    • PROBLEM TO BE SOLVED: To provide a circuit simulation method that properly estimates parasitic resistance of a terminal part of a semiconductor resistor element. SOLUTION: The simulation method of a semiconductor circuit includes a well resistor element 102 having a terminal part and a resistance body part, and a contact CT formed on the terminal part. In this case, the parasitic resistance Rt0 of the terminal part between the contact CT and the resistance body part is modeled by an expression Rt0=ρ 0 ×(L'+L' 0 )/(L'×(W'+W' 0 )). In the expression, ρ 0 , L' 0 , W' 0 indicate fitting parameters, L' indicates a length of the terminal part in a longitudinal direction of the well resistor element, and W' indicates a width of the terminal part in a width direction of the well resistor element.
