INTRODUCTIONS AND MEETING QUORUM
No new participants.
CALL FOR PATENTS
Michael Mirmak called for any patents or pending patents related to the
IBIS Version 3.2, 4.0, 4.1, 4.2, or ICM 1.1 specifications. No patents
were declared.
MEMBERSHIP UPDATE AND TREASURER'S REPORT
Michael Mirmak reported that as of the latest update from GEIA (ITAA), we
have 19 members paid and are waiting on 9-10 other renewals. The roster
will be completely updated at the DAC summit to drop non-renewed members.
REVIEW OF MINUTES AND ARS
Michael Mirmak called for comments regarding the minutes of the April 25,
2008 IBIS Open Forum teleconference. The minutes were approved without
changes.
WEB PAGE UPDATES
Bob Ross noted that the upcoming events page was updated.
MAILING LIST ADMINISTRATION
Bob Ross reported that everything is working normally.
MODEL LIBRARY UPDATE
No update.
PRESS UPDATE
None.
MISCELLANY/ANNOUNCEMENTS
None.
OPENS FOR NEW ISSUES
Michael Mirmak mentioned that the GEIA, parent organization of IBIS, has
now made its Manual of Operations and Procedure, plus its Style Manual for
Standards and Other Publications, available for download free of charge.Â
We have received several queries regarding GEIA procedures on patent,
copyright and other intellectual property questions. The Manual of
Operations and Procedure should serve as the guide to policies followed by
the IBIS Forum. The manuals are found at:
http://www.geia.org/index.asp?sid=6 (scroll to the bottom)
INTERNATIONAL/EXTERNAL PROGRESS
- DASC
Michael Mirmak noted that there have been no meetings recently, and the
meeting at DAC has been cancelled. The DASC website is found at:
http://www.dasc.org/
- P1735 Encryption
No update. The IEEE DASC Study Group on Encryption web site is found at:
http://www.eda-stds.org/ip-encrypt/hm/
IEC APPROVAL ACTIVITIES
Randy Wolff noted that he contacted John Messina from NIST by email
regarding IEC approval. He and John are still trying to work out a time
for a phone conversation. He hopes to talk with him next week. Michael
Mirmak asked Arpad Muranyi if he could contact Dennis Brophy at Mentor.
Michael will send Arpad contact information for Dennis.
SUMMIT STATUS
- DAC Planning
DAC will be held June 9-13, 2008 in Anaheim, CA. Tuesday, June 10 is
scheduled for the summit meeting. Syed Huq is the main contact for the
event. A room has been arranged in the Anaheim Marriot hotel, adjacent to
the convention center. Several presentations have been scheduled already.
Please submit presentation titles soon. Three presentations are officially
scheduled, but there are six at least. Michael Mirmak announced that he
will be making a presentation on [Driver Schedule] and [Test Data] test
loads. Elections will be held for officers. If you are interested in
running for any officer positions, the board is strongly encouraging people
to run as all current officers are willing to serve again but also would
step aside to allow new participants. Another announcement will be out in
a week and the agenda a week before the event.
- Asian Summits Planning
Michael noted that he established contact information in Taipei, Taiwan,
and sponsors are being sought. Note that business visas in China may be
more difficult to obtain due to the Olympics. A sponsorship letter may be
needed. The planning group will firm up the China date soon. The summits
will be held in the November-December timeframe.
Sponsorship opportunities for the DAC IBIS summit are available, with
sponsors receiving free mentions in the minutes, agenda, and other
announcements. Contact the IBIS Board for further details.
IBIS QUALITY TASK GROUP
Bob Ross reported that the group has been discussing aspects of overshoot
parameters and [Test Data] and [Test Load] details. Meetings have not been
held in two weeks but will resume next week.
The Quality Task Group checklist and other documentation can be found at:
http://www.eda-stds.org/ibis/quality_wip/
IBIS MODEL REVIEW TASK GROUP
No update.
ADVANCED TECHNOLOGY MODELING TASK GROUP
Arpad reported that the group has been reviewing the EMD proposal by Walter
Katz. They are trying to figure out whether to go forward with EMD,
improve ICM, or go forward with both. There have also been recent
discussions on the reflector of support for the sliding window algorithm in
IBIS AMI. There are no clear requirements on models currently, but Arpad
plans to work with Cadence to implement this in their example model.
Task group material can be found at:
http://www.eda-stds.org/ibis/macromodel_wip/
AD HOC TASK GROUPS (INTERCONNECT)
Michael Mirmak reported that the group has not met for several weeks. They
will resume meeting next week. There have been discussions of mixed mode S-
parameter formats on the reflector. Bob Ross added that the group has come
to agreement in reflector discussions on the technical content of mixed
mode support. Arpad Muranyi asked if the Interconnect task group should
start discussing ICM changes. Michael responded that the group can begin
discussing this, but it will be slow progress until Touchstone 2.0 is
finished in the task group.
Task group material can be found at:
http://www.eda.org/ibis/adhoc/interconnect/
NEW ISSUES
Arpad Muranyi opened up a discussion on the requirement for the sliding
window algorithm in IBIS AMI. Potentially a clarification BIRD will be
needed. The IBIS AMI spec says that EDA tools “may†call AMI_Getwave
functions multiple times and break up an entire waveform into smaller
pieces for processing. It is not specifically stated in the specification
that models must provide for support of the sliding waveform algorithm and
buffer waveforms if necessary. He asked if we should we add some text to
the AMI BIRD to clarify that this is an absolute requirement. Todd
Westerhoff agreed that the text is not crystal clear on this issue, but it
is implied that this algorithm must be supported. Todd suggested that we
handle this issue at a later time. A novice model maker may not understand
this, but an experienced one would. Todd does not want to hold up the IBIS
5.0 specification for this issue. Bob Ross agreed with this approach. A
BIRD will probably be written at a later time.
BIRD105: MANDATORY GOLDEN WAVEFORM DATA
Anders Ekholm noted that the Quality task group has been discussing the
Golden Waveforms structure in the specification. There are many
limitations and changes may be needed. He does want to encourage the use
of Golden Waveforms but realizes that making them required in all models is
not the best approach. He suggested bringing up the BIRD for a vote at the
next meeting and recommended a “no†vote. The Quality group has discussed
adding a quality designation for Golden Waveform inclusion in a model.
A vote will be scheduled at the next meeting.
BIRD106: CLARIFICATION ON SIGNAL_PIN PARAMETERS
Arpad Muranyi noted that no changes have been made. It is ready for a
vote. A vote was called for to include BIRD106 in the next version of
IBIS. The vote passed unanimously with the following vote tally:
Ericsson Yes
Huawei Yes
IBM Yes
Intel Yes
IO Methodology Yes
LSI Yes
Mentor Yes
Micron Yes
SiSoft Yes
Teraspeed Yes
BIRD107.2: UPDATE TO ALGORITHMIC MODELING API (AMI) SUPPORT IN IBIS
Todd Westerhoff noted that the BIRD is up to date and ready for a vote. A
vote was called for to include BIRD107.2 in the next version of IBIS. The
vote passed unanimously with the following vote tally:
Ericsson Yes
Huawei Yes
IBM Yes
Intel Yes
IO Methodology Yes
LSI Yes
Mentor Yes
Micron Yes
SiSoft Yes
Teraspeed Yes
BIRD108: FIXING ALGORITHMIC MODELING API IMPULSE_MATRIX NOMENCLATURE
Bob Ross introduced the BIRD. It is a text correction to the original IBIS
AMI BIRD. Impulse_Matrix is described with a “_†in the text but not in
the table in the Algorithmic Modeling section. This BIRD needs to be
included tin the next version of the IBIS specification along with BIRD
104.1. This does not change any technical content of BIRD 104.1; it is
only an editorial change. A vote will be scheduled for the next meeting.
BIRD109: S_OVERSHOOT_HIGH/S_OVERSHOOT_LOW CLARIFICATION
Anders Ekholm introduced the BIRD. It is a clarification BIRD. The
current specification does not make a distinction between absolute maximum
(destruction) ratings and functional ratings for device
overshoot/undershoot. This BIRD adds clarification to the IBIS
specification that functional information, not destruction information
should be included in an IBIS model. BIRD109 will be scheduled for a vote
at the next meeting.
IBIS 5.0 DRAFT REVIEW
Michel Mirmak issued a call for comments regarding the draft document. Bob
Ross noted that all current BIRDs are slated for inclusion in IBIS 5.0. He
needs to work on a cleaned up version of the document to remove comments.
Michael asked Anders Ekholm about BIRD109 inclusion in IBIS 5.0. Anders
expected to include BIRD109 in IBIS 5.0, but the Golden Waveforms topic
requires a lot more discussion and may end up with changes in an IBIS 5.1
document.
