-----------------------MINUTES ---------------------------
Mike LaBonte conducted the meeting.
AR Review:
- Moshiul send DDR2 JEDEC spec
- This was sent May 29
New items:
- Discussion of recent IBIS summit:
- Mike, Bob, and David felt that it went well.
- David expected to see more people.
- Lance Wang had asked why the ibischk -caution option is needed
- The concern would be for large numbers of caution messages.
- Kim felt there might be an option to suppress the messages,
instead of an option to show them.
- Moshiul said that many people use VisualIBIS, and may not
see the caution messages if it does not use the option.
- Mike suggested that categorizing would be good
- Should be able to suppress classes of messages
- Print all errors first, then warnings, etc.
- Bob said the next parser release would be soon
- We would have to act quickly if we want to suggest a change.
- After that the next release might be next year
- Mike wondered if VisualIBIS might have plans to use the option
- Most members felt the option should not be needed, none objecting.
AR: Bob contact Steve Kaufer about their plans for the -caution flag
AR: Bob work with IBIS committee to make ibischk cautions show by default
- Proposal from Agilent to making the golden parser more friendly
- Bob explained that the parser was not originally designed to be
a product front end.
- Example: strings.h is generic
- Mike thought the original request to the IQ group was to provide
a place for documents, not a discussion forum.
- Bob understood it to be for discussion.
- Mike suggested that maybe there should be a separate ad-hoc group
to discuss parser code issues
- Only 2 IQ members have the source code
- No EDA vendors participating regularly
- Mike will contact Michael Mirmak
AR: Mike contact Michael Mirmak to discuss parser code issues
- Mike was contacted by Takeshi Watanabe, representing JEITA
- The JEITA EDA working group has been reviewing the IQ spec
- They will provide their comments to us by the end of August
- JEITA wants to promote IQ use among member IC suppliers
Continued review of IQ specification:
3.3.4. {LEVEL 3} [Diff Pin] referenced pin models matched
- We would want this check passing to simulate for waveforms
- We agreed to change this to level 2
AR: Mike change 3.3.4 to level 2
3.4.1. {LEVEL 2} [Model Selector] referenced [Model]s exist
- Ibischk catches this
- We agreed to delete this check
AR: Mike delete 3.4.1
3.4.2. {LEVEL 2} [Model Selector] first [Model] is default
- Mike said the original IBIS specification had no such requirement,
and EDA vendors assumed the practice ad-hoc.
- Moshiul read the portion of the current IBIS specification that
does now specify this.
- It is not possible for ibischk to check this.
- Roy suggested the check could be deleted
- Mike suggested we could have 2 checks:
- Dependencies between [Model Selector]s must be documented
- Usage notes for [Model Selector] must be documented
- Mike has found IBIS files with [Model Selector], but indication
in the IBIS file or part datasheet how they would be used.
- Bob felt that comments on the [Model Selector] entry lines are best
- Mike agreed that comments in the [Notes] section might become out
of sync with the [Model Selector] sections
- But [Notes] should at least say that there are [Model Selectors]
AR: Mike write a check about dependencies between [Model Selector]s
AR: Moshiul write a check about documentation of [Model Selector]s
Next meeting:
19 Jun 2007
