familiar with creation of IBIS 3.2 models and is interested in the evolution
of IBIS.  Antonio Girardi of STMicroelectronics introduced himself.  He has
been developing IBIS models of memory products for about six years.  He is
currently involved with the the Futures committee.


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 no changes since the last update.  Texas Instruments
is officially renewed as a member.  We have closed off renewals for the
year, but new memberships are being solicited.  There are 30 members total.


REVIEW OF MINUTES AND ARS
Michael Mirmak reviewed the minutes of the July 15, 2005 IBIS Open Forum
teleconference.  The minutes were approved without changes.


PRESS AND WEB PAGE UPDATES
Syed Huq reported that the Green Streak logo was added to the poster page.
Updates to the FAQ page is in progress.  The events page is updated with new
contact information for DesignCon East.


MAILING LIST ADMINISTRATION
Bob Ross reported that everything is working normally.


NEW MODELS AVAILABLE, LIBRARY UPDATE
Lance Wang is planning to review the library at the end of this month.


MISCELLANY/ANNOUNCEMENTS
Bob Ross requested an addition to the agenda - an IBIS macro model committee
report.


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).

Michael Mirmak reported regarding the Interconnect Modeling for Integrated
Circuits (IMIC) specification.  This standard developed by the EIA-Japan
mentions IBIS.  Michael said that the public comment period has closed, so
no comments from the IBIS committee can be submitted until the standard is
put through further development and approval processes.


EIA/ANSI APPROVAL ACTIVITIES
Randy Wolff reported that the IBIS 3.2 re-approval process for ANSI
standardization completed the public comment period on July 25, 2005.  This
is considered the official date for ANSI approval.  This completes the
EIA/ANSI standard approval process, so the IBIS 3.2 specification is good
for another five years.  Also, Randy said that the ICM 1.1 EIA approval
process is progressing, and the ICM 1.1 specification should begin the
official public comment period soon.  Bob Ross mentioned that international
standards approval is due next year on the same five year cycle, so we will
have to find the correct IEC representative to work with on this process.


SUMMITS

- DesignCon East IBIS Summit
  DesignCon East will be held in Worcester, Massachusetts from September
  19-21, 2005.  September 19 will be the IBIS Summit.  Syed Huq sent out the
  first announcement.  The IEC has taken care of basic booth arrangements
  such as tables and chairs.  Bob Ross mentioned that Bob Haller is prepared
  to pick up the booth wherever it is shipped to and take it to the
  conference center.  We also need to arrange for an LCD projector on site
  from Cadence or SiSoft.

- Asian IBIS Summit
   Bob Ross reported that December 6, 2005 is the official date of the
   Summit. It will be held at the Crown Plaza Hotel in Shenzhen, China near
   Hong Kong.  Bob said that the first announcement has gone out.  The
   steering committee is headed by Jiang Xiang Zhong of Huawei.  Sigrity and
   Zuken have been added as sponsors, joining Huawei, Cadence, Mentor, and
   SiSoft as financial sponsors.  The deadline for presentations is set to
   be one month in advance.  Bob will be collecting all the signup
   information.

Sponsorship opportunities for DesignCon East and the Asian IBIS Summit are
still available, with sponsors receiving free mentions in the minutes,
agenda, and other announcements.


IBIS MACRO MODELING COMMITTEE
Arpad Muranyi, following up from the report at the June 14, 2005
IBIS Summit Meeting, reported that a provisional IBIS Macro Modeling
Committee is meeting weekly.  Arpad and Bob Ross requested that this
provisional group become an official task group of the IBIS Open Forum.
Arpad said that the goal of the committee is to write a standard *-AMS
library of basic SPICE building blocks for use in macro modeling.  This
idea is based on Donald Telian's macro modeling proposal, but uses the
*-AMS languages for netlisting the macro models together with the proposed
standard library building blocks.  The standard library would be written
in such a way that tools which don't have the capability of interpreting
*-AMS equations could substitute the building blocks of the standard library
with their corresponding native elements and still be able to simulate the
macro models.  This work would also pave the way for better acceptance of
AMS languages.  Bob asked if there was a committee chair.  Arpad stated that
there was no official chair, but he agreed to serve as the main contact for
reporting to the IBIS Committee.  Meetings are scheduled for Tuesdays at
noon PST. A new website exists and contains documents, minutes, and mailing
list information:

     http://www.sisoft.com/ibis-macro/

While EDA participants are encouraged to become involved, the participation
is open to the IBIS community.  Michael Mirmak will inform the GEIA of the
formation of the committee.


IBIS QUALITY COMMITTEE
Bob Ross reported that at the August 2 meeting, they worked on BUG90 that
introduces a caution flag in the parser.  The next meeting is September 6.
The committee will probably make a presentation for DesignCon East.

The link to the quality committee checklist is at:

   http://www.eda.org/pub/ibis/quality_wip/


IBIS MODEL REVIEW COMMITTEE
No update.


FUTURES AND COOKBOOK COMMITTEES
Michael Mirmak reported that there were meetings of both committees
yesterday.  Most of the meeting was BIRD95 discussion.  Lance Wang presented
some data related to BIRD95.  The cookbook is now on its fourth draft, with
a fifth draft being prepared for release next week.  This draft is posted
with new information about clamp tables for on-die terminations.  A vote
will be scheduled for approval of the cookbook at the August 26
teleconference meeting.

Recent committee material is stored at:

   http://www.ibis-information.org/futures/

Draft 5 of the cookbook will be available at the following url for review:

   http://www.eda.org/ibis/cookbook/ibis-cookbook-review-draft5.pdf


NEW ADMINISTRATIVE ISSUES
None.


BIRD99.1: AMS LANGUAGE VERSIONS
Arpad Muranyi has not received any comments or questions recently.  BIRD99.1
removed reference to "or later" with reference to the spice language.  This
BIRD revises the specification to change mention of support for a specific
AMS language to support of the latest officially approved version of the
language.  Itzik Peleg began discussion about how a model creator can know
what version of the AMS language they can use that will be supported.

A vote was called for to approve BIRD99.1 and include it in the next version
of the specification.  The vote passed with the following vote tally:

Cadence           - abstain
Cisco             - yes
Intel             - yes
Marvell           - no
Mentor            - abstain
Micron            - yes
Siemens           - abstain
Sigrity           - abstain
Teraspeed         - yes
Texas Instruments - abstain

Michael Mirmak planned to see if there were any issues with approval of the
BIRD due to the number of abstentions.


BIRD95.6: POWER INTEGRITY ANALYSIS USING IBIS
Syed Huq summarized that this BIRD adds I vs. T tables for power supply
analysis.  Bob Ross mentioned there were only editorial changes in BIRD95.6
over BIRD95.5 and no technical changes.  Itzik Peleg asked about inclusion
of the [Requiv], [Cequiv], and [Lequiv] keywords that were in BIRD95.3.
Syed said that there were existing ways of implementing these parameters
with current IBIS language such as with the [Series] keywords, so it was
removed from the BIRD to allow flexibility in modeling the power supply
impedance.  Syed said that techniques to model power supply impedance would
be described in a future revision to the Cookbook.  Bob mentioned that the
ICM specification allows for very complex descriptions of the power supply
impedance, and once linkage is defined between ICM and IBIS, this will be an
option.  Michael Mirmak mentioned that at the Futures committee discussion,
there was concern that not enough test cases had been investigated.  Ian
Dodd said that perhaps a publicly available model should be used for a case
study.  John Angulo said that progress could be made very quickly if Cisco
can do a quick analysis on the model used by Cadence.  In Cadence's study,
it showed poor modeling results with BIRD95.6.  Lance Wang said that anyone
who would like the model simply needs to email him with the request.  Lance
also stated on Cadence's behalf that Cisco’s BIRD95 contributions and
efforts need to be well recognized and highly appreciated, especially
Zhiping Yang’s technical advice during Cadence’s test period.  A call for
vote was delayed to allow for more work to be done.  Syed Huq has requested
more active participation from EDA vendors in Futures meetings for BIRD95.6.
A Futures committee discussion to go over more correlation study results
will be planned for next week.

The Cadence study presented at the last Futures committee meeting can be
found at the following link:

http://www.eda.org/pub/ibis/futures/BIRD95Tests_Aug42005_IBIS_Future.pdf


BIRD94.2: CLARIFICATIONS ON [DIFF PIN] PARAMETERS
Arpad Muranyi reported that BIRD94.2 is ready for approval vote at the next
meeting.


BIRD97.2: GATE MODULATION EFFECT
No discussion.


BIRD98: GATE MODULATION EFFECT (TABLE FORMAT)
See BIRD97.2 for discussion related to BIRD98.


IBISCHK4 BUG STATUS
Michael Mirmak reported that there are three new BUGs filed against the
parser.  BUG88 is related to compilation of the code for Linux.  The BUG is
classified as moderate, medium, and open.  Michael asked John Angulo to look
into this BUG.  BUG89 was filed by Shangli Wu of Cadence.  This BUG relates
to a complaint by the parser of the wrong illegal keyword when the parser
checks an EBD file.  This BUG is classified as moderate, medium, and open.
BUG90 was filed by Bob Haller on behalf of the IBIS Quality Committee.  This
BUG proposes to add a new category of warning type called caution.  The
first caution statement would relate to a Vmeas level being outside of the
Vinh/Vinl levels.  This BUG is classified as an enhancement, low, and open.
Michael, on a request from Bob, plans to compile a list of the open BUGs and
proposals for all the fixes.


ICMCHK1 BUG STATUS
No new BUGs have been reported.


NEW TECHNICAL ISSUES
None.


NEXT MEETING
The next IBIS Open Forum teleconference will be held August 26, 2005 from
8:00 AM to 10:00 AM US Pacific Time.  Votes are scheduled for BIRD94.2,
BIRD95.6, and approval of draft 5 of the cookbook.
