Why do the capacitance values ( CIOTB, CIOLR, CCLKTB, CCLKLR, CCLKLR ) in the Stratix "DC & Switching Characteristics" chapter of the handbook differ from the capacitive value ( Ccomp ) in the IBIS models?

Description
The capacitance value ( CIOTB, CIOLR, CCLKTB, CCLKLR, CCLKLR ) in the DC & Switching Characteristics (PDF) chapter of the Stratix® handbook refer to the pin capacitance whereas the capacitance value ( Ccomp ) in the IBIS models refer to the package capacitance.
