Disclosed is a semiconductor integrated circuit including a first storage circuit and a second storage circuit that respectively store logic levels of an input to the delay circuit and an output of the delay circuit when a logic level of a clock line is changed, and a determination circuit that determines whether or not the results of the first storage circuit and the second storage circuit coincide or not. Even if a transistor or a wiring that constitutes the semiconductor integrated circuit has been degraded due to secular change or the like, a possibility of an anomaly or a failure in one of the operation circuits caused by the degradation can be predicted before the anomaly or the failure occurs.
