C_comp value

Dear Gentleman ,

I have some doubts about the C_comp value inside the IBIS model.
I hope you can help me.

I read this definition inside the IBIS spec :

C_comp defines the silicon Die capacitance ..

but I did not understand well.
 This is the value I obtain from a parasitic extraction from layout
or it is
the input or output capacitance I can
read inside my chip Spec ?

 Thank you in advance for your help , Your Sincerelly
