RE: [sv-ec] Query on transition match

What apparently happened in 1777 is that there were several versions of
the proposal. The original version did not change this text. Version
1800 18-4-1 update proposal_b.htm
<http://www.eda.org/mantis/file_download.php?file_id=1899&type=bug>  and
the following versions did change this text, but the changes were not
colored, and nobody, including the editor, noticed that this text is not
the original and needs to be colored. In the final proposal, the text is
 
"the above sequence causes transition bin b2 to be incremented on the
8th sample (3 nonconsecutive twos), and transition b3 to be incremented
on the 6th sample (3 nonconsecutive threes).  Likewise, transition bin
b2 is incremented on the 10th sample, and transition bin b3 is
incremented on the 9th and 11th samples. Transition bin b5 is
incremented on the 15th, 16th, 17th, and 18th samples.  Transition bin
b6 is incremented on the 12th sample.  Transition bin b7 is incremented
on the 13th sample."

Since the proposal does contain the intended text, and the only problem
was not that it was not colored, I think this can be dealt with purely
editorially, by putting the issue in the Editor state, and adding a bug
note stating the corrections needed.

Thanks,

Shalom

	Swapnajit --
	
	I think you are correct that something went wrong here.  Mantis
1777 changed the sequence of sampled values, without -- as far as I can
tell -- altering text about bins b2 and b3.  The behavior of bins b2 and
b3 used to be straightforward because the sampled values 3 and 2
alternated, and I think that behavior would change with the new sampled
values.  Take a look at Draft 4 (or the 2005 standard) if you want to
see how it was before.
	
	Important note: I can't open any of the HTML attachments to
Mantis 1777, including the final proposal.  I can open the PDF
attachment of an earlier proposal.  The modifications were introduced in
Draft 5, so you can infer the approved proposal from the results.  The
Mantis proposal was written by Don Mills.
	
	I think a new Mantis is necessary to clean this up.  Will
Cadence be filing one?

		Actually, this should be "b3" instead of "b2" and
"threes" instead of "twos". Also its not clear how b3
