to IBIS.
Stephen Peters reported that Syed Huq is making ongoing updates to the IBIS
roster and upcoming events link.
NEW MODELS AVAILABLE, LIBRARY UPDATE
None.
OPENS FOR NEW ISSUES
Stephen Peters requested to add a discussion of the upcoming IBIS officer
election to the agenda.
INTERNATIONAL/EXTERNAL PROGRESS
- IEC 62014-3 (ICEM) Integrated Circuit Electromagnetic Model Proposal
(formerly, IEC 93/67/NP IBIS and EMC Simulation) - No report.
- JEDEC Activity Report. Lynne Green reported that 35 persons attended her
IBIS Modeling class at the JEDEX conference on March 24, 2003 in San
Diego, California. Seminar A was entitled "An Introduction to IBIS
Models and Model Validation." Seminar B was called "IBIS Models for
High-Speed Interfaces." Class material is not yet available on the web.
DATE2003 EUROPEAN IBIS SUMMIT MEETING REPORT
Eckhard Lenski gave a brief report on the European IBIS summit. Eckhard
noted that only one EDA vendor was in attendance. Eckhard also remarked
that there were questions on the status of various IBIS projects, and it
would have been good to have an IBIS officer in attendance to answer those
questions.
Bob Ross reported positive comments from several people who attended. The
presentations were interesting and informative, and people enjoyed good
interaction.
Bob noted that a DATE2004 meeting is scheduled in the Paris area in April
2004. We will put it on the Upcoming events link. Chances are good that
Zuken will be able to help again on this meeting.
DAC2003 AND DESIGNCON2003 EAST MEETING PROPOSALS
Stephen Peters indicated that we need to decide on holding an IBIS Summit
meeting at DAC2003 in Anaheim California on Thursday, June 5, 2003. John
Angulo reserved a room through Mentor Graphics at the Marriot Hotel, but
needs a quick decision. We are planning to also hold a meeting at the
DesignCon East conference in Marlborough, Massachusetts on Monday, June 23,
2003.
Stephen reported that as much as he would like to be able to attend and
hand off the chairmanship, he will not be able to travel to DAC this year.
He also noted that early indications are that membership will be down
this year, and that we need to keep in mind that the hotel room and
conference will cost on the order of $2,000USD.
In the following discussion, Lynn Green indicated that she can attend.
Representatives from Mentor Graphics and Intel will also be attending.
Arpad Muranyi noted that many persons plan on attending the June DAC
conference, and for consistency we should continue to hold this meeting.
It was noted by several folks that whatever we decide there is no reason
not to hold a summit at DesignCon East. After further discussion we
agreed to hold an IBIS summit meeting at DAC on June 5th.
Stephen reported that planning for an IBIS summit meeting at Designcon2003
East in Marlborough, Massachusetts continues. The summit is scheduled for
June 23, 2003 in the Royal Plaza Hotel in Marlborough, Massachusetts. The
meeting room is yet to be determined. Stephen noted that we are also a
co-sponsor of DesignCon2003 East. Barry Katz from SiSoft has indicated that
he is willing to serve as the contact for registration and sign-up, so if
you are planning on attending please let Barry know. The upcoming events
link on the IBIS web page will be updated with more details as they become
available. Finally, Stephen mentioned that we have traded refreshments for
a telephone line so that the meeting can be web telecast. Bob Ross remarked
that we will be soliciting companies to sponsor the lunch.
It was noted that we will need to obtain an LCD projector for the room at
DAC. Guy de Burgh will check on projector availability. Finally, Stephen
mentioned that announcements for both the DAC and DesignCon East summit
meetings will go out early next week.
IBIS VERSION 4.0 PARSER FUNDING AND STATUS
Stephen Peters reported that the EIA has received IBIS 4.0 parser payments
from five companies, with three more pending. Stephen is working with EIA
to get updated numbers.
UPCOMING IBIS OFFICER ELECTIONS
Stephen Peters announced that the annual election of IBIS officers will be
held at the June 5, 2003 summit meeting at DAC. Officer positions are open
to representatives of any member company, and nominations are open from now
until the election. You need not attend the summit meeting in person to
be elected.
Stephen also announced that he will not run for a third term as IBIS chair.
Stephen asked for early nominations for IBIS chair, and Bob Ross nominated
Michael Mirmak to serve as IBIS Chair for 2003-2004. Stephen stated that
nominations for the other IBIS officer positions are welcome, however please
check with the nominee beforehand to ensure that they are willing to serve.
Stephen noted that Lynne Green, Randy Wolff, Syed Huq, Roy Leventhal and
John Angulo have all agreed to continue in their current positions of
Vice-Chair, Secretary, Webmaster, Librarian, and Postmaster respectively.
IBIS QUALITY COMMITTEE
Bob Haller reported on the IBIS Quality Committee meeting on March 25, 2003.
The next meeting is scheduled for April 8, 2003. The Quality Committee is
continuing to work on the quality checklist, compiling individual sections
into one document. The goal is to have a draft document available at
DesignCon East. Bob noted that there was a lot of interest expressed in
IBIS quality at the European IBIS Summit, and he also expects good
attendance from Quality Committee members at the DesignCon East Summit in
June.
IBIS MODEL REVIEW COMMITTEE
Lynne Green reported that a model from the Marvell Technology Group has
been distributed to committee members for review.
NEW ADMINISTRATIVE ISSUES
None.
IBIS FUTURES AND CONNECTOR WORKING GROUP REPORT
Stephen Peters reported that the IBIS connector working group met on March
13, March 21, and again on March 27, 2003. The editorial and technical
issues raised previously have all been addressed, but several new issues
dealing with S-parameter representation and usage have been raised. The
committee is working through these issues and expects to do a final read
through of the document at their next meeting on April 4, 2003. Stephen
expects a final draft of the Rev. 1.0 ICM specification to be available
for IBIS Open Forum review by April 15, 2003.
In response to a question from Michael Mirmak, Stephen stated that we
would review and accept comment on the ICM specification for a period of
three teleconference meetings before putting it up for a formal vote. This
will give time for comment, as well as additional testing by the parser
developer.
On a related topic, Arpad Muranyi noted that he has sent Stephen a list of
editorial comments on the Touchstone format specification that appears on
the IBIS website. Arpad asked how these comments should be handled. After
a short discussion it was agreed to review these comments in the next
connector working group meeting. Arpad will forward his comments to the
connector working group members. Stephen noted that we will formally
consider adopting the Touchstone format specification document along with
the ICM specification.
BIRD79 - Non-linear buffer impedance (extension to C_comp)
Stephen Peters opened the discussion on BIRD79 by summarizing the previous
discussions on this BIRD. The consensus was that modeling the effects of
non-linear buffer impedances is best done using the multi-lingual modeling
extensions to IBIS. Because of this, BIRD79 should be rejected and instead
the methodology should be documented in a technical paper. BIRD79 co-author
Luca Giacotto agreed with this recommendation. After a formal vote BIRD79
was rejected. Luca agreed to work with Arpad Muranyi to author a technical
white paper on modeling the effects of non-linear output impedance in
IBIS using the multi-lingual extensions. In response to a question from
Arpad, it was agreed that this paper should include an implementation
written in one of the -AMS languages.
BIRD74.2 - EMI Parameters
Guy de Burgh stated that Eckhard Lenski at Siemens and the representative
from Zuken are still very interested in BIRD74 and would like to see
further discussion of including EMI modeling in IBIS. Stephen Peters
agreed to defer a vote on this BIRD. Guy agreed to put together a review
of BIRD74 for discussion at the next teleconference meeting. Bob Ross noted
that the EMI modeling parameters and information introduced by BIRD74 are
not something covered by the multi-lingual modeling extensions. Bob also
noted EMI modeling should be targeted for an IBIS release beyond the pending
IBIS 4.1.
IBISCHK3 & BUG TRACKING STATUS
In follow-up to last teleconferences discussion on bug fixes, Stephen
Peters reported that Atul Agarwal has agreed to incorporate the fixes for
BUG75, BUG76 and BUG68 into the code for the IBIS 4.0 parser.
John Angulo reported that he has taken a preliminary look at BUG68 and
BUG73. BUG68, entitled "False messages with Repeated Voltages", is a very
simple fix. However, BUG73, entitled "Extreme Non-monotonic I-V Tables Cause
End Point Test to Fail," is more complicated. In brief, non-monotonic
points in the clamp table cause the parser to extrapolate the table
endpoints incorrectly, thus the end point test fails. After further
discussion it was decided that John will pursue this problem further and
propose a specific fix. Arpad Muranyi requested that he be involved in
reviewing the proposed fix.
- BUG71 - Monotonic Checking for Combined I-V Tables
Stephen Peters will post Bob Haller's response to the reflector for
discussion and resolution at the next teleconference.
- BUG74 - Missing Timing Test Load Warning Messages
Stephen Peters will post the clarification text to the IBIS reflector for
discussion and disposition at the next teleconference.
NEXT MEETING:
The next teleconference meeting is scheduled for April 18, 2003 from 8:00
AM to 10:00 AM Pacific Daylight Time.
