Hi Arpad,

Sorry for a delayed reply. I would suggest expanding the text to cover the 
following issues:


(a)    description of how the "Reserved Parameters" and "Model Specific" names 
are to be not included: if a name is not included does it mean that the 
corresponding pair of parentheses is also removed (I think so - but we need to 
say so). Perhaps we could define it as "branch collapsing"),

(b)   the opening sentence seems to cover both the "_in" and the "_out" 
strings, yet in Item 3 the parameters of Usage Out are excluded; perhaps we can 
cover each case separately,

(c)    we need to say whether all "In" and "InOut" parameters in the case of 
the "_in" string, and all "InOut" and "Out" in the case of the "_out" string 
shall be included, and whether the order shall be consistent with the AMI file,

(d)   we need to say whether the DLL shall gracefully ignore any other 
parameter whose name may or may even not be in the AMI file (if so, we do not 
need to say that parameters other than (c) need to be omitted,

(e)   for Item 4 we need to define the process of making branches to become 
leaves,

(f)     we need to precisely define Value (and Default) for parameters whose 
format requires more than one number to constitute a value, or we may coin 
another terms such as "composite value".

Hello AMI Experts,

This thread stopped a day or so ago without reaching a conclusion.
I am going to summarize the questions I would like to get answered.



1)  When does a branch become an "AMI parameter"?  Does this have
to be spelled out in the IBIS-ATM specification, or does this belong
to a Cookbook or HOWTO document?

Currently this is what I have in the Typos BIRD draft:

|*              A branch in the .ami file is an "AMI Parameter" if it
|*              contains the leaves Type, Usage, and any of the following
|*              leaves:
|*
|*                   Default
|*                   <data_format> or Format <data_format>
|*
|*              and does not contain another branch.  A branch which
|*              contains one or more sub-branches may only contain the
|*              Description <string> leaf/value pair in addition to the
|*              sub-branches.



2)  What is supposed to be passed into the AMI executable model in the
parameter string, and what is supposed to be omitted from this string?
Does this have to be spelled out in the IBIS-ATM specification, or does
this belong to a Cookbook or HOWTO document?

Currently this is what I have in the Typos BIRD draft:

********************************************************************************
REMOVE THIS PARAGRAPH if the next few are agreed on:****************************
|*              The tree data structure passed in and out of the DLL
|*              described in section 3.1.2.6 of Section 10 of this document
|*              is similar to the tree data structure in the .ami file except
|*              the 'Reserved_Parameters' and 'Model_Specific' branch names are
|*              not included, the "AMI Parameter" branches become leaves and
|*              the "AMI parameters" of Usage Info and Out are not included.
END OF REMOVED PARAGRAPH********************************************************
********************************************************************************
|*
|*              The parameter string passed in and out of the DLL (described in
|*              section 3.1.2.6 of Section 10 of this document) is formatted
|*              the same way as the tree data structure in the .ami file with
|*              the following exceptions:
|*
|*                1) The "Reserved_Parameters" and "Model_Specific" branch
|*                   names are not included
|*                2) None of the Description leaf/value pairs are included
|*                3) AMI Parameter branches or sub branches with Usage Info
|*                   or Usage Out are omitted, but all other branches or sub
|*                   branches are included
|*                4) AMI Parameter branches with Usage In or Usage InOut
|*                   become leaves
|*



3)      Define how/where the DLL returns Out or InOut parameters and
how/where the EDA tool is supposed to look for these values.  Does
this have to be spelled out in the IBIS-ATM specification, or does
this belong to a Cookbook or HOWTO document?

There is nothing on this topic in the Typos BIRD draft, nor can I
find anything about this in the current IBIS specification.

Thanks,

Arpad
