would like Bob Ross to check over the site. Bob accepted the AR. Bob
mentioned seeing an article in the February 14, 2005 EE Times magazine on
"IBIS can help Model Gigabit Pre-emphasis". The article was written
by Arpad Muranyi, Michael Mirmak, and Donald Telian.
NEW MODELS AVAILABLE, LIBRARY UPDATE
Michael Mirmak reported for Lance Wang that there has been no new model
activity.
MISCELLANY/ANNOUNCEMENTS
None.
OPENS FOR NEW ISSUES
Bob Ross requested that DAC planning be discussed as well as a discussion
on Michael Mirmak's plans for coverage during his time off.
MAILING LIST ADMINISTRATION
Bob Ross reported that things have been working normally. The eda.org mail
list administrator has been looking at editing of the email archives to
remove the ability of spammers to find email addresses from the archives.
INTERNATIONAL/EXTERNAL PROGRESS
Michael Mirmak gave a presentation on Monday, February 14 to the Verilog-AMS
working group. During the teleconference, questions were posed regarding
which features of AMS that IBIS is interested in using. Feedback from the
IBIS group was requested regarding implementation of table model functions
in Verilog-AMS. There are no plans to report to that working group again in
the near future. Michael received another invitation to attend the VHDL-AMS
working group meeting on Wednesday, March 9 at DATE.
SUMMITS
- DesignCon IBIS Summit, January 31, 2005, Santa Clara, CA
Michael Mirmak summarized the DesignCon 2005 IBIS Summit meeting. 54
members officially attended as logged with the GEIA. Many expressed
specific interest in BIRD95. There was a very full agenda, and Michael
would like to keep this level of interest at future summits. Bob Ross
thanked Cisco and Cadence for sponsoring refreshments. Michael thanked
Mentor for taking care of the booth. The IBIS sign was missing from the
booth, so this needs to be replaced. John Angulo will talk with Michael
offline about where to store the booth in the future.
- 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 has concluded making arrangements for
the room and other logistics. The third announcement was sent out.
Zuken, Mentor, Cadence, and Seimens are sponsors. Several papers are
planned. Bob Ross mentioned that on Thursday, March 10 there is a PCB
symposium at DATE that is free to those who register with DATE. Eckhard
Lenski will make a presentation on "Support of IBIS Models in a Modern
Design Flow." Bob said that the final agenda should be sent out on
March 4.
- JEITA IBIS Event - Japan, March 24, 2005, Tokyo, Japan
Michael Mirmak reported that travel arrangements are being finalized for
the JEITA IBIS event. People can contact Michael Mirmak with questions.
- DAC IBIS Summit
Bob Ross reported that DAC is held in Annaheim, California from June
13-17. A room needs to be reserved for 30-35 people. Tuesday, June 14
would be the Summit. It needs to be discussed at a later time the
possibility of having an exhibition booth to increase participation and
visibility. John Angulo said that Mentor is looking into the room
reservations already. Sponsorship is essential for this and welcome.
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 GEIA had sent results of the IBIS 3.2
reballoting. Of 23 active members that ballots were sent to, 20 members
responded. All responses were positive, so the ballot passed successfully.
Michael Mirmak thanked everyone for responding to the ballots.
S2IBIS3 STATUS
Ambrish Varma reported that he added support for Eldo simulation. He also
added the algorithms for clamp subtraction. A final version will be posted
on the website soon. Bob Ross asked if both clamps are subtracted for open
drain and open source driver cases? Ambrish believes that all models are
handled similarly, but he will check on that.
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 he is meeting with Jon Powell tomorrow. They are
ready to release the code as version 4.1.0.
ICM SPECIFICATION AND PARSER STATUS
Michael Mirmak reported that we are starting the reading process for ICM
1.1. The first official reading will be at the next meeting. A cleaned-up
copy of the specification will be released before the next meeting.
IBIS QUALITY COMMITTEE
Bob Ross reported that the committee met February 15th. The next meeting is
March 1. The committee is deciding which additional checks they would like
recommend as additions the parser and the quality document.
IBIS MODEL REVIEW COMMITTEE
No report.
FUTURES AND COOKBOOK COMMITTEES
Michael Mirmak reported that the committees met yesterday. The Cookbook
committee reviewed the latest draft of the cookbook, and it looked good.
The Futures committee discussed ICM links and BIRD95. The committees
meet every two weeks.
Recent committee material is stored at:
http://www.ibis-information.org/futures/
NEW ADMINISTRATIVE ISSUES
Michael Mirmak will be on sabbatical shortly after his trip to the JEITA
IBIS event. He will be out of contact March 25 through the month of April.
He may be available for the May 3 meeting. Syed Huq will run the meetings
in Michael's absence. All invoicing issues with the GEIA should be taken
care of before Michael leaves.
BIRD96: [MODEL SPEC] AND [RECEIVER THRESHOLDS] ORDERING
Randy Wolff mentioned that he had not received any comments expressing
issues with the BIRD. No concerns were raised during discussion. There was
a call for vote for inclusion of BIRD96 into the next version of the IBIS
specification. The BIRD passed unanimously with the following vote tally:
Cadence - yes
Cisco - yes
Intel - yes
Mentor - yes
Micron - yes
Samtec - yes
Siemens - yes
Teraspeed - yes
Xilinx - yes
COMPLEX I/O, MACROMODELING AND IBIS 4.1 - EXTENDED DISCUSSION
Donald Telian began the discussion. He asked everyone to open up the
presentation file that Michael previously sent out the link for. The files
referenced during the discussion are listed below. Donald noted that there
is a rapid increase in transistor model usage currently. The industry as a
whole recognizes IBIS as the best approach for behavioral modeling. AMS and
Spice are appropriate languages for behavioral macromodels. He said that
IBIS could offer the industry templates of how to use these languages to
create models. Within the industry he found a definite unfamiliarity with
the AMS languages. He stressed that the [External Model] Spice option was
very important to discuss. Cadence's use of Spice macromodeling has made it
easy to implement new keywords through macromodeling around a basic
B-element. Donald suggested an improved IBIS 4.1 Spice option to give users
the opportunity to do themselves what Cadence has done behind the scenes
from the start. Michael Mirmak asked how this is different from AMS?
Donald views them as complementary, that you can do it in whatever language
you understand better. Syed Huq asked if behavioral Spice is a macromodel?
Donald replied that behavioral Spice is narrower. Syed asked if runtime
improvements over Spice are seen using Spice macromodeling? Donald said
that the same improvement can be seen as using native IBIS. Ian Dodd
mentioned that Spice is not necessarily slow, and that it all depends on the
simulator. Donald said that Berkeley Spice is missing some important
things. The key element missing is an IBIS driver (B-element). Also,
parameter passing is missing. Donald said that IBIS 4.1 points to AMS, but
where it supports Berkeley Spice, that needs to be replaced as Berkeley
Spice plus the B-element, parameter passing, and table based EFGH elements.
Itzik Peleg asked why not just support HSPICE? Michael Mirmak responded
that it is not an industry standard, and we do not want to bless a
particular tool through the specification. Ian Dodd said that his customers
are interested in more Spice based solutions. Donald would also like to see
the creation of an IBIS 4.1 complex I/O template repository. Further
discussion will ensue at the Futures meeting and at the next teleconference.

BIRD95: POWER INTEGRITY ANALYSIS USING IBIS - EXTENDED DISCUSSION
Syed Huq mentioned that BIRD 95 will be split into three parts. I-t tables
will remain as the core of BIRD95. Michael Mirmak said that the split up
of the BIRD provides natural breaks between changes to the specification.
ICM links and ICEM links are now separate BIRDs. Michael asked if we know
all the pieces that need to be part of BIRD95.2. Bob Ross said that he will
look at if Z_vddq pieces can be fit into this BIRD. Syed received email
questions about core modeling from Norio Matsui. Arpad asked what needed to
be done about gate modulation effects? Syed would like to see gate
modulation as a separate BIRD. Arpad will pursue this.
BIRD94: CLARIFICATIONS ON [DIFF PIN] PARAMETERS
Discussion was deferred until the next meeting.
IBISCHK4 BUG STATUS
No report.
ICMCHK1 BUG STATUS
None to report.
NEW TECHNICAL ISSUES
None.
NEXT MEETING
The next IBIS Summit will be held March 11, 2005 at DATE. No
telephone bridge is available. An Open Forum teleconference has been
scheduled for March 11, 2005 from 8:00 AM to 10:00 AM US Pacific Time. The
JEITA IBIS Event will be held March 24, 2005 in Japan. No telephone bridge
is available.
