Minutes:

- Roll call

-Review of Action Items
* No open action items

- DAC IBIS Summit Review
* Presentation on quality project made by Barry Katz.  There were a
number of papers related to model accuracy and parameter extraction.
Papers are all available at http://www.eda.org/pub/ibis/summits/jun02.

* Open Source IBIS Golden Parser
At the Summit, the general feeling seemed to be against an Open Source
parser, as reported by both Lynne Green and Bob Ross.  However,
member companies are welcome and encouraged to submit fixes; Matt
Flora of HyperLynx (Innoveda/Mentor Graphics) has been recognized for
doing this.  There was also discussion of s2ibis, which is open source
and needs an update.  North Carolina State U did s2ibis2, and is
interested in working on an s2ibis3.  The earlier s2ibis3 project "died"
because it was in conflict with a product produced by an IBIS Committee
member company, which resulted in IBIS not funding the work.
The Quality committee discussed ways to work within the IBIS committee.
The possibilities include creating a PERL tool for data checking, =
augmenting
the parser or PERL tool to check for quality measures (including text).
There is clear potential benefit to both the checklist and a tool to =
check a
model against the checklist.  As this progresses, need to bring ideas to =
the
IBIS committee for further feedback.

- Continue discussion on waveform rules
* Bob Ross has verified that VMEAS was intended for drivers, and is
ambiguous for receivers.  BIRD 62.6 contains the keywords/subparameters
to take care of this.

* There are 10 BIRDS that have passed since IBIS 3.2 was passed in 1999.
There was discussion of whether the IBIS quality checklist should =
include
these.  Since IBIS 4 is expected out ahead of the checklist, it was =
generally
agreed that the IBIS 4 keywords/subparameters should be addressed in the
checklist.  Golden Waveforms and Receiver Thresholds were identified as
key BIRDs.

VIH/VIL was discussed next.  Basic quality check can be made to see if
VIH and VIL are between the Vcc and Vss voltages.  Sources of the values
should be documented (simulation, interface specification, etc.).  =
Checklist
documentation should include how various voltage levels are typically =
used
by EDA tools for timing checks, ringback checks, etc.

It was noted that IBIS 4 parameters may imply new quality levels in the
checklist.

It was suggested that there be a quality summary at the top of the IBIS
file (such as the quality level for each buffer within the file).  =
TABLED to
next meeting.

AR (ALL): Review those accepted 10 BIRDs (62.6 - 73) for discussion at
next meeting.

Next meeting:
Tuesday, July 2, 11 AM EST (8 AM PST).
