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

AR Review:

- no ARs

New items:

- Roy emailed the group about updates to his "Correlation of Models
  Simulations And Measurement" presentation
  - There was some discussion of where Roy's presentation might be presented.
  - Bob suggested that Roy may need to reduce the length.

Continued review of IQ specification:

- 3.1.4. {LEVEL 3}  [Package] parasitics are validated against data sheet
  - Kim: asking to validate against the model is circular if this is the model
  - Bob: what is the reader supposed to do with this?
  - Bob: it's like [Ramp], not used if better data present
  - Bob: wants [Package] to cover all pins
    column by column
    - Kim: don't use power/ground pins for max [Package]
      - difficult to get actual power parasistics
      - multi-port analysis is required for these complex structures
  - Moshiul: level 2 check so don't need power/ground
  - Kim: Remove this check alltoger, add language to 3.1.2
  - Kim, David, and Moshiul do not include power/ground pins in [Package]
  - We voted to remove 3.1.4 and add language to 3.1.2
    - It should be descriptive, not prescriptive.

AR: Kim write new language adding 3.1.4 recommendations to 3.1.2
AR: Mike update spec with Kim's input, remove 3.1.4

- 3.2.1. {LEVEL 2}  [Pin] section complete
  - Bob: Some analog pins can be stubbed as terminators
    - 555 timer has a capacitor pin, for example
    - make this a terminator
  - Roy: IBIS is a means of data exchange
    - We should not make assumptions about how it is used
    - Roy has analyzed crystal pins described in IBIS
  - Kim:
    - It is beyond our scope to prescribe in much detail how to treat these.

AR: Mike update 3.2.1 to be less prescriptive for analog pins.
