Syed,

I can't reply in any more detail than what Jon has already stated, or I'd have
to shoot the reflector. But Jon is right on. It was due to controlled rise
time concerns that we introduced this feature into 2.0, and have found it to
work quite well, though developing an underlying model that consumes the data is
a challenge, as the EDA vendors reading this no doubt know.

Syed,

I believe that the waveform mechanism can handle many forms of the
"gradual turn on" and
the "feed back" drivers. In fact, I believe that is what INTEL wanted
to use these
waveforms for in the first place (so called Rise Time Controlled drivers).

The feed back issue is harder since it depends on the speed of the
feedback mechanism and that
speed is NOT defined (as yet) in the IBIS format.
