BIRD189.5_draft18_v8 Review:
Michael stated on page 30 the "Important" notes we reviewed in ATM and need to
be changed. Michael asked Arpad Muranyi what the latest text that should be
used is. Arpad stated he made some small changes in an email and would like to
discuss combining the two notes. Arpad questioned the word "incorrect" and
suggested to add the word "may" after potentially. Mike thought that the
phrase "potentially may" sounded redundant. Arpad said he is okay with how the
text is written now. Arpad stated that the word "incorrect" is not
appropriate. Mike suggested the word "unexpected". Michael thought it can be
reviewed as part of the editorial pass. Walter Katz suggested the word
"different". Walter moved to change the word "incorrect" to "different". Bob
seconded the motion. Michael was concerned that it is different from what.
Walter stated that you are not accounting for all the currents, so you will get
different results. Walter withdrew the motion.
Mike noted in regards to merging the "Important" note paragraphs, the second
paragraph is different, since it mentions TS4_File. Michael asked if there is
anything wrong with the sentence. Arpad replied that this sentence is telling
model makers to pay special attention to the Terminal_type. Walter stated the
model maker should pay attention to all of the terminals. Mike commented that
this warning implies that there is a certain mistake to avoid, and it is not
clear to him from the text what that mistake is.
Walter moved to remove the second "Important" note paragraph. Bob seconded the
motion. Arpad objected to the motion.
The roll call vote tally was:
Intel - Abstain
Mentor - No
Micron - Yes
SiSoft - Yes
TeraSpeed - Yes
The roll call vote concluded with a tally of Yes – 3, No – 1, Abstain – 1. The
motion passed.
Randy Wolff commented that he agreed with Mike's statement about it not being
clear what mistake is to be avoided with Arpad's warning text.
Michael noted there are several comments associated with the section of
"Important" notes that have been replaced. The first two comments have been
resolved. And, the third comment now has the necessary language changes in the
new note.
Michael stated there are some remaining comments associated with deleted
sections that can now be removed.
Michael commented the only remaining issue is the rail rule relaxation. Bob
would like to propose to keep the rail rule changes. Walter would like to
remove this text. Arpad stated he is not necessarily opposed to the rules, but
there is significant work to do on the wording. He would like to see a version
of the BIRD without the rail rule changes. He stated this is another topic
that could take time to discuss. Bob asked if the intent is to keep the rail
rule changes in BIRD189.5 or to put the changes in as a BIRD189.6. Arpad would
like to have a clean copy without the rail rule changes. Walter agreed that we
could come up with a clean version of the document, and Bob can change that
document. Michael clarified that the proposal would be to submit BIRD189.5
without the rail rule changes, and a BIRD189.6 with the changes could come
later. Bob stated he prefers to not go that route, but he would accept it.
Michael asked if there is a formal motion to do this. Arpad moved to submit
the draft of BIRD189.5 without the rail rule relaxations. Walter seconded the
motion. Randy agreed with this approach. Bob said he would be okay with this,
but he would oppose BIRD189 in the Open Forum without the rail rule changes.
There were no objections.
Bob asked who should do the changes. Michael asked what should be removed and
added back in. Bob noted the changes are marked in red, including the red
strike through where text was deleted. Mike noted we do have a previous
version without the changes, but it may be missing some editorial changes and
the "Important" note changes. Walter suggested for Michael to make the edits
live.
Michael went through the document and backed out the rail rules changes that
Bob made in red. Bob stated on page 9, he would like keep to the words "as a"
before Buffer_Rail. He noted that we are mixing two concepts in this
sentence. Walter agreed with keeping this in.
On page 24, Bob had removed the word "token", as it is not used anywhere else
in BIRD189. Michael agreed with deletion.
On page 31, Bob suggested to keep the phrase "referenced through Interconnect
Model Set(s)", which he had added.
Michael asked if we are ready to submit this. He also asked if there is
anything in the History section that needs to be added. Bob stated he is okay
with submitting. Walter asked if we should accept all changes before
submitting. Mike stated he will do a document compare between BIRD189.4 and
BIRD189.5 to reflect those changes in the markup before posting.
Michael will send out the BIRD189.5_draft18_v8, and unless any objections are
submitted over email, he will send BIRD189.5 as a formal submission on Friday
[AR].
Arpad asked if this needs to be taken up in ATM next week. Michael stated he
does not see any need to discuss BIRD189, but he cannot comment on BIRD158.
Walter stated he has a schematic picture that he would like to discuss in ATM.
Next Meeting:
The next meeting will be April 25.
Mike moved to adjourn. Randy seconded. The meeting adjourned without
objection.
