INTRODUCTIONS AND MEETING QUORUM
No new participants.
CALL FOR PATENTS
Bob Ross called for any patents or pending patents related to the IBIS 3.2,
IBIS 4.2, IBIS 5.0, Touchstone 2.0 or ICM 1.1 specifications. No patents
were declared.
MEMBERSHIP UPDATE AND TREASURER'S REPORT
Bob Ross reported that 22 members have officially renewed. He is following
up with several more members. Another ibischk5 parser license has been
sold. This makes 9 parser sales so far. A Touchstone parser sale is being
closed as well.
REVIEW OF MINUTES AND ARS
Bob Ross called for comments regarding the minutes of the April 2, 2010
IBIS Open Forum teleconference. The minutes were approved without changes.
WEB PAGE UPDATES
Bob Ross noted that an ‘upcoming teleconference’ link was added to the home
page.
Syed Huq reported that ‘Working Directories’ and ‘About IBIS’ links were
added to the home page. All pages have moved to eda.org. He is still
working to fix links on the Articles page. The eigroup.org page is now
just a re-director to the eda.org site.
Michael Mirmak asked in relation to the pages for individual task groups,
is there an overhaul in progress for the quality or ATM site? Bob replied
that he is not aware of any in progress.
MAILING LIST ADMINISTRATION
Bob Ross reported that there are still bounces related to the Stanford
servers.
MODEL LIBRARY UPDATE
Anders Ekholm reported that the latest update was on April 7. He is
working on another update for mid-May.
Bob Ross asked if there were any further comments on crowd sourcing.
Anders looked at the web page from Colin Warwick, but it was not obvious to
him how it worked. He did not feel that enough IC vendors would be
interested in updating a crowd sourcing page. Bob noted that there was
interest in this concept from a poll conducted by Colin.
PRESS UPDATE
Bob Ross mentioned a book by Dave Coleman and Michael Mirmak titled
Mastering High Performance Multiprocessor Signaling. The book includes one
reference to IBIS. More information is available at:
http://tinyurl.com/28dyozu
MISCELLANY/ANNOUNCEMENTS
Bob Ross noted that the DesignCon show has been taken over by EETimes. He
is not sure what implications this will have for the conference.
OPENS FOR NEW ISSUES
Bob Ross noted that new parser BUGs, BUG115 and BUG116, will be discussed
later in the meeting.
INTERNATIONAL/EXTERNAL ACTIVITIES
- DASC
Michael Mirmak noted that the next meeting is two weeks from now. No
content pertinent to IBIS was discussed in the last meeting. The DASC file
and e-mail archive may be found at:
http://www.dasc.org/
- P1735 Encryption
No update. The IEEE Study Group on Encryption web reflector archives are
found at:
http://www.eda-stds.org/ip-encrypt/hm/
-Conferences
Signal Propagation on Interconnects Workshop (SPI) is May 9 - 12, 2010 in
Hildesheim, Germany. There is SI content and sometimes IBIS topics at this
conference. The European IBIS Summit will be held in conjunction with this
event on Wednesday afternoon.
http://www.spi.uni-hannover.de/
TECHAMERICA STATUS
No report.
IEC APPROVAL ACTIVITIES
Randy Wolff reported that he has had no further contact with Tim Rotti or
Victor Berman. He is unsure who contact for further information at this
point.
SUMMIT STATUS
-European Summit Planning
The summit is planned for Wednesday, May 12 from 12:30pm-5:30pm. This is
after the SPI conference, which ends at noon. It will be held at the same
hotel and location as the SPI conference in Hildesheim, Germany. Ralf
Bruening is helping with local arrangements. The third announcement went
out including a preliminary agenda. 9 or 10 presentations are scheduled.
15 people are signed up so far. Some WebEx meeting time has been reserved
as a backup in case there are travel delays related to the Iceland volcanic
eruptions. Agilent, Mentor, Sigrity, Sintecs and Zuken are co-sponsors.
-DAC Summit Planning
The DAC summit is planned for Tuesday, June 15 in Anaheim, CA.
Traditionally this meeting is the annual meeting with the election of
officers. The first announcement will go out after the meeting. Lance
Wang will handle the signups. Bob Ross noted that the exhibition is free
on Monday.
-Asian Summits Planning
The planning committee is discussing three potential summits this year in
China, Japan and possibly Taiwan. Lance Wang reported that he is working
on the China summit. The meeting will be held the second week of November
in Shenzhen. There is enough sponsorship committed including leftover
funds from previous years, but he is asking more EDA vendors for
sponsorship.
Lance reported that there is a possibility of holding the first Taiwan
summit this year. One sponsor has committed so far. Michael Mirmak added
that there have been many requests to hold a summit in Taiwan. There are
many sites in Taipei that could host the meeting. Michael will continue to
press additional contacts for sponsorship. Travel between the mainland
China and Taiwan is now possible directly without going through Hong Kong.
Bob Ross reported that he needs to contact JEITA about a summit in Japan.
Sponsorship opportunities for all upcoming IBIS summits 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 is working on a correlation handbook. The
Quality Task Group checklist and other documentation can be found at:
http://www.eda.org/ibis/quality_wip/
IBIS MODEL REVIEW TASK GROUP
No update.
ADVANCED TECHNOLOGY MODELING TASK GROUP
Arpad Muranyi reported that there was lively discussion this week about the
AMI flow diagrams. There is much discussion on this topic. The clock
times BIRD draft was finalized last week and will be up for a vote next
week. More BIRDs are in the works to clarify text of the AMI
specification. The BIRDs may all be combined into a single BIRD before
submitting to the Open Forum for a vote.
Task group material can be found at:
http://www.eda-stds.org/ibis/macromodel_wip/
INTERCONNECT TASK GROUP
Michael Mirmak reported that the group is meeting Wednesday mornings at 9AM
PT. They are discussing a proposal for binary encoding for Touchstone.
The group plans to discuss other topics for addition to the Touchstone 2.1
revision. Michael will be traveling next week, so Bob Ross will be
chairing the meeting again.
Task group material can be found at:
http://www.eda.org/ibis/adhoc/interconnect/
NEW ISSUES
None.
TSIRD1 – SPARSE MATRIX MAPPING
Bob Ross showed TSIRD1 for final review. This TSIRD proposes an index-pair
mapping solution using two new keywords, [Number of Sparse Labels] and
[Sparse Matrix Mapping]. This solution helps reduce file size by reducing
the size of matrices with symmetries and zero values.
Radek Biernacki noted that all the examples show the [Version] as 2.0, and
this needs to be 2.1. Also, he found one instance where ‘element’ needed
to be pluralized. Bob Ross will make these editorial changes.
Radek motioned for a vote for inclusion of TSIRD1 in the next revision of
the Touchstone specification. The TSIRD vote includes the minor editorial
changes. Michael Mirmak seconded the motion. The vote passed with the
following vote tally:
Agilent: yes
Cadence: yes
Ericsson: abstain
IBM: yes
Intel: yes
IO Methodology: yes
LSI: yes
Mentor: yes
Micron: yes
Nokia Siemens Networks: yes
SiSoft: yes
Teraspeed: yes
A full description of TSIRD1 is found at:
http://www.eda.org/ibis/tsirds/ and
http://www.eda.org/ibis/tsirds/tsird1.0.pdf
TSCHK2 BUG STATUS
No BUGs to report.
IBISCHK5 BUG STATUS
Sergey Nikonchuk and Andrey Babintsev of Freescale submitted BUG115 related
to the new [ISSO_PU] and [ISSO_PD] keywords. There are parser checks
related to these tables. Currents are checked between these tables and the
[Pullup] and [Pulldown] tables. The BUG found that mismatches were checked
for min and max columns of data but not for the typ column. The BUG was
classified as Severe severity, High priority and Open status.
The same people also submitted BUG116. This BUG notes that the Warnings of
mismatches (noted in BUG115) do not give enough significant digits to
determine the severity of the mismatch. This BUG was classified as Severe
severity, Medium priority, and Open status.
Michael Mirmak noted that the titles of the BUGs need to be fixed to
replace ‘{ }’ with ‘[ ]’ characters. Michael also noted that these issues
of tolerances should be added to a parser specification.
IBISCHK5 PROJECT
Bob Ross noted that there are 9 open BUGs right now plus the two BUGs just
added. A new project will be started to fix these BUGs. Bob has drafted a
parser agreement, but it has not been reviewed yet. Michael Mirmak
commented that it would be good for the parser developer to list the parser
assumptions and associated tolerances used in the various parser checks.
Bob noted that we should specify a tolerance for the BUG116 fix.
NEW ISSUES
Michael Mirmak asked if there was a method for reporting a Touchstone BUG.
Bob Ross responded that we have a web page set up for this, but it is not
linked in to the top level site yet.
NEXT MEETING
The European IBIS Summit will be held May 12, 2010 in conjunction with the
SPI conference. No teleconference will be available. The next IBIS Open
Forum teleconference will be held May 21, 2010 from 8:00 to 10:00 AM US
Pacific Standard Time.
