Maybe I should have stated the "obvious":
BIRD 160 was written so that the original text in black
is the content of the v5.1 spec, and all changes (in red)
are with respect to the text of the v5.1 spec.
Of course now in BIRD 160.1 there are some changes with
respect to BIRD 160 and it seems that Word doesn't have
the ability (or I don't know how to do it) to track
subsequent changes with different colors to be able to
distinguish between the changes made to the original or
an edited version of the original.
Either way, everything that is black is from the v5.1
specification, and anything that is color (red) is
proposed changes.
I hope this clarifies things...
Thanks,
Arpad

Arpad,
Therefore, the new content isn't 39 pages long. That's what I was after.
Todd.

Todd,
I am not quite sure what you are trying to say with
"standalone" vs. "rewrite of key sections"...
The reason the BIRD is 39 pages long is because I
copied the entire section on [External Model] and
[External Circuit] into the BIRD. I didn't do this
because these sections are completely rewritten, as
you might say. I did this because some of the changes
(such as adding IBIS-ISS to the enumeration of the
languages) are sprinkled out over many pages and I
didn't feel like pointing to page numbers and paragraph
numbers to indicate the locations for where all these
editorial changes are needed. With our new Word format
and it's wonderful color enhanced ability to track
changes I felt that it will be much easier to see what
the proposal does to the original text if I took the
entire sections for these keywords and made the changes
in them with "track changes" turned on. If you just
follow the colored text you will see what the proposed
changes are.
But in short, the BIRD proposes the following:
- add IBIS-ISS as a language to these keywords
- add the ability to assign values to the parameters
of these keywords (this was an AR that was on our
ATM agenda for a few years)
- add the ability to parameterize the D_to_A and
A_to_D converters
- add the polarity argument for D_to_A converters
connected to the D_drive stimulus when used with
true differential models so that the model maker
wouldn't have to implement inverters in their models
I hope this clarifies your question.
Whether we can complete the review and voting of this
BIRD in time for the next IBIS version has yet to be
seen, but I would like to remind you that the BIRDs
(116, 117, 118 and 129) from which BIRD 160 was complied
were submitted about two or more years ago and we have
discussed them in numerous meetings including IBIS
Summits, so the topic should be quite familiar to most
of us by now. For that reason I am quite optimistic
that we can get it ready for the next IBIS version.
Thanks,
Arpad

Arpad,
Sorry to be late to the review party.
Is this document a standalone proposal, or a rewrite of key sections of the
IBIS spec?
This document is 39 pages long, and the whole spec is only 199 pages. I don't
see how we're going to get this vetted and integrated in time for a mid-year
update to IBIS.
Todd.
