-------------------------------- MINUTES -------------------------------------
INTRODUCTIONS
None. Will Hobbs chaired the first 35 minutes of the meeting, and Jon Powell
chaired the rest of the meeting.
EIA MEMBERSHIP AND TREASURER'S REPORT
The treasury is still about $8725.54, although one charge against the
account is pending. Patti Rusher indicated that TI plans to purchase the
ibischk2 source code.
MINUTES REPORT, MISC.
None.
MISCELLANY/ANNOUNCEMENTS
Bob Ross reported that there have been updates in the contents of vhdl.org
under the /pub/ibis directory including all of the birds under birds,
frequently asked questions under faq, ibischk2 executables under ibischk2,
and meeting minutes in text form for all years. Also roster.txt has been
moved to roster/roster.txt, and pressrel.dir has been changed to pressrel.
Jon Powell reported that H.A.S. Electronics, Inc. at haselect@aol.com has
advertised IBIS models.
PRESS UPDATES
Will Hobbs reported that the October 16, 1995 front page EE Times Article
on the P6 referred to I/O models (IBIS models) described in the P6
Users manual.
NEW MODELS
None reported. [P6 Models not requiring NDA will be available November 1.]
OPENS FOR NEW ISSUES
Ground Bounce per some recent reflector discussion.
EIA IBIS RATIFICATION
Patti Rusher reported that EIA-656 was OFFICIALLY RATIFIED October 26, 1996
by EDAC. It is being forwarded to ANSI, hopefully for ratification by
the end of the year. During an EDA standards roadmap presentations, Don
Cottrel referenced IBIS and also raised some requests for additions to
better position IBIS.
EIA PRESS RELEASE
AR - Patti Rusher voluteered to send a draft of the EIA press release
for review. It will indicate EDA industry council interest in IBIS.
WEB UPDATE (AND EIA)
The delay in bringing up IBIS under //www.eia.org/eng is because of legal/
security/copyright concerns about what EIA can present on the Web Site.
This is applicable to all Standards, not just IBIS, This also relates
to funding from the sale of published documents copyrighted by EIA. This
should be resolved within two weeks. Patti Rusher is pushing for a
rapid resolution so that at least some of the IBIS material can be
presented soon.
Jon Powell has logos from eight companies to go on the Web page. Only
logos from EIA member companies will be used. This is an additional benefit
to become an EIA-IBIS member.
AR - Patti Rusher send to Jon Powell the list of member companies who
have supplied the required permission letters to use the logo.
FACE TO FACE MEETING
Syed Huq reported that the majority of respondents favored Monday,
January 29 before SuperCon96. He will schedule rooms and make arrangements
for National Semiconductor to host the meeting.
A possible celebration dinner for EIA-656 completion may be planned that
evening for those staying over.
MODEL USAGE TRACKING
Syed Huq reaffirmed the need and interest to track model usage. Stephen
Peters and Syed will seek help within their own organizations because
it is an internal issue regarding access through company Web pages.
Perhaps their solution will work on vhdl.org.
This raised a discussion on pointers to company home pages from EIA. This
is feasable and planned. So the possiblity exists that many companies
may have IBIS models available under their control and also include the
mechanisms to get the NDA models. One possiblility suggested by Jon Powell
is an interface which requests the user name before allowing access to
certain directories containing the IBIS models.
Kellee Crisafulli reported contact and interest by Xilinx to post models.
The decision is still being reviewed by management.
Sung Oh reported that VLSI wants to remain in control of distibution of
their IBIS models. People contact the sales force to get models.
GOLDEN PARSER UPDATE
Bob Ross has posted the executables created by Jon Powell for ibischk2
on vhdl.org under /pub/ibis/ibischk2. Currently it is a flat directory
with all executables appended by the associated workstation. The original
posting was corrupted, but the correct versions are now in place. So
if you had any problems, check that you have the current executable.
Report any problems.
Compiler information will be embedded in the executables, similar to
the ibis_chk executables for Version 1.1. Jon Powell will take care of
creating these after some time to check that there are no new problems.
They will then be designated ibischk2 and put under the appropriate
workstation directory similar to ibis_chk. The verion number will be
version 2.1.10 since these are IBIS version 2.1 (and below) executables.
SPICE TO IBIS VERSION 2.1
Bob Ross reported on the comment by Celso Faia of Unicad that a DOS
Windows version is needed. Kellee Crisafulli reported that he has been
unable to get Version 2.1 compiled, has been in touch with Michael Steer,
and may get some internal resources to help.
COOKBOOK
Bob Ross reported no progress. Since Stephen Peters of Intel is going
to do an internal update, he may be the key resource to get this done.
Similarly Syed Huq may have some inputs, especially for models from
measurements. So Kellee and Bob are turning this over to Stephen and
Syed. However, we will all be available to review and give inputs. Since
this can be an extra time work project, there is no date committment.
So it is taken off the Agenda.
BIRD30.2 - PIN PROGRAMMABLE BUFFER STRENGTHS
Arpad Muranyi discussed BIRD30.2 with a text revision. Some discussion
including its relationship to DCL (Delay Calculation Language) standardization
with respect to dynamically selectable buffers was initiated by Ron
Christopher. Several ideas to select models including ordering were
discussed. The concensus was that the actual selection basis was too
complicated to come to an agreement at this time. The description syntax
could be standardized, but proposals would have to be developed and
considered.
The current proposal allows manual selection through a graphical user
interface (GUI) with no standardization on descriptions. Jon Powell
stated that this could work for One device considerations, but the concern
is that it would be a very combersome process for working with a large
board with many IBIS model files from several vendors.
BIRD30.2 was approved by the Vote.
Proposals the improve upon BIRD30.2 would be considered.
BIRD28.3+ PACKAGE MODEL ENHANCEMENT
Stephen Peters reported on C. Kumar's proposed extension recently sent
on the reflector. The proposed extension would have to add a pin ordering
file and a Matrix name to allow a more general set of coupling relationships.
The primary concern was that it may be too close to an MCM discription
without including some physical information. This topic is still open
for discussion, and the proposed improvement by Kumar in BIRD format
could eventually emerge as a new bird to amend approved BIRD28.3
EGG6 - TTL and CMOS
Jon Powell reported that he is still investigating three suggestions
including one provided by Arpad Muranyi to automatically detect whether
a device is TTL or CMOS. He is pessimistic, but needs validation of
his position.
EGG7 - CONNECTOR AND CABLE MODEL
Bob Ross summarized the proposed Connector model extension which involves
no change of the IBIS Specification. It provides an interpretation of
the existing package model formats from the default model though the
Version 2.1 Matrix models up to BIRD28.3 extensions. Involvement by
a connector manufacturer such as AMP would be helpful to test the
practicality of this approach. Several names were suggested and Bob
will follow up.
The CABLE model would require new syntax and complication, but it could
then handle more complicated interconnection schemes with connection
from, say, pin 1 of board 1 to connection or pin 2 of board 2.
PHYSICAL PACKAGE DISCUSSION
Kellee Chrissafulli is nearing completion of a proposal for such an
extension. EGG8 is reserved for this.
GROUND BOUNCE
Bob Ross reported on recent Email from Michael Gutzmann, and this was
briefly discussed in the remaining time. One concern was whether there
were additional parameters or layout which would contribute to significant
inaccuracies beyond what the proposed improvement would cover. What accuracy
can be achieved and what accuracy currently exists? How are the real skew
effects handled? This topic remains open for discussion and proposals.
NEXT MEETING:
It is set on Friday, December 1, 1995 (Moved from November 17 because
several people would be out).
