Mike,
Thanks for your question!
BIRD 123 is currently in discussion at the committee level. As one of the
authors of the BIRD, my viewpoint is admittedly biased, so I'll leave it
to others to comment on adoption and timetables.
To your second question - one of the goals of the BIRD 123 is to allow IC
vendors to include the jitter parameters as part of their model using a
standard syntax. This is what some IC vendors are already doing with
their proprietary simulators - when you select a particular technology and
model, there are jitter and noise budgets that get automatically included,
whether you realize it or not. The jitter and noise syntax we've proposed
in BIRD 123 allows vendors to provide that same data in IBIS-AMI models.
For what it's worth, there are IBIS-AMI models out there that are already
leveraging this syntax.
Hope that helps,
Todd.

Subject: [SI-LIST] Adding jitter to IBIS-AMI
I have a couple of questions about adding jitter to an IBIS-AMI TX
model...
1. Is BIRD123 likely to be adopted for the next release? Any idea of
the time table?
2. Is the expectation that EDA vendors will add the jitter parameters
or will the IC vendor embedded them in the model?
Thanks, Mike
