Agenda
======

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


Arpad:  Modify 10/20/2009 flow (4A) so that it does include the
        "Use Init Output" Booleans
        - in progress

Arpad:  Write a clarification BIRD to discuss accuracy issues
        related to the various AMI clock_tick algorithms in an
        IBIS-AMI DLL
        - not done yet

Todd: Update the BIRD for IBIS S-parameter box based on
      feedback from discussion
        - not done yet

Any other AR-s?


Old ARs:

- Arpad:  Write parameter passing syntax proposal (BIRD draft)
          for *-AMS models in IBIS that is consistent with the
          parameter passing syntax of the AMI models
          - not done

- TBD:    Propose a parameter passing syntax for the SPICE
          [External ...] also?

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


4) Discuss Brad's Connectivity Protocol suggestions


5) Discuss AMI related questions from Mentor

a) Should each GetWave call be required to contain an integer multiple
   of samples per bit (integer number of bit intervals)?
   - Mentor's preference:  yes

b) Is there a requirement to use 2^N samples per bit?  Some models do
   have such "preference", and we don't know how to find out that such
   a requirement exists in the model from its .ami file.
   - Mentor's preference:  no

c) How many clock ticks are expected to be returned by a GetWave call?
   (Number of bits, or number of samples).  Need to know since EDA tool
   needs to allocate the memory for the clock ticks.
   - Mentor's preference:  equal to number of bits in the call, possibly
                           with one extra tick 

d) Is the GetWave call size allowed to vary between calls?  Both getting
   larger or smaller?

e) Are the clock ticks returned by GetWave expected to be aligned with
   sample times, or can they be anywhere in time?
   - Mentor's preference:  no (otherwise, ticks could be made of type
    'integer')


6) Verify final flow for the 5.1 specification



Thanks,

Arpad
