Kesav,
IBIS doesn't specify or recommend any voltage or time step size
for the tables. You need to decide on that for yourself.
However, note that you do not have to evenly space the points
along the x-axis in the tables. This is useful for making
smaller step sizes in the regions where your curves change
fast.
Be careful when you use s2ibis, if I am not mistake, it can
only give you evenly spaced x-axis for the tables.

Hi IBIS experts,
I am interested to capture part of the VI curve (pullup,pulldown, ground clamp and power clamp) range in small step size.
S2IBIS tool by default takes 0.05 or 0.1 V step size. I would like to know does IBIS spec recommends any specific step size.
Could any one please let me know how to go about making VI curves for small step size other than default value.
Thanks,
Kesav.
