Anil,
If you have a data book with enough information it may be
possible to type up the IV curves and edge rates by hand
and make an IBIS model that way. But usually you are
better off measuring the necessary information in the
lab or using SPICE. The accuracy of the data book method
will most likely be the lowest. The lab measurements could
be more accurate than SPICE as far as matching the actual
device, but could include some noise which can be eliminated
with SPICE, and the measurements may not cover all the ranges
and process corner skews you would like to have. SPICE
would be the best from that perspective, but your data will
only be as accurate as the SPICE model is.

Hi Experts,
If SPICE model is not given, how to
generate IBIS model for that IC (other than Lab or
Direct measurement) ? Or. Is not possible to generate
IBIS model with out SPICE model (other than Direct
measurement ) of an IC?
Please answer to these Questions.
with regards,
anil.
