Walter,

After reading your comments, I'm more satisfied with the document. Otherwise 
it's hard to understand some things.
Still, I have a few remaining suggestions, shown in a few additional comments.

Arpad,

I am including my response to Vladimir's comments in the enclosed document. I 
stand by my earlier statement that I believe the current specification defines 
each parameter mathematically precisely and indicates how the parameters are to 
be used in either the statistical or time domain simulations. I would not 
object to adding additional words would be helpful to explain the precise 
mathematical definitions with "C" code or other standard statistical  function 
definitions.

Walter,

Did you look at the comments Vladimir inserted in the
attached Word document?  I think addressing those would
be a good start in this discussion.  But there are some
specifics even in the body of the email from Vladimir:

"The Bird does not seem to be logically complete (does not cover all cases, 
such as Time domain and Statistical flow), or does not provide all necessary 
parameters affecting the results (such as either giving frequency content of Tx 
Gaussian jitter, or making it defined as white uncorrelated jitter, etc.) "

Thanks,

Arpad

Arpad, Vladimir,

There was great effort to define each of the parameters in strict mathematical 
terms. Please indicate specific parameters that the BIRD does not either define 
mathematically precisely, or indicate how the parameters are to be used in 
either the statistical or time domain simulations.

Walter,

Here is the email (with attachment) I mentioned in the
ATM meeting today.  There was no response to it since
I posted it.  I think it would be good to get some
discussion going on these questions/comments.

Thanks,

Arpad

Walter and All,

I am forwarding Vladimir's comments on BIRD 123.2.2 to this
list for discussion.  Please look at his comments which are
in the attached Word document.  Since Vladimir is also on
this email list, please direct your answers, questions and
comments to him.  (I don't want to be the middle man in such
conversations...).

The general problem is ambiguity of given definitions when it comes to 
implementation in EDA tool.
The Bird does not seem to be logically complete (does not cover all cases, such 
as Time domain and Statistical flow), or does not provide all necessary 
parameters affecting the results (such as either giving frequency content of Tx 
Gaussian jitter, or making it defined as white uncorrelated jitter, etc.)

Thanks,

Arpad
