PROBLEM TO BE SOLVED: To readily detect a circuit portion where a handshake is performed from a circuit to be inspected.SOLUTION: A circuit analysis method comprises the steps of: detecting a FF 25 which operates with a clock signal CK1, a synchronizer 31, a FF 28 which operates with the clock signal CK2, and a synchronizer 32 from circuit information stored in a storage section 11, the synchronizer 31 including a FF 26 which receives an output signal of the FF 25 and operates with a clock signal CK2, and the synchronizer 32 including a FF 29 which receives an output signal from the FF 28 and operates with the clock signal CK1; detecting a loop portion L including the synchronizer 31 and the synchronizer 32 from the circuit information; and determining a circuit portion 20 including the loop portion L connected to either of a transmission section 21 and a reception section 22 which operate with clock signals differing from each other as a handshake section for executing a handshake procedure on transmitting/receiving a signal between the transmission section 21 and the reception section 22. |
