-----------------------MINUTES ---------------------------
Mike LaBonte conducted the meeting.

Call for patent disclosure:

- No one declared a patent.

AR Review:

- Moshiul add to 5.2.16
  - Done

- Mike mark 5.2.17 for deletion
  - Done

- Mike mark IQ 5.3.3 for deletion
  - Done

- Mike unswap "S" & "M" in 5.3.17
  - Done

- Mike will send link to Arpad's presentation on waveforms for diff pairs
  - Done

- David produce response to JEITA
  - TBD

New items:

- Mike said there are enough changes to warrant posting a 1.1y IQ spec

- Moshiul sent files showing Micron's IQ-based quality process:
  - In the first figure in the PDF:
    Blue lines correspond to JEDEC requirements

- Review of new text for 5.2.16 provided by Moshiul:
  - Bob: excluding D_overshoot* is a more severe check
    - D_overshoot* provides a relaxation of rules
  - Kim: SiSoft put a high value on these parameters
  - Mike: Is there a convention for translating area to shape?
    - Bob: JEDEC has a triangle picture
      - David: surprising, that shape gives maximum time span for area
    - Offered as an alternative to integration during simulation
  - BIRD 103 allows for:
    - Separate high and low side overshoot limits
    - Maximum amplitude
    - Maximum area
  - Mike: Can we delete this check entirely?
    - Bob: SiSoft felt that all IBIS features should be used
  - Kim: Now the IQ group has semi-conductor representation:
    - Moshiul: It is too difficult to get D_overshoot* data
    - David: Agreed
  - Mike: We could have a "square box" limit check for 5.2.16
  - David: Should comment the assumed waveshape if given
  - Kim motioned to delete 5.2.16 completely
    - No one seconded the motion
  - Moshiul: We could address this when BIRD 103 is approved
    - This would alleviate concerns about D_overshoot* param applicability
    - Bob: It will be at least a year before the BIRD is in effect
  - Bob: Concerned about "docking" good models
    - Maybe "must" is too strong, "should" might be better
  - Mike motioned to change to:
    "If D_overshoot_high, D_overshoot_low, and D_overshoot_time subparameters
    are based on area limit specifications in the datasheet, then the basis
    for the chosen voltage and time limits must be documented in the file."
    - David seconded the motion
    - Bob and Kim agreed
    - The proposal passed

AR: Mike change text of 5.2.16 to require basis documentation
AR: Mike post 1.1y version of IQ specification, with latest edits
