PURPOSE: A device and a method for optimally designing an IC having the same function and performance as the first circuit, and a recording medium recording a program for the same are provided to attain high optimization accuracy and reach desired analysis in a short time by combining optimization of each transistor and entire circuit. CONSTITUTION: An operating range judging tool(11) extracts a node voltage and a transistor current of the circuit, converts the extracted node voltage into an inter-node voltage of the transistor, and judges an operating range by using the inter-node voltage of the transistor and a threshold voltage of the transistor current. An operating range analyzer(12) extracts the node voltage and the transistor current of the circuit, converts the extracted node voltage into the inter-node voltage of the transistor, and displays a linear characteristic and a saturation characteristic by using the inter-node voltage of the transistor and the transistor current. A sweep sensitivity analyzer(13) displays a change of an output property for the circuit when a circuit parameter is changed by alpha percentage.
