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 11-12 AM EST (8-9 AM PST) Phone: 1.877.384.0543 or 1.800.743.7560 Passcode: 90437837 Meeting ended at 12:05 PM Eastern Time.
