RE: [IBIS Ver] Keyword's argument

I tend to agree with Jon. There may even be slight variations
in the spec which may be invalid in the "official" (1.1, 2.1
and 3.2) versions.

I actually disagree with this.
While it is true that you could put any version number on a model, since the
spec
was changing (and being corrected) a lot, especially in the 3.x range, it is
possible, and even likely that a 3.1 or 3.0 model would not be supported by
EDA
simulators. If you are looking for good EDA support, you should release
models in
the 2.1 or 3.2 levels only since they are the only "sanctioned standards".

Now, this is my opinion, but I bet a buck it is a safer assumption than
releasing
pre-standard level 3 models. For instance, I have seen legal 3.0 models that
can
be legally parsed so as to generate two completely different models. We
fixed
this in 3.2
