PROBLEM TO BE SOLVED: To provide a sequential circuit which can be operated faster than a maximum operating frequency determined by a maximum delay data path and can improve performance as a result, and an acceleration method thereof. SOLUTION: A sequential circuit including a combination circuit has a detection circuit (FF_L and XNOR) which detects operation start of a data path having a delay value exceeding a clock term; and a change circuit (GCB) which changes only the clock term at a time when the detection circuit detects the operation start of the data path, into such a clock term as satisfying timing of the relevant data path.
