MEMBERSHIP UPDATE AND TREASURER'S REPORT
Michael Mirmak mentioned that Open Forum membership holds steady at 28
organizations. An updated GEIA financial report for November has been
received, and shows no change in overall revenue or expenses since the
October report.
Michael also reported that the 2004 membership drive has already
resulted
in several renewal commitments from current members and one new member.
Bob Ross suggested that invoicing be conducted as soon as possible to
give
members and prospective members maximum flexibility in budgeting their
dues.

modeling technologies, where ICM and IBIS were extensively discussed.
A recording of the seminar can be found at:
http://www.connectorwizard.com/communication/webinar/home.asp
NEW MODELS AVAILABLE, LIBRARY UPDATE
No new models received.
OPENS FOR NEW ISSUES
No new issues.
MAILING LIST ADMINISTRATION
Bob Ross noted that the transition of the IBIS reflectors to majordomo
is
complete. Reflectors for ibis-bug@eda.org and icm-bug@eda.org have been
established (see below). Recovery from the recent mailing list and
EDA.org
site outage is complete, though some mail messages received during the
outage have been lost.
INTERNATIONAL/EXTERNAL PROGRESS
- JEDEC Activity Report
No update
- FSA Modeling Committee
Lynne Green reported that the Fabless Semiconductor Association has
begun
a Model Quality initiative within their Modeling Committee and has
solicited participation by the IBIS Open Forum's IBIS Quality
Committee.

No update
DESIGNCON 2004 SUMMIT PLANNING
Bob Ross reported that he had spoken with Brock Silvey of IEC, the
organizers of DesignCon. The keynote speech of the conference will take
place at noon on February 2, the day of the IBIS Summit. Lunch will be
provided from 12 to 12:30 PM that day, with the speech to begin at 12:30
PM
and to last 30 minutes. Bob confirmed that lunch is provided to
registered
participants at the keynote, and suggested that the Open Forum direct
Summit
attendees to register for the keynote luncheon. Those registering for
DesignCon before December 19 receive free admission; prices increase to
$75
after December 19. An announcement regarding lunch was suggested for
the
IBIS reflectors, to be sent out as soon as possible. Michael Mirmak and
Lynne Green will discuss the appropriate text of the announcement after
the
meeting. Lynne commented that perhaps reserved tables might be made
available for IBIS, though Bob noted that this may not be feasible with
the
number of DesignCon participants.
Bob observed that Syed Huq was researching refreshment options and would
provide an update soon. If hotel refreshments were not available or
could
not be procured for the Summit, Bob suggested pricing local refreshment
service. Michael will report on this at the next meeting.
Michael also noted that Panasonic had provided an electronic version of
their logo, which will be displayed at the IBIS booth. No other logos
have
been received in response to the Open Forum request.
EUROPEAN DATE SUMMIT PLANNING
Bob Ross reported that Cadence Design Systems, Mentor Graphics and Zuken
are collaborating to sponsor the IBIS Summit at DATE. A call for papers
has already been provided to the IBIS reflectors. Bob noted that the
summit
will run from 9 AM to 2 PM Paris local time. Six presentations have
already
been scheduled. Speakers and participants are welcome to contact Ralf
or
Bob for further details. The Summit will take place on Friday, February
20,
2004 in Paris.
IBIS VERSION 4.0 PARSER FUNDING AND STATUS
Michael Mirmak reported that a beta release of the IBISCHK4 parser
has been received and distributed to parser code licensees.
Bob Ross noted that all BUG report issues and new 4.0 specification
features appear to have been closed. Without objection, the
beta code was approved as the final release of the IBISCHK4
parser. The code must be edited a final time to eliminate any
mention of "beta" in the output or source, and to change the
version to 4.0.1. Michael will contact the parser developer
to execute these changes and distribute the final release.
Michael noted that the remaining funds due to the parser developer, Apt
Software Avenues Pvt. Ltd., for IBISCHK4 total to US$17,635. This
amount
has been budgeted by the IBIS Open Forum and the GEIA for 2003 parser
development. Michael called for a vote on whether to disburse the funds
to the developer. The vote passed unanimously. Michael will arrange
for
an invoice to be provided by Apt to the GEIA.
IBIS QUALITY COMMITTEE
Bob Ross reported that meetings continue every two weeks. Document edits
are proceeding.
IBIS MODEL REVIEW COMMITTEE
Lynne Green reported that no new models have been received by the
committee
since the last meeting.
S2IBIS3
Ambrish Varma reported that he has completed a beta 0.2 version of
S2IBIS3
and has posted it publicly. An announcement was distributed to the
IBIS and SI-LIST reflectors.
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 reported that the 1.0 parser code and executables have
been posted to the IBIS web site on EDA.org. Announcements regarding
the release were sent to the IBIS and SI-LIST reflectors. A new
electronic mail address, icm-bug@eda.org, has been established to
process BUG reports related to the ICM parser.
Michael raised the issue of a specification change process for ICM.
Bob Ross noted that several names have been proposed for ICM change
documents, as the "BIRD" acronym used for IBIS may not apply. Michael
suggested that participants interested in proposing a name for the
ICM change process send their proposals to the IBIS Open Forum board.
A suitable name will be selected at the January 9, 2004 meeting.
NEW ADMINISTRATIVE ISSUES
No new issues.
BIRD83.2: SERIES ELEMENT CLARIFICATIONS
Michael Mirmak summarized BIRD83.2, an update to BIRD83. Michael noted
that several typographical errors in the BIRD text have been corrected.
Further, a recommendation is made in the text that, should the BIRD be
approved, a BUG should be filed to ensure that the parser properly
checks the relationship between [Series Switch Groups] and the
function_table_groups column under [Series Pin Mapping].
Michael called for a vote, stating at Lynne's request that the BIRD text
is to be included in IBIS 4.1. BIRD83.2 was approved unanimously.
BIRD84.1: DRIVER SCHEDULE CLARIFICATIONS
Arpad Muranyi summarized the changes made in BIRD84.1. The ordering
of the new text has been altered and the meaning of "events" relative
to the EDA tool's internal stimulus pattern has been clarified.
John Angulo raised some concern regarding c_comp and whether the text
changes properly address how c_comp is handled by EDA tools. At
present,
c_comp is only meaningful within the top-level model of a [Driver
Schedule]
structure. Once this aspect of the specification was clarified, John
withdrew his objection.
Michael called for a vote. BIRD84.1 was approved unanimously.
It will be included in the next release of the IBIS specification (4.1).
BIRD85.2: SLEW TIME CLARIFICATIONS
John Angulo introduced BIRD85.2, an update to BIRD85. The revisions now
include a more precise definition of the use of R_load.
Arpad Muranyi observed that the treatment of [Ramp] in the 3.2 and 4.0
specifications was quite specific -- "The R_load subparameter is
required
if a non-standard load is used." The current version of the BIRD does
not address the fact that R_load is required, but instead states that
R_load is optional. The text therefore conflicts with the [Model]
definition of R_load. As this effect was not intended, Arpad suggested
that the BIRD be rewritten.
The current BIRD text was withdrawn from consideration by John. A
BIRD85.3
version, addressing the issues above, will be distributed for discussion
at
the next Open Forum meeting. Arpad and John will meet outside of the
Open
Forum to resolve all remaining issues with the text.
BIRD86: CLARIFICATION OF SUBMODEL MODE
Lynne Green introduced BIRD86, regarding modes of [Submodel] operation.
The current text of the [Submodel] definition permits [Submodel] modes
of "Driving," "Non-Driving," and "All." However, the specification does
not clearly state if "All" refers to both Driving and Non-Driving modes
of operation. Additionally, the parser does not check for inconsistency
between the model type (for example, Input) and the [Submodel] mode.
The BIRD is intended for inclusion in IBIS 4.1
Bob Ross expressed some disagreement with the BIRD as written, as
[Submodel] has traditionally been more loosely interpreted by
EDA tools than the BIRD text would allow.
The current BIRD text was withdrawn from consideration by Lynne. She
and
Bob will work separately to resolve the remaining issues. A BIRD86.1
version will be distributed for discussion at the next Open Forum
meeting.
IBIS VERSION 4.1 THIRD READING
Michael Mirmak announced the third official "reading" of the IBIS 4.1
specification, and called for comments.
Bob Ross and Michael discussed how the new multi-lingual extensions
were to be included in the 4.1 specification. Bob Ross noted that
a separate chapter, 6b, now includes the extensions information.
Michael
suggested that these should be more closely integrated with [Model]
chapter 6, as the information under [Model] is modified by the
extensions.
Bob proposed that this be deferred until a rewrite of the specification
planned for IBIS 4.2.
Michael observed that, in order to allow at least three weeks to review
the complete 4.1 draft once all open BIRD proposals have been addressed,
the final reading and approval vote cannot take place before the
Open Forum meeting on January 30, 2004. This assumes that no further
BIRD reports are received and that BIRD85 and BIRD86 are resolved during
the January 9 meeting.
Michael also reiterated his suggestion that, to address BUG80
appropriately,
a hierarchy similar to the ICM and unofficial IBIS tree document should
be included within the IBIS specification itself. Participants agreed
that inclusion of the tree should be deferred until IBIS 4.2
Bob observed that, similar to the tree, the BNF description for the IBIS
specification has not been revised since IBIS 3.0. This should be
updated,
though it may be released only as a separate document.
A draft version of IBIS version 4.1 is available on the web. Both an
ASCII text and an Adobe PDF version are available at:
http://www.eda.org/pub/ibis/ver4.1_wip/
Note that the text of BIRD83 and BIRD84 has been included in the latest
draft.
NEXT MEETING
The next Open Forum teleconference has been scheduled for January 9,
2004
from 8:00 AM to 10:00 AM US Pacific Standard Time. Votes regarding the
approval of BIRD85.3 and BIRD86.1 are scheduled.
Thanks to all Open Forum participants and contributors in 2003!
