I have a comment on Weston's comment on the number of data points.
I disagree on one point. Instead of increasing the number of points generated
in the IBIS file the spice to IBIS tool should improve the quality of the
I can hand build files with 50 points that out perform files with 400 points.
The big gain is that the FILE SIZE is reduced with higher accuracy.
Large IBIS files will take up many megabytes on 1000's of hard drives.
The V/I and V/T tables are the largest part of IBIS files.
Increasing them 4 x will generally increase the file size 3 x or more.
