Agenda
======
1) Opens
2) Call for any related patent disclosures
3) Review of ARs:
Arpad: Submit the two BIRD drafts which were voted on to the
IBIS Open Forum
- done
Arpad: Send an email to the IBIS-Editorial reflector to start
the editorial process on the correction BIRDs
- done
All: Please send comments to Arpad by email on the topic
of how Corner typ/slow/fast should be associated with
typ/min/max in IBIS
- 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_ParametersOut_BIRD draft (Row 51) (Arpad)
- any final comments, questions on the BIRD draft?
- vote to submit it to the Open Forum
5) IBIS-AMI Section 6c Tables Update (Bob)
(Table1_3_BIRD_draft_1.pdf)
- is this ready for a vote to submit it to the Open Forum?
6) AMI_CornerRange_BIRD draft (Row 54) (Arpad)
- decide what to do about associating typ/slow/fast of
Format Corner with legacy IBIS typ/min/max
- leave it vague?
- rely on a C_comp fix (Bob's BIRD, or similar)?
7a) BIRD 121, data management parameters (file support) (Walter)
- questions, comments?
7b) BIRD 122; Analog Buffer BIRD (Walter)
- replaced with ISS_Buffer_BIRD.doc
7c) 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?
7d) BIRD 124.1, dependency table (Walter)
- questions, comments?
8) Info, Out, InOut BIRD (Arpad)
- changed words to include "in order to be compliant with this
specification, Model_Specific parameters ... must not ..."
- changed wording so that "simulation" is not used so it's
meaning wouldn't have to be defined
- any comments, questions on this draft?
- is this ready for submission to the Open Forum?
9) Backchannel BIRD draft (Walter/Ken)
- questions, comments?
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 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 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 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
