An integrated circuit includes a first signal processing circuit in which first combination circuits and scan FFs are connected in an order of a scan FF, a first combination circuit, and a scan FF; a second signal processing circuit including a second combination circuit different from the first combination circuit; a first selection circuit configured to select data from a scan FF on an input side of one first combination circuit or data from an input terminal of the second signal processing circuit, and to output the data to the second combination circuit; and a second selection circuit configured to select data from another first combination circuit different from the one first combination circuit or data from the second combination circuit, and to output the data to the scan FF on an output side of the another first combination circuit.
