An integrated circuit device includes a plurality of flip flops configured into a scan chain. The plurality of flip flops includes at least flip flop of a first type and at least one flip flop of a second type. A method includes generating a first scan clock signal for loading scan data into at least one flip flop of a first type, generating a second scan clock signal and a third scan clock signal for loading the scan data into at least one flip flop of a second type, and loading a test pattern into a scan chain defined by the at least flip flop of the first type and the at least one flip flop of the second type responsive to the first, second, and third scan clock signals.
