An integrated circuit for performing a design for testability (DFT) scan test is provided. The integrated circuit includes at least one scan chain including a plurality of flip-flops, at least one interface scan chain including a plurality of flip-flops, a decompressor configured to be connected with an input terminal of the at least one interface scan chain and to decompress a first input signal and then transmit it to the at least one scan chain, a compressor configured to be connected with an output terminal of the at least one scan chain and to compress an output signal of the at least one scan chain, and at least one multiplexer configured to be connected with the decompressor and to selectively output an output signal of the decompressor or a second input signal in response to a control signal. |
