An objective is to provide a semiconductor integrated circuit apparatus capable of analyzing factors that exert an influence upon an actual operation of a semiconductor integrated circuit that is actually working, and further of reducing its factors. A semiconductor integrated circuit that is an object of measurement, and a measurement circuit for measuring a physical amount, which exerts an influence upon the actual operation of the semiconductor integrated circuit, such as jitter or noise jitter, and noise of this semiconductor integrated circuit are configured on an identical chip. Also, a measurement result of the measurement circuit of the present invention is analyzed, and is fed back to a circuit for adjusting the semiconductor integrated circuit that is an object of measurement.
