No patents were announced. Michael Mirmak listed the topics for discussion:
inclusion of new BIRDs (including Initial Delay updates); any additional
editorial changes to the 6.1 draft since the last review.
Bob Ross noted as an open that the specification uses "simulator" in 40
locations and "EDA tool" in 176 locations in the document.
Michael asked whether there is any context where these are distinct. Bob
suggested not. Bob and Radek Biernacki stated that "EDA tool" used to be "CAE
tool" in the early to mid-1990s. Michael asked whether the "EDA" acronym was
defined/spelled-out on its first occurrence. Bob replied that this could be
the URL www.eda.org<http://www.eda.org>. Radek suggested that the document
combine "EDA tool" and "simulator" on their first appearance.
Bob noted that BIRD 175.2 has been updated but not yet posted; it should be
included in any 6.1 draft update. Mike LaBonte stated that there is an
immediate need for support, as PAM-4 models are already available in industry.
On BIRD 172.2, Michael noted that there was earlier worry that new BIRDs,
related to interconnect, would modify 172.2 features. Bob suggested that some
of the parameter definition methods could result in ambiguous AMI
files/behavior. Radek added that the concern with 172.2 related to statistical
parameter treatments, which have been deferred in the draft proposal under
consideration by the Interconnect Task Group.
Arpad Muranyi suggested that perhaps BIRD 178 also needed inclusion. Michael
and Randy Wolff responded that there's no immediate need for the directionality
feature, unlike PAM-4. Some additional technical features may be needed in
IBIS to enable bi-directional analysis.
BIRDs 175, 176, and 177 are up for a vote at the June 12 Open Forum meeting;
assuming they are approved, they should be added to the draft. Bob noted that
PAM-4 inclusion may result in a parser cost increase. Mike suggested that the
parser work to support PAM-4 should take a single day of effort.
Michael will update the draft with the three BIRDs, plus the new language
related to "simulator" and "EDA tool".
