Abstract: A circuit for routing data in an integrated circuit device is described. The circuit comprises an input/output port; an interface circuit coupled to the input/output port and configured to receive data, the interface circuit comprising a selection circuit enabling the selection of the data and a predetermined value; and a control circuit coupled to control the selection circuit; wherein the control circuit holds the input/output port at the predetermined value during a partial reconfiguration of the integrated circuit device in response to a control signal. A method of configuring a circuit for routing data in an integrated circuit device is also described.
