PROBLEM TO BE SOLVED: To surely perform verification of non-coincidence of an input about an analog circuit in a semiconductor integrated circuit in which a digital circuit and the analog circuit exist mixedly. SOLUTION: On the basis of layout information and circuit diagram information, coincidence of the layout of semiconductor integrated circuit and a circuit diagram is verified by comparison (S1-S3). On the basis of the layout information or the circuit diagram information, a first transistor to be connected with a prescribed power source, and a second transistor to be connected in series with the first transistor are detected (S4). On the basis of the layout information or the circuit diagram information, data (e.g. channel lengths L1, L2) concerning each channel of both of the detected transistors are extracted (S5). The extracted data concerning each channel are compared with each other, and it is decided whether the connection order of both transistors is right on the basis of the comparison, thereby performing a process corresponding to the decided result (S6-S9).
