Ken,

I would like to make a comment on slide 3 of the presentation
you gave us in the ATM teleconference a week ago and the
discussion that followed.

If I understood the discussion correctly, you and Kumar are
concerned that one model could produce different results
when only its Init functions are used vs. when its GetWave
functions are also used.  The discussion between you and Todd
ended in a disagreement.

However, it just occurred to me that the AMI portion of the
IBIS 5.0 specification already talks about the possibility
of having two types of analysis paths, one that only uses
the Init functions (for LTI systems), and another that also
involves the GetWave function when non-LTI effects are present.
This is found in Section 10, 2.1 and 2.2 in the specification.

Doesn't this close the discussion we had in the meeting when
you were presenting in a sense that you are challenging an
intent that is already clearly spelled out in the specification?

Thanks,

Arpad
