No opens were raised. No patents were announced. Walter Katz noted that the
phase the Task Group is engaged in is called "Comment Resolution" for the IEEE;
each comment is assigned a number and then voted on.
Michael Mirmak announced that Draft 3 of the IBIS 6.1 document has been posted
and would be reviewed during the meeting. Walter noted that he had provided
some changes via e-mail. Bob Ross also stated he had a list as well. The new
draft includes BIRD175.3, BIRD176, and BIRD177. Michael added that the new
Reserved Parameters in BIRD175.3 have not yet been added to the parameter
tables in the AMI section. Mike LaBonte asked whether a new "Modulation"
section might be needed, similar to Clock and Jitter parameters.
Changes noted in the meeting include:
* Change page 9 from "9 BIRDs" to "12 BIRDs". (Randy Wolff)
* Add [Initial Delay] to the hierarchy under [Submodel], after [Falling
Waveform]. Add [Merged Pins] to [Define Package Model] and .pkg (Bob, Randy).
* For [Initial Delay], use brackets for keywords when used as keywords
(Michael)
* Spacing issues under [Merged Pins] (Bob)
* All the PAM4 parameters need Required/Optional "and illegal
before..." language.
* Extraneous bullets showed up in the PAM4 section (Mike, Walter)
Randy noted that the page headers jump from left to right, book style. This
appears deliberate.
There was some discussion regarding Table 15 and "otherwise illegal" phrasing
for Resistance Matrix. This was removed.
Bob suggested that, for Section 10, we should refer to "AMI_Version 6.1", not
"IBIS 6.1". Arpad asked whether this should this be "v6.1". Mike suggested
the document refer to "IBIS 6.1" per the rules for IBIS Version.
Mike asked whether the document consistently has mid-keyword underscores
removed and replaced with spaces.
Michael noted that "SERDES" and "SerDes" are used interchangeably. Mike
suggested the industry mostly uses "SerDes". Michael suggested that the
entire PAM4 opening paragraph should be moved from Section 10.1 to later in the
document. Radek agreed, except that the first two sentences could remain in
10.1.
Mike asked whether the phrase "logic levels" is used correctly in the document.
Walter suggested that it is correct; we also use "symbol". Mike mentioned
that the team had discussed but not ratified including a glossary. A search
for "logic levels" in the document is suggested.
For the next meeting, the team will review an new draft that will include
updated tables for Reserved Parameters and address the other changes noted
above.
