Mike LaBonte conducted the meeting.

Call for opens and IBIS related patent disclosures:

- No one declared a patent.

AR Review:

- Mike draft proposal for new IBIS test keyword hierarchy
  - Started, but not complete

New items:

- Anders: Should the inner keywords not be bracketed?
- Anders: Should there be just a name after [External test]?
- Mike: Initial_state is for diff pairs to use one .stim file
- Bob: In IBIS models can take one stimulus for diff pairs
- Mike: We could also have [Test Pins] or [Test Components]
- Anders: Initial_state should be non-inverted or inverted
- Mike: The param should be Inverted = True/False
- Anders: An external file could instantiate buffers from any file
- Mike: This sounds like having the B element
- Moshiul: How does it know which pin RLC to use?
- Moshiul: EBD makes calls to external IBIS files
- Mike: We have not yet discussed providing [Test Data] for EBD
- Bob: We could have an external test for EBD
- Mike: We could define a new file format
  - It would call IBIS and EBD files, plus others
  - Some things like subckts, stimulus and data could be in the same file
  - We would call them by name and make the file parameter optional
- Mike: Should the format be like IBIS or XML?
  - Maybe AMI
- Anders: The external data file might have named sections
- Bob: We might not want a full B element with supplies
- Mike: We would probably want to declare things that are external first
- Bob: We should make a tree diagram
  - If this is too complicated it will not be adopted

AR: Mike update [External Test] proposal based on feedback

Next meetings:
- Next meetings and Mar 01 and Mar 08

Mar 01 agenda:
- Review external test BIRD draft

Meeting ended at 12:01 Eastern Time.
