Sanchayan,

As Lynne pointed out, the V-t tables of the IBIS files
are used to describe the transient characteristics of
drivers.  Usually the V-t curves are used as a time
dependent scaling coefficient, scaling the I-V curves
from 0 to 1 or 1 to 0 as time goes by.  If you are
interested in how this works, you can look at my
presentation and a VHDL-AMS implementation of this
algorithm at:

http://www.eda.org/pub/ibis/summits/jun03b/muranyi1.pdf

pages 5, 8, 9, and the VHDL-AMS code is at:

http://www.eda.org/pub/ibis/summits/jun03b/IBIS_basic_IO.vhd=20

I hope this helps.

I have one question regarding this, does an IBIS which is generated from =
DC
simulations can accurately reflect the dynamic  voltage behaviour that =
our
I/O's undergo.
Thanks,
Sanchayan
