--------------------------------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 since it is the beginning of the year, the
participants list in the minutes has been cleaned up. Renewal notices have
been sent out to participants. Bob Ross asked about Intel's parser payment.
Michael was not sure if it was paid before the end of the year.
REVIEW OF MINUTES AND ARS
Michael Mirmak reviewed the minutes of the December 16, 2005 IBIS Open Forum
teleconference. The minutes were approved without changes.
PRESS AND WEB PAGE UPDATES
Michael Mirmak reported that the GEIA server is online now, and updates to
the eda.org server have been made. Bob Ross suggested we look at moving the
site completely to the GEIA server.
MAILING LIST ADMINISTRATION
Bob Ross reported that everything is running normally.
NEW MODELS AVAILABLE, LIBRARY UPDATE
Michael Mirmak reported for Lance Wang that one link has been updated for
ICS on the models page.
MISCELLANY/ANNOUNCEMENTS
None.
OPENS FOR NEW ISSUES
None.
INTERNATIONAL/EXTERNAL PROGRESS
There continue to be two pending standards under consideration by the
International Electrotechnical Commission (IEC) under the technical
committee TC47. Each of these standards have links back to IBIS. We are
the appropriate committee to review and comment on these documents. The
documents are available for technical review from Bob Ross. More
information can be found at the following url:
http://www.iec.ch
The two standards are:
IEC62404 I/O Interface Model for Integrated Circuits (IMIC) as 47A/704/CD
(committee draft). This is a competing standard with IBIS and is an
enhancement to spice languages.
Models of Integrated Circuits for EMI Behavioral Simulation 47A/719/NP
(new work proposal). This is a follow on to ICEM (ICEM is 62014-3).
EIA/ANSI APPROVAL ACTIVITIES
Randy Wolff reported that he had received no updates from GEIA on the status
of the ICM 1.1 specification ANSI approval. Michael Mirmak reported that he
had received an email from Chris Denham at GEIA stating that the close date
for ANSI review is June 9, 2006. A brief discussion ensued on turning the
Cookbook version 4 into a GEIA engineering bulletin. Michael confirmed that
we can post a non-official version of the cookbook on our website and have
an official version for purchase through the GEIA store. Further updates to
the Cookbook may need to be finished before any voting occurs on the
cookbook issue.
SUMMITS
- Asian IBIS Summit
The Summit was held December 6, 2005 at the Crown Plaza Hotel in Shenzhen,
China near Hong Kong. Michael Mirmak thanked all the sponsors and
organizers of the event. He mentioned that he is still receiving
questions and comments about the event from participants. Michael and
Bob Ross are still working on a few financial issues related to the
summit.
- DesignCon
The DesignCon Summit will be held Thursday February 9, 2006 in Santa
Clara, California. Fred Balistreri is handling the registration. Bob
Ross reported that the second announcement was sent out. Four
presentations have been scheduled so far. Ian Dodd will be attending
DesignCon, so he will take care of setup of the IBIS booth. Cisco will be
a primary sponsor of the event. Bob recommended pre-registering for the
DesignCon event soon.
- DATE
The summit will be Friday, March 10, 2006 in Munich, Germany. Michael
Mirmak reported that Ralf Breuning sent out the second announcement
recently.
Sponsorship opportunities for DesignCon and DATE are still available, with
sponsors receiving free mentions in the minutes, agenda, and other
announcements.
IBIS QUALITY COMMITTEE
Bob Ross reported that the next meeting will be January 10. Mike Labonte is
serving as a temporary chair during the transition of Bob Haller leaving as
the chair.
The link to the quality committee checklist is at:
http://www.ibis-information.org/quality_wip/
IBIS MODEL REVIEW COMMITTEE
No new models received.
FUTURES AND COOKBOOK COMMITTEES
Michael Mirmak reported that there were discussions in the Futures meeting
on user defined measurements and on the lengths of model names and file
names. The question arose about international participation in the
meetings. It may make sense to hold special meetings at a different time
to accommodate members in European and Asian time zones. Lynne Green had
mentioned in the meeting several comments related to the Cookbook. There
were specific comments related to the load used in the [Ramp] keyword. Bob
Ross suggested that we make changes to the Cookbook before looking at
turning the Cookbook into an engineering bulletin. Michael mentioned that
he would like Lynne to create a document that will list the changes made to
the Cookbook. Stephen Peters mentioned that the Touchstone 1.2
specification was never officially approved by the IBIS committee. Version
1.1 was officially approved. He requested looking into officially approving
the 1.2 specification. Michael will find a contact at Agilent to discuss
this with, and he will get this person into contact with Stephen Peters
and Sam Chitwood. Sam would like to see the IBIS committee take on the
standardization of the Touchstone format so that it is not controlled by any
specific vendor.

MACROMODELING LIBRARY COMMITTEE
Arpad Muranyi reported that there was a meeting this week. Presentation
topics were discussed for the upcoming summit. Arpad is still working on
the VHDL flavor of the library.
Committee material can be found at the following url:
http://www.ibis-information.org/macromodel_wip/
NEW ADMINISTRATIVE ISSUES
None.
BIRD97.2: GATE MODULATION EFFECT
Arpad Muranyi reported that he received an email from Antonio Girardi in mid
December. Antonio was planning to run more experiments. Antonio and Arpad
are trying to determine how complex the BIRD needs to be. Michael Mirmak
mentioned holding a special Futures meeting to discuss this BIRD further.
BIRD98: GATE MODULATION EFFECT (TABLE FORMAT)
See BIRD97.2 for discussion related to BIRD98.
BIRD100.1: ALLOW PURE ANALOG *-AMS MODELS
Arpad Muranyi reported that this version of the BIRD was posted in December.
He has not received any comments on the updated BIRD. John Angulo asked
about adding more examples to the BIRD. Arpad said that he updated the
figures, but he did not add any examples yet. Arpad plans to make final
changes next week so that the BIRD can be put up for vote at the next IBIS
Open Forum meeting.
BIRD101: SECTION 6B, FIGURE 12 EXAMPLE NOTE
Bob Ross said that the purpose of the BIRD is to add one note above
Figure 12 documenting that some of the material in Figure 12 is not part of
the current specification. There are some pad to pin connections in the
figure in anticipation of ICM linkage, however this linkage is not part of
the specification currently.
There was a call for vote on approval of the BIRD text for inclusion in the
next version of the IBIS specification. The vote passed with the following
vote tally:
Intel - yes
Mentor - yes
Micron - yes
Sigrity - yes
Teraspeed - yes
IBISCHK4 BUG STATUS
Randy Wolff mentioned that he is working on a BUG report related to
non-monotonic warnings in [Submodel] I-V curves. Specifically, separation
of On-die Termination (ODT) characteristics from normal [POWER Clamp] and
[GND Clamp] characteristics leads to non-monotonic regions in the ODT I-V
curves. The recombination of the curves results in a monotonic curve,
however the parser does not combine [Submodel] curves with the [Model]
curves to check for overall monotonicity. Michael Mirmak mentioned that
there are 8 BUGS filed currently that will need to be dealt with moving
forward.
ICMCHK1 BUG STATUS
Michael Mirmak reported that a BUG has been filed that calls for making a
repair to BUG1. Running the parser in very verbose mode, text blocks in
the disclaimer over 1024 characters caused problems. This parser version
also reports incorrect use of a text string field after [End ICM Section],
as changed in ICM 1.1. If the original BUG1 demonstration file is edited to
comply with ICM 1.1 rules, the hang issue returns: the parser provides many
lines of output but never returns to a command prompt. Michael suggested
that BUG2 be filed as moderate, medium, and open.
Michael discussed how to make changes to the ICMCHK1 parser, as we can not
rely on Kelly Green for making changes. Bob Ross suggested that we plan to
make changes within the committee's resources, and ask Kelly about
consulting on our changes.
NEW TECHNICAL ISSUES
None.
NEXT MEETING
The next IBIS Open Forum teleconference will be held January 27, 2006 from
8:00 AM to 10:00 AM US Pacific Time. A vote is scheduled for BIRD100. The
next IBIS Summit will be held February 9, 2006 at DesignCon. No telephone
bridge is available.
