1) With recorded data and the possibility for
post processing I don't see any violation
of causality.
2) The user can only ask the EDA tool to do
something if the EDA tool has a certain feature
implemented. Since the meaning of Model_Specific
parameters are not defined, I would think the
EDA vendors will have a pretty hard time to
figure out what features to implement.

Arpad,
Several comments on the following:
Model_Specific parameters must not be used for purposes which may alter
past, present or future simulation results in any way. In case there is
a
need to use parameters of (Usage Out) or (Usage InOut) for such
purposes,
those parameters shall be defined as Reserved_Parameters and fully
described in the specification.
First, "alter past" violates causality.
Second, in my e-mail " The roll of IBIS, Model Maker, EDA Tool, and
Model
User" sent Sat 4/9/2011 1:43 PM I avowed that "The User decides how he
wants the outputs of the model to be used." So if a User asked an EDA
tool
to alter the results of a simulation based on any output of any model
(including, but not limited to AMI models), how can IBIS prevent this.
Therefore this statement cannot stand.
Walter

Agenda
======
1) Opens
2) Call for any related patent disclosures
3) Review of ARs:
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) Cross talk BIRD draft
- any last minute comments?
- vote to submit it to the IBIS Open Forum
5) Out_InOut BIRD draft
- discussion
- schedule a vote
6) (Format) Table Syntax Clarification (Row 21, 22)
from Ambrish, Walter and Bob
- last week we decided to accept Bob's suggestions from these:
- Table_BIRD_Ambrish_02.pdf (Ambrish)
- Table_BIRD_Walter_05.pdf (Walter)
- Table_BIRD_Bob_proposal_02.pdf (Bob)
7a) BIRD 123.2, jitter parameters (includes Row 37)
- review latest changes (additions) from Walter
- do the 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?
7b) BIRD 121, data management parameters (file support)
- questions, comments?
7c) BIRD 124, dependency table
- questions, comments?
8) Analog BIRD draft (Walter)
- questions, comments?
9) Backchannel BIRD draft (Ken)
- questions, comments?
10) IBIS-AMI Section 6c Tables Update (Table1_3_BIRD_draft_1.pdf)
- this is on hold until all related items are defined
11) Define relationship between Type and Format (Row 25 in Task List
Type_Format_Table_BIRD_02.pdf)
- this is on hold until all related items are defined
Remaining Task List items:
==========================
Row 18: What is the ambiguity between Format and Text Strings?
- answer: See row 25
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
- discuss Walter's suggestions
Row 26: This is basically the same as the items in Row 46-47.
Row 33: Is AMI_Init restricted to change first column of impulse_matrix
only?
- Sigrity is writing a BIRD draft on this (Ken)
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
Thanks,
Arpad
