Agenda
======

1) Opens
2) Call for any related patent disclosures
3) Review of ARs:


Arpad:  Submit BIRD 123.3 to the IBIS Open Forum
         - done

Bob:  Propose a simpler way for addressing the needs of parameter
      passing under [External Model] and [External Circuit]
      - not done

Arpad:  Write a new revision of BIRD 117 and 118 to generalize
        references to parameters in files (.ami or any)
        - in progress

Any other AR-s?


Old ARs:

Arpad:  Review the documentation (annotation) in the macro libraries.
        - deferred until a demand arises or we have nothing else to do


4)  Try to answer the questions raised by the Editorial Committee on
    clock_times
    - if clock_times are supposed to be monotonically increasing,
      are repeated "-1" violating this requirement?  (No, because
      the first "-1" is the end of the vector).
    - what is the Rx model supposed to do when its CDR goes out of
      lock?  (Write values which are at a different frequency).
    - are good values allowed after a bunch of "-1" values, as if
      the CDR goes "stop and go" style?  (No).
    - is the Rx model allowed to skip, i.e. have a large jump in 
      the clock_times value?
    - is the tool supposed to consider the model to be bad if the
      clock_times are outside the 1UI +/-jitter range?  If so, how
      should the tool differentiate between being a bad model and
      going out of lock?


5)  ParameterTreeKeyword_BIRD_draft1                          (Arpad)
    - introducing the new BIRD
    - collect initial feedback


6)  BIRD 121.2 draft2                                        (Walter)
    - Walter updated the BIRD (removed all references to the .report
      file)
    - but we still need a formal motion to continue the discussions...


7)  BIRD 150, dependency table                               (Walter)
    - questions/comments/discussion?


8)  BIRD 117.4/118.3 draft3                                   (Arpad)
    - eliminate 120 character line requirement inside these keywords?
    - use virtual file name instead of tree name?
    - should we allow referencing a different .ami file from these
      analog parameter assignments from the .ami file defined in the
      [Algorithmic Model] keyword?
    - separate the general tree syntax rules from context specific
      rules which apply only to AMI or *-AMS and ISS models
    - define the rules for the various parameter types for this
      context (for [External Model], [External Circuit] parameters)
      - Reserved vs. Model_Specific?
      - required vs. optional
    - questions/comments/discussion?


9)  BIRD 116 and BIRD 122                            (Arpad & Walter)
    - questions/comments/discussion?


10) BIRD 125 package modeling                                 (Arpad)


11) New BIRD draft on Naming Rules                           (Walter)
    - questions/comments/discussion?


12) Info, Out, InOut BIRD                                     (Arpad)
    - latest wording includes "in order to be compliant with this
      specification, Model_Specific parameters ... must not ...",
      and omits the word "simulation" so it's meaning doesn't have
      to be defined
    - questions/comments/discussion?


13) Eye Mask definition                                       (Arpad)
    - Rx_Receiver_Sensitivity is the equivalent of the vertical
      (or voltage) part of an eye mask.  It would make sense to
      define the horizontal (timing) portion of the eye mask also.
    - questions/comments/discussion?


14) What is the purpose of the specification?  Describe the syntax
    and rules of the syntax, or tell the reader how to make models?
    - questions/comments/discussion?


Tabled topics:
==============

    - BIRD 144.3 Direct S-parameters under [External Model]   (Cadence)

    - BIRD 145.2 Cascading [Model] with [External Model]      (Cadence)

    - BIRD 121.1, data management parameters (file support)    (Walter)


Tabled AR-s:
============

Ambrish update BIRD 145 for pad to pin mapping and other clarifications
  - Need to say what it will not solve
  - tabled


Thanks,

Arpad
