Hi, Peter,
Your question is valid for published specifications. However, this is
still a DRAFT spec (with
major revisions over the past 5 years). An updated draft is expected to
be released to the
IBIS Open Forum sometime in April.
Historically, EDA support for IBIS features has depended on several
things:
* A specification approved in an IBIS Open Forum vote
* Publicly available parser executable
* Vendor models using those features (and that pass the parser)
* What Marketing calls "customer demand" (i.e. people using those vendor
models).
By definition, none of those things exists for a draft spec. (Since you
brought it up, there is
not yet a parser for IBIS 4.0.)
Now is a good time to let your favorite vendor know if you plan to use
IBIS Interconnect
models. This gives the tool makers a "heads-up". Also, as Sudheer
pointed out, people
might not use the new format if vendors or tools support alternate
models.
Best regards,
Lynne

I think the question about which vendors support of ibis features is
valid. Maybe it should be phrased as "Does any vendor's softward support
this?" or "Does any software vendor plan to support these connector
models".
New ibis specs and features are being added, however the software
programs that I have used still do not even support all of the features
in the IBIS 3.2 Specification, and we are at IBIS 4... Users of IBIS
models and IC vendors need to know this information since IBIS models
can be very time consuming and difficult to create. It can certainly be
a waste of time if all of the software that is available is still only
IBIS 2.1 compatible.
Regards,
Peter
