Abstract
A circuit for implementing a scan chain in programmable resources of an integrated circuit is described. The circuit comprises a programmable element configured to receive an input signal and generate an output signal based upon the input signal; a selection circuit configured to receive the output signal generated by the programmable element at a first input and to receive a scan chain input signal at a second input, wherein the selection circuit generates a selected output signal in response to a selection circuit control signal; and a register configured to receive the selected output signal of the selection circuit.
