input capacitance

in hspice or spectra, does anyone know hot to get or calculate the input capacitance value(Cin) of a I/O cell?
help me. thx!
 

Re: input capacitance

to measure the input capacitance you may drive the port with a current.

So, by measuring the time it takes the signal to go between two different voltages you can deduce the input capacitance.

I=C . dV/dt

You must be sure that the parasitic capacitance due to interconects is considered and explicitly present in the netlist you are simulating
