MINUTES-----------------------------------
INTRODUCTIONS AND MEETING QUORUM
New participant Lance Wang of Cadence Design Systems introduced himself.
While he has attended previous summit meetings, this meeting was his
first
Open Forum.
CALL FOR PATENTS
Michael Mirmak called for any patents or pending patents related to the
IBIS Version 4.0, 4.1, or ICM 1.0 specifications. No patents were
declared.
MEMBERSHIP UPDATE AND TREASURER'S REPORT
Michael Mirmak mentioned that Open Forum membership remained at 28
organizations through the end of 2003. He met personally with
GEIA representatives at their headquarters in early January and
confirmed that the 2004 membership invoices had been completed
and mailed. The Open Forum is to expect the 2003 annual financial
statement in mid February.
Michael also reported that the 2004 membership drive has already
resulted in several renewal commitments from current members and one new
member.
Bob Ross noted that Samtec has joined as a new member in 2004 and has
a membership invoice in processing. Syed Huq reported that
the IBIS roster listing has been updated and a Samtec logo is being
added to the virtual poster.
REVIEW OF MINUTES AND ARS
The December 5, 2003 meeting minutes were approved with no changes.
Michael Mirmak noted that the GEIA archives copies of the IBIS Open
Forum minutes after approval by the GEIA counsel.
MISCELLANY/ANNOUNCEMENTS
No additional announcements were made.
PRESS AND WEB PAGE UPDATES
In response to a question, Syed Huq noted that the EIGROUP web site
updates have not yet been posted, as the EIGROUP web administrator
has recently changed. Bob Ross suggested that the new EIGROUP
administrator be reminded that the IBIS Open Forum expects a one-day
response on web site update requests. Bob also mentioned that Arpad
Muranyi's latest IBIS training foils have been posted to the EDA site.
Arpad Muranyi inquired about the format of the BIRD reports on the
IBIS eda.org website. At present, none of the files has a .txt
extension identifying as a text file to internet browsers. As a
result, the files can cause a variety of inconvenient barriers to
easy viewing. Ian Dodd noted that certain Mentor products use
numerical file extension associations and often attempt to open
BIRD reports viewed online. Michael Mirmak accepted the AR to add
.txt extensions to the existing BIRD reports and to confirm with Arpad
that the fix resolves the problem.
NEW MODELS AVAILABLE, LIBRARY UPDATE
No new models received.
OPENS FOR NEW ISSUES
No new issues.
MAILING LIST ADMINISTRATION
John Angulo reported that the ibis-request, ibis-info, ibis-bug and
icm-bug
mailing list reflectors are now handled entirely under majordomo.
Passwords
and other administrative details have been distributed appropriately.
John also noted that Randy Harr of eda.org reported that the eda.org
servers crashed on or about December 22. The archive used to restore
the IBIS directories showed only a few differences due to recent
reflector
messages and HTML updates.
In response to a question, Bob Ross observed that the reflectors have
between 400 and 450 subscribers.
INTERNATIONAL/EXTERNAL PROGRESS
- JEDEC Activity Report
Lynne Green reported that she will present to the JEDEX conference on
IBIS during the week of April 15, 2004.
- FSA Modeling Committee
Lynne Green reported that she will present a talk on IBIS quality to
the Fabless Semiconductor Association in San Jose during the week of
April 15, 2004.
The Fabless Semiconductor Association can be found at:
- Other Activities
No update
DESIGNCON 2004 SUMMIT PLANNING
Lynne Green reported that a draft agenda for the DesignCon Summit has
been prepared and a third call for papers has been distributed. A
fourth call will be issued during the week of January 12.
Michael Mirmak reported that, thanks to the efforts of Syed Huq, Cisco
has
kindly agreed to provide refreshments for the summit. Michael thanked
Syed and Cisco for their contribution.
Bob Ross observed that Guy de Burgh may wish to send out another
reminder
to member organizations to provide logos for the display booth. In
addition, Lynne Green reminded attendees to register with her for the
summit if they had not already done so. Syed Huq confirmed that he will
be making paper copies of presentations for distribution at the summit.
Syed requests that all presentation materials be sent to him no later
than one week before the summit. Paper copies will be printed two
slides
per double-sided page.
EUROPEAN DATE SUMMIT PLANNING
Bob Ross reported that a third DATE announcement has been distributed
and
six speakers are tentatively scheduled to present, on topics including
ICEM and applications of multi-lingual technologies.
Cadence Design Systems, Mentor Graphics and Zuken
are collaborating to sponsor the IBIS Summit which will take place on
Friday, February 20, 2004 in Paris. The summit will run from 9 AM to 2
PM
Paris local time. Potential speakers and participants are welcome to
contact Ralf Bruening of Zuken or Bob for further details. Thanks again
to
Ralf and to Eckhard Lenski of Siemens for arranging the summit.
OTHER SUMMITS
Bob Ross noted that the annual DAC meeting, at which IBIS officer
elections
have taken place in the past, will be held in San Diego in June 2004.
Additionally, a DesignCon conference will be held in Manchester, New
Hampshire on the US East Coast in April 2004. Bob suggested that a
summit
might be held during this DesignCon in a similar fashion to the summit
held
in October 2003. For such a summit, the logistics associated with a
booth
may be more profitably applied toward a teleconference bridge. East
Coast
organizations such as SiSoft, NESA or Cadence may be interested in
hosting
the meeting. Michael accepted the AR to investigate this further and to
contact the appropriate organizations.
Bob also noted that a DesignCon for Europe was being planned for
October,
most likely in Munich.
IBIS VERSION 4.0 PARSER FUNDING AND STATUS
Michael Mirmak reported that the invoice for the 4.0.1 parser has been
received and filed for payment with the GEIA. The 4.0.1 parser
executables were posted and distributed in December, 2003. IBIS 4.0
parser work is therefore considered closed until BUG reports, if any,
are
filed for the 4.0.1 version.
IBIS QUALITY COMMITTEE
Bob Ross reported that meetings continue every two weeks, with the next
scheduled for January 13. A meeting was announced for December 30, but
was
quickly adjourned due to lack of attendance. Edits continue on the
comprehensive quality guidelines and checklist document. No formal
title
has yet been assigned to the document. A report on the committee's
progress will be delivered at the DesignCon summit.
IBIS MODEL REVIEW COMMITTEE
Lynne Green reported that no new models have been received by the
committee since the last meeting. She noted that Lance Wang is the
new model reviewer from Cadence Design Systems. Lynne accepted the
AR to ensure that the website reflects this.
S2IBIS3
Bob Ross reports no changes since the last meeting.
S2IBIS3 beta executables can be downloaded from:
http://www.ece.ncsu.edu/erl/ibis/s2ibis3/s2ibis3.htm
Feedback on the current beta version is appreciated and encouraged.
ICM SPECIFICATION AND PARSER STATUS
Michael Mirmak again raised the issue of a specification change process
for ICM, similar to the IBIS BIRD process. The BIRD (Buffer Issue
Resolution Document) acronym, however, clearly cannot apply. The
members
present suggested a variety of names, including IIRD (ICM Issue
Resolution
Document), ICM-RD (ICM Resolution Document) and even ICHABOD.
Lynne Green suggested, due to time constraints, that all suggestions be
sent to Michael Mirmak for consideration. The new name will be
announced by Michael at the next meeting.
NEW ADMINISTRATIVE ISSUES
No new issues.
BIRD85.3: SLEW TIME CLARIFICATIONS
John Angulo introduced BIRD85.3, an update to BIRD85. The revised text
clearly states that the Rload subparameter is ignored if [Ramp] is
used under an [External Model]. No additional comments or questions
were raised.
Michael Mirmak called for a formal vote. The BIRD was approved
unanimously and will be included in the draft text of version 4.1 of
the IBIS specification.
BIRD86.1: CLARIFICATION OF SUBMODEL MODE
Lynne Green introduced BIRD86.1, an update to BIRD86. The revised text
adds a paragraph to explain the available Submodel modes, but now simply
brings the specification into conformance with current parser behavior.
No additional comments or questions were raised.
Michael Mirmak called for a formal vote. The BIRD was approved
unanimously and will be included in the draft text of version 4.1
of the IBIS specification.
IBIS VERSION 4.1 FOURTH READING
Michael Mirmak announced the fourth official "reading" of the IBIS 4.1
specification, and called for comments.
Bob Ross volunteered to add the two approved BIRDs to the 4.1 draft and
post the updated text. At present, a 4.1D edition is posted.
Michael raised the issue of an approval vote. According to Open Forum
bylaws, documents requiring approval votes must be publicly available
for
at least two weeks, to allow for adequate review. Lynne Green suggested
that at least one meeting be held to discuss a stable version of the
draft
specification before any vote. Michael noted that a vote could take
place at the IBIS Summit in February; Bob confirmed that at least one
previous version of the specification was approved through a summit
vote. Ian Dodd voiced the opinion that such face-to-face meetings may
not be the best venue for deciding such issues, as discussions of
relatively minor issues might prevent the vote from ever taking place.
Bob and Arpad Muranyi suggested that a stable review draft, including
the
latest BIRDs, be posted within one week of this meeting. This would
allow
two weeks of review before the January 30 Open Forum. If issues arose
at
that meeting which would prevent an approval vote, further discussion
could
take place at the summit. This plan was adopted without objection.
Draft copies of version 4.1 are available in a variety of formats at:
http://www.eda.org/pub/ibis/ver4.1_wip/
BUG80
John Angulo summarized the current state of BUG80. The BUG applies a
more
strict interpretation of keyword hierarchies than is made explicit in
the
specification. In addition, the BUG error message could be clarified.
Arpad noted that he was working on a clarification of [Model Selector]
and
series element keywords, as the [Series Pin Mapping] definition does not
clearly state its relationship with [Model Selector]. Bob agreed that
some sort of BIRD would be required to clarify many of the top-level
keywords' scopes, including perhaps adding a hierarchy tree explicitly
to
the specification, as Michael has suggested in the past. The BUG report
will remain open until one or more BIRDs are issued to clarify the
affected
keyword scopes.
NEXT MEETING
The next Open Forum teleconference has been scheduled for January 30,
2004 from 8:00 AM to 10:00 AM US Pacific Standard Time. A vote
regarding
the approval of IBIS 4.1 is scheduled.
The next IBIS Summit will take place at DesignCon 2004 on February 2,
2004
at the Santa Clara Convention Center, California.
