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 1.0 specifications. No patents were
declared.
MEMBERSHIP UPDATE AND TREASURER'S REPORT
Michael Mirmak reported that there is no update of membership numbers since
the last report. The invoicing list for 2005 is being assembled by GEIA,
and invoices will be sent out shortly. Michael encouraged everyone to be
sure that contact information is correct as listed on the IBIS website.
Invoices will be received by email from Marina Spivey of GEIA.
REVIEW OF MINUTES AND ARS
Michael Mirmak reviewed the minutes of the November 19, 2004 IBIS Open Forum
teleconference. The minutes of the meeting were approved without change.
PRESS AND WEB PAGE UPDATES
Syed Huq reported that Xilinx has been added to the roster as a new member
for 2005. Poster changes have been sent to GEIA and should be up within a
day.
NEW MODELS AVAILABLE, LIBRARY UPDATE
Michael Mirmak reported for Lance Wang that GEIA has received an updated
model library page with one company added with a new model link. The change
will be posted shortly.
MISCELLANY/ANNOUNCEMENTS
None.
OPENS FOR NEW ISSUES
Bob Ross requested that a discussion ensue on the IBIS Committee funding
model as an overview for new members. Bob explained that funding is through
dues with most going to cover GEIA dues. GEIA creates an IBIS assessment of
about $18,000 per year that is used by the IBIS committee during the year to
pay for various expenses. Parser development requires additional money, but
conferences are covered by dues and sponsors.
MAILING LIST ADMINISTRATION
No update.
INTERNATIONAL/EXTERNAL PROGRESS
Michael Mirmak reported on work group relations with IEEE/DASC on VHDL-AMS
and Accellera on Verilog-AMS. There is a possibility of an introduction to
IBIS at an upcoming Accellera Verilog-AMS meeting. There have been positive
responses so far from both groups on continuing IBIS interaction with them.
SUMMITS
- DesignCon IBIS Summit, January 31, 2005, Santa Clara, CA
DesignCon 2005 will take place January 31 - February 3, with a Summit
scheduled for Monday, January 31. Syed Huq mentioned sending out the first
call for papers. Syed reported that five people signed up, but a quick
poll at the meeting indicated an estimate of 15 people so far with many
more to sign up later. The luncheon involvement deadline is January 15.
DesignCon must be notified on this date of the number of IBIS attendees
that will be eating lunch. Michael Mirmak mentioned that a short IBIS
description will be in the DesignCon booklet as well as other
publications. Michael is unsure of the booth location. Refreshments are
still being discussed with DesignCon.
- DATE European IBIS Summit, March 11, 2005, Munich, Germany
DATE 2005 will take place in Munich, with a Summit planned for Friday,
March 11. Ralf Bruening of Zuken is making arrangements for the room
and other logistics. An update is needed from Ralf.
- JEITA Asian IBIS Event, March 24, 2005, Tokyo, Japan
Michael Mirmak reported that JEITA members are still in the planning
stages. JEITA would like to have an IBIS related event, but they want it
to be a closed meeting and not a summit. There has been a proposal to
make IBIS attendees guests of JEITA as IBIS delegates.
Sponsorship opportunities for all these Summits are still available, with
sponsors receiving free mentions in the minutes, agenda, and other
announcements.
IBIS ANSI BALLOT STATUS
Randy Wolff reported that the IBIS 3.2 reapproval ballots are due December
23. GEIA has sent out one reminder email, and one more email will be sent
before the ballot closes. It was mentioned that only IBIS committee voting
members vote on the ballot. Multiple people from a member company may
vote; however, the vote of only one member of each organization will be
counted. This voting member is identified by GEIA. Michael Mirmak
mentioned that he had received a spreadsheet from GEIA showing current vote
tallies and indicating member companies with invalid email addresses. It
was determined that the IBIS committee will need to update as many of the
invalid email addresses as possible and ensure that these members receive
their ballots. Randy, Michael, and Bob Ross took the AR on this.
S2IBIS3 STATUS
No update.
S2IBIS3 beta executables can be downloaded from:
http://www.ece.ncsu.edu/erl/ibis/s2ibis3/s2ibis3.htm
Feedback on the current version is appreciated and encouraged.
IBIS VERSION 4.1 PARSER STATUS
Bob Ross reported that most issues have been resolved and closed with
respect to how John Powell will interpret the specification. There are
three or four more issues to raise on how to interpret the specification
given how the parser has been developed. Bob may be developing BIRDs to
close these issues. The parser is still on schedule for release early
next year.
ICM SPECIFICATION AND PARSER STATUS
Michael Mirmak reported that Kelly Green is addressing a bug reported in
the parser. There have been 8 IIRDs filed, with 5 approved, 1 rejected,
and 2 pending. Michael proposed cutting off the changes allowed with
IIRD8.1 in order to finish the parser and move forward with ICM 1.1 approval
and ANSI/GEIA balloting to make it an official standard. The committee is
in agreement with Michael's proposal. Lynne Green mentioned that we should
encourage people to make some ICM models to see how people are interpreting
the specification.
IBIS QUALITY COMMITTEE
Bob Haller reported that the committee met December 7 and continues to meet
on the first Tuesday of each month. An action item from the last meeting is
for each committee member to contact one vendor about beta testing the
checklist. The committee is also trying to figure out ways to automate the
checklist. Mike LaBonte has generated a list of checks to submit as parser
bugs. Bob Ross proposed a command line switch in the parser to generate
extra cautions as suggested by the quality checklist.
IBIS MODEL REVIEW COMMITTEE
Lynne Green reported receiving questions from ST Microelectronics. Lynne
would like to encourage that people use a parser version that is newer than
3.2.7, such as 4.0.2.
FUTURES AND COOKBOOK COMMITTEES
Michael Mirmak reported that both committees met last Thursday and continue
to meet every two weeks. The Cookbook committee's latest cookbook draft
includes revisions to the [Pin Mapping] and [Series *] descriptions. A
major overhaul to the clamp curves section is in progress. The Futures
committee discussed parser issues of IBIS 4.1 and the hierarchy of
[External Model], [External Circuit], and [Model] keywords as well as
integration of ICM. Some BIRDs will be introduced soon.
Recent committee material is stored at:
http://www.ibis-information.org/futures/
NEW ADMINISTRATIVE ISSUES
None.
BIRD92.1: MULTIPLE TERMINATOR AND SERIES ELEMENTS UNDER [MODEL]
Michael Mirmak reported that a question arose recently on how [On] and [Off]
keywords are treated with respect to [Model] type Series and not just
Series_switch. Michael said that this will need to be thoroughly checked
before voting on the BIRD. Voting was postponed.
BIRD93.1: MODEL AND SIGNAL NAME LIMIT EXTENSION
Michael Mirmak summarized the BIRD. It lengthens model_name and signal_name
fields from 20 to 40 characters. The added length of these fields still
fits within the 120 character line length limit. Donald Telian was
concerned with implementation of this in tools. Increasing the number of
characters could require lengthening of fields in GUI boxes. Michael
mentioned making suggestions in the cookbook to keep names as short as
possible. A vote was called for and seconded. Pursuant to GEIA rules, the
vote tally per organization is now recorded in the minutes. The BIRD was
approved with the following vote tally:
Cadence Design Systems - abstain
Intel - yes
LSI Logic - yes
Mentor Graphics - yes
Micron - yes
Signal Integrity Software - yes
Teraspeed Consulting Group - yes
IIRD2.3: FREQUENCY DEPENDENT RLGC MATRICES
Vote postponed due to lack of available discussion time.
IIRD8.1: DISTINCT MODEL_PINMAP AND MODEL_NODEMAP NAMES
Bob Ross reported receiving a comment that the description of the side
subparameter needs to be made more clear. The vote was postponed to allow
for time to address this comment.
IBISCHK4 BUG STATUS
Michael Mirmak reported that no BUGs have been filed.
ICMCHK1 BUG STATUS
BUG1: TEXT BLOCK OVERFLOW FOR VERY VERBOSE MODE
Michael Mirmak reported the filing of this BUG. The very verbose mode is a
mode of the parser used for debugging. The length of certain text blocks in
the model cause the parser to crash. It was determined that no interim
release of the parser is needed to fix this BUG. The BUG can be fixed along
with other IIRDs in the next official release. The BUG report was classified
as Open, Moderate, with Medium priority.
NEW TECHNICAL ISSUES
None.
NEXT MEETING
An Open Forum teleconference has been scheduled for January 7, 2005
from 8:00 AM to 10:00 AM US Pacific Time.
