Agenda
======
1) Opens
2) Call for any related patent disclosures
3) Review of ARs:
Bob: Check BIRD 127 for type clarification possibilities
- in progress
Ken: Draft language to clarify handling of multiple channels
(cross talk BIRD)
- in progress
Ambrish: Start a BIRD on row 25 in the Task List
- in progress
Bob: Write a BIRD on correcting Table 1-3 in the spec.
(Row 23 in the Task List).
- 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) Cross talk BIRD draft
http://www.vhdl.org/pub/ibis/macromodel_wip/archive/20110301/arpadmurany
i/Crosstalk%20Clarification%20BIRD%20draft%203/Xtalk_BIRD_3.pdf
- no changes have been made to the BIRD draft since last week
- QUESTION: how does the Init function know whether it belongs
to a victim or aggressor Tx? Aggressor Init modifies all
columns in the impulse_matrix, victim Init modifies only the
first column. This can be resolved by the EDA tool passing
a single column impulse_matrix to the victim Init and then
add the modified IR-s from the aggressor Init to this, but
this becomes a flow discussion.
5) (Format) Table (including Row 21, 22)
- Continue discussion from last time
- what is the meaning/purpose of the first column?
- what is the purpose for tables in general?
6) Model_Specific parameters Usage Out/InOut
- Since we do not know the meaning of these, what is
the EDA tool expected to do with them?
- Type Tap has a unique meaning, we could allow this,
but something should be mentioned in the spec on what
the tool is expected to do (plot, log file, etc).
- how about the rest of the Types? Does it make sense
to allow them?
7a) BIRD 121, data management parameters (file support)
- questions, comments?
7b) BIRD 123, jitter parameters
- how do we deal with Usage Out? (includes Row 37)
- remove it from the spec?
- specify that only the Init function can return values?
7c) BIRD 124, dependency table
8) GetWave block size for multiple calls
- does each call have to be the same size?
- does the block size have to be an integer bit size?
9) Anything else for today?
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
- need someone to volunteer to write a BIRD
- Bob agreed to do this after the 2010 Asian Summit
Row 25: Define relationship between Type and Format
- discuss Walter's suggestions
- need someone to volunteer to write a BIRD
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
