIS Quality headers in them recently. Bob Ross mentioned that
there is another meeting next Tuesday.
The link to the quality committee checklist is at:
http://www.ibis-information.org/quality_wip/
IBIS MODEL REVIEW COMMITTEE
Michael Mirmak reported for Lynne Green that the committee concluded review
on a recent model. The committee is open for receiving new models to
review.
FUTURES AND COOKBOOK COMMITTEES
Michael Mirmak reported that both committees have been meeting every
Thursday. The committee is waiting for feedback from Lynne Green on V-t
table descriptions in the Cookbook. There were two separate discussions on
the IBIS 4.2 draft. The committee also had a preliminary review of an ICM
to IBIS linking method. A draft BIRD was put forth, and there was good
discussion and comments.
Recent committee material is stored at:
http://www.ibis-information.org/futures/
The Cookbook version 4 is stored at:
http://www.ibis-information.org/ibis/cookbook/cookbook-v4.pdf
MACROMODELING LIBRARY COMMITTEE
Mike Labonte reported that there are some new Perl based tools being written
for the library as well as a lot of work on improving what has been
completed so far. There has been good participation from the EDA companies,
and this is key to the library being successful.
Committee material can be found at the following url:
http://www.ibis-information.org/macromodel_wip/
NEW ISSUES
None.
IBIS 4.2 DRAFT
Michael Mirmak mentioned that Bob Ross and Arpad Muranyi have been working
on the draft IBIS 4.2 document, and he officially introduced it for review
by the Open Forum. He said that three readings will be held to give time
for review and updating. This meeting is the first reading. Bob Ross said
that for editorial cleanup, the multilingual section syntax on figures needs
work. Michael mentioned that some editorial and minor grammatical issues
were discussed in the Futures meeting. Bigger issues involve matters of
referencing of I-V tables. The text mentions voltage rails, but this may
need to be changed to mention specific voltage nodes. Bob said that this
would be a good cleanup, but it probably wouldn't change how many simulators
use the models. John Angulo agreed with this assessment. Michael asked if
we have posted an updated draft revision that lists the changes made to the
document. Bob said that this has been handled so far. Michael said that
any comments can be sent to the reflectors, any members of the IBIS board,
Bob Ross or Arpad Muranyi, or bring them up in the next meeting. Michael
also mentioned that there are minor edits in the package and EBD sections
that need to have specific units defined for inductances and capacitances.
BIRD97.2: GATE MODULATION EFFECT
No update. Arpad Muranyi was planning to discuss the BIRD with Katja
Koller and Antonio Girardi at the DATE Summit.
BIRD98: GATE MODULATION EFFECT (TABLE FORMAT)
See BIRD97.2 for discussion related to BIRD98.
IBISCHK4 BUG STATUS
Randy Wolff introduced BUG93, "Single-ended Threshold Warnings for
Differential Models." Randy found that in models that combine differential
[Receiver Thresholds] parameters, the [Diff Pin] keyword to reference two
pins of the component to be differential, and multiple [Model]s referenced
through the [Model Selector] keyword, the parser gives a false error. The
IBISCHK4 parser is confused by the [Model Selector] and thinks that the
[Model]s should contain single ended [Receiver Thresholds] parameters.
Errors and warnings are issued related to this.
Michael Mirmak asked if the committee had addressed this issue before. Bob
Ross said that the committee began defining requirements of differential
buffers in the [Model Selector], but did not address this specifically.
This appears to be a testing flaw with the [Receiver Thresholds] keyword.
Randy stated that it would be nice to include both single ended and
differential parameters under Receiver Thresholds. Mike Labonte agreed with
this. Randy mentioned potentially introducing a BIRD to address this.
Michael asked about classification. It was classified as Severe, Medium,
and Open. Some discussion ensued on which BUGs will be addressed in the
IBIS 4.2 parser. John Angulo has looked at this briefly, and some BUG fixes
should be very simple to implement.
ICMCHK1 BUG STATUS
Michael Mirmak mentioned that no new BUGs have been filed.
NEW TECHNICAL ISSUES
Roy Leventhal gave an overview of his new book, "Semiconductor Modeling: For
Simulating Signal, Power, and ElectroMagnetic Integrity." Lynee Green is a
co-author. Arpad Muranyi included a presentation that is on the CDROM. The
book includes chapters on key concepts of IBIS, simulating with IBIS models,
where to find models, common errors in models, and future capabilities of
IBIS. It is intended to be an engineering book, not a college textbook. It
also cites a lot of references for further study and is in general an
overview of all the different issues involved in EDA software. More

Bob Ross also mentioned another book from Springer being published on EMI.
The book is entitled "Electromagnetic Compatibility of Integrated Circuits:
Techniques for Low Emission and Susceptibility." Bob contributed a piece on
IBIS for the book. More information can be found at:
