Introduction to IBIS Models

Hi all,

Is this document (Introduction to IBIS Models) still available from IBIS
website or elsewhere? Is there any other document that deals with "How to
obtain c_comp?"

Thanks
Prabhu

Subject: measuring c_comp using simulation

Hi,
 
In Arpad Muranyi's "Introduction to IBIS Models" (available from IBIS
website), there was a sample Spice netlist for a simulation to obtain the
value of c_comp. When I used this simulation for my buffer, the capacitance
ranged from 2pF to 8pF, with a mean of 5pF. In the example, the range was
only between 2 to 3pF. Should the mean value for the simulated capacitance
be used? What about obtaining min and max values for c_comp?
 
I would really appreciate any feedback. I have attached the sample Spice
file for reference.
 
Thanks very much,
Betty
