Guiseppe,
The purpose of IBIS (Input Output Buffer Information Secification) is to
describe the Input/Output characteristics
through V/I curves without providing information on transistor level (
like SPICE). IBIS models are behavior models for digital ICs for Signal
Integrity and EMC analysis.

Yes, within a PCB EMC analysis it is a way to describe the electrical
behavior of the connected buffers.If you talk about external
interferences you are speaking in terms of succeptibility. If you do
such kind of simulations with digital nets on a PCB you can use IBIS to
model the buffer influences.

You can find IBIS information on http://www.eia.org/eig/ibis/ibis.htm
For EMC-Simulation you can look on http://www.incases.com

I have a question about IBIS
modelling, but please bear in mind that
the only think about ibis I known is that it is a high
level modelling of electonic devices;
So I' m a complete beginner in this field.The question is:
Do you think IBIS usage is useful for EMC analisys ?
You can find IBIS information on http://www.eia.org/eig/ibis/ibis.htmI mean EMC phenomena due to external interferences
and not due to Signal Integrity problem.Where i can find someting ( on the NET) of general like an
overview to read about IBIS ?
For EMC-Simulation you can look on http://www.incases.com
