Agenda
======

1) Opens
   - no meeting next week due to IBIS Summit
   - planning on a short ATM update presentation at the Summit

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


Arpad:  Submit the Table Syntax Clarification BIRD draft to the
        IBIS Open Forum
        - done (BIRD 132)

Arpad:  Update the BNF BIRD draft with comments received from Bob
        - 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)  AMI_BooleanBNF_BIRD draft (Row 55)                    (Arpad)
    - no update for today (need to incorporate Bob's comments)

5)  AMI_CornerRange_BIRD draft (Row 54)                   (Arpad)
    - note:  BIRD 127.1 update (fix example on pg. 147)
    - any comments, questions on the BIRD draft?
    - is this ready for submission to the Open Forum?

6)  AMI_ParametersOut_BIRD draft (Row 51)                 (Arpad)
    - note:  BIRD 127.1 update (fix example on pg. 190)
    - any comments, questions on the BIRD draft?
      - **msg is not allowed for GetWave.  Do we need to say that?
      - do we need to say anything about which functions do
        allocation/deallocation?
    - is this ready for submission to the Open Forum?

7)  AMI_FunctionReturnValue_BIRD draft (Row 61)           (Arpad)
    - is the verbiage on sending feedback to the tool
      and user sufficient, or do we need more specifics
      (msg...)?
    - any comments, questions on the BIRD draft?
    - is this ready for submission to the Open Forum?

8)  Info, Out, InOut BIRD                                 (Walter)
    - what did we conclude from the presentation Walter gave us
      last week describing Compliance, as related to
      Model_Specific parameters?

9)  Out/InOut BIRD draft                                  (Arpad)
    - discussion on the latest revision posted on the 
      ATM website

10) Define relationship between Type and Format (draft 3) (Ambrish)
    (Row 25 in Task List)
    - introduction to the new version


11a) BIRD 121, data management parameters (file support)  (Walter)
     - questions, comments?

11b) BIRD 122; Analog Buffer BIRD                         (Walter)
     - replaced with ISS_Buffer_BIRD.doc

11c) BIRD 123.2.2, jitter parameters  (includes Row 37)   (Walter)
     - review latest changes and graphics
     - do these changes answer the questions raised before:
       - remove Usage Out from the BIRD?  or
       - specify which function (Init or GetWave) can return values?
       - specify what the EDA tool should do with the returned values?

11d) BIRD 124.1, dependency table                         (Walter)
     - questions, comments?



12)  Backchannel BIRD draft                               (Walter/Ken)
     - questions, comments?



13)  IBIS-AMI Section 6c Tables Update (Table1_3_BIRD_draft_1.pdf)
     - this is on hold until all related items are defined




Remaining Task List items:
==========================

Row 21: According to the BNF, the Format = Table syntax is invalid.
        - If Format is removed, this s not a problem, but if Format
          is there the problem still exists.  Do we need to fix this?
          - we will address this when talking about Table

Row 22: The syntax for a leaf is:
        (Row 22 in Task List)
           <leaf>:   ( <parameter name> whitespace <value list> )
           So in a Table which is written like this:   (-50 -0.1 1e-35),
           -50 is actually a parameter name, i.e. a string, not a value.
        -deprecate Table back to List?
        - we will address this when talking about Table

Row 23/24: Fix the two tables to reflect what is in the text
           - Bob started a BIRD draft which will be finalized
             as other BIRDs are completed

Row 25: Define relationship between Type and Format
        - Ambrish started a BIRD draft which will be finalized
          as other BIRDs are completed

Row 35: Clarify questions about impulse response
        - this needs to be discussed

Row 37: Usage Out for reserved (jitter) parameters
        - which function (Init or GetWave) can return these?

Row 46/47: Remove certain parameters and keywords
           - this needs to be discussed

Row 51:  AMI_parameters_out
- optional for AMI_GetWave only?
- specify that if not returned the pointer should be a valid NULL
pointer
- do the same for AMI_parameters_in (NULL pointer)

Row 52:  What should the tool do without clock times?
        (postponed)
- need to specify how the tool should sample the waveform
- address other SERDES protocols which use external clocking

Row 53:  Labels BIRD draft from Walter?
        (postponed)

Row 54:  Format Corner and Range interpretation
- spell out what makes the selection for Corner and Range
- is it the tool's corner setting?
- if so, how does typ/min/max align with typ/slow/fast for Corner?
- is it supposed to be shown in a GUI for the user to make a selection?

Row 55:  Add Boolean to the BNF

Row 56:  Should (Usage Out) parameters have Default or a Value at all?

Row 57:  Existing Reserved_Parameters of (Usage Out) need
definition for which function returns them (Init or GetWave)
         (postponed)

Row 58:  Model_Specific parameters should not be (Usage Out)
or (Usage InOut)
         (postponed)

Row 59:  Make sure Table 1 on pg. 148 doesn't show
         Ignore_Bits as Out
         (this is just a reminder for Row 23)

Row 60:  Clarify what kinds of failures should result in
"0" in the function's return value (Section 3.1.3 and 3.3.3)
- function call failure
- model cannot operate properly (CDR getting out of lock)

Row 61:  Are the **AMI_parameters_out arguments of AMI_Init
and AMI_GetWave the same or different memory locations?
- if it is the same, this is inconsistent with **msg
- if not the same, **msg should only be available to AMI_Init...

Row 62:  Clarify the **msg argument
- who allocates/deallocates its memory (DLL)?
- IF it is the DLL, it is allocated in AMI_Init.
  Will this be available to AMI_GetWave too?

Row 63:  Should AMI_Close always be required?
- should the spec say that all memory deallocations
  are done in AMI_Close?
- is that possible? (What if AMI_Init or GetWave
  allocates memory that is not visible to AMI_close)?
- Currently AMI_Close is not required with AMI_Init,
  therefore when AMI_Close is not present AMI_Init
  has to do memory deallocations also...
- goal is to make the model maker's life easier,
  and this is kind of confusing...


Thanks,

Arpad
