PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit device capable of correcting an error which occurs between a replica circuit and a real circuit. SOLUTION: A skew comparator circuit 10A compares a signal that is outputted from an oscillation circuit 15A and passed through an output circuit 06A of the real circuit and an input circuit 04A of the real circuit with a signal that is outputted from the oscillation circuit 15A and passed through a replica circuit 11A of an input circuit and a replica circuit 12A of an output circuit, to detect the delay error between the real circuit and the replica circuit.
