Abstract: Characteristics of a circuit element are predicted accurately by taking account not only of the temperature variation due to self-heating of the element but also of temperature variation due to heat transmission from an adjoining heater element. With reference to an electric network supplied from an electric network input unit (2) and a heat network supplied from a heat network input unit (3), a simulation unit (4) determines a first heat generation temperature resulting from the amount of self-heat generation of that element and a second heat generating temperature resulting from the amount of heat flowing into that element from other elements, respectively, for a plurality of elements which make up a semiconductor integrated circuit, calculates the element temperature of that element based on the first and second heat generation temperatures, and then calculates the voltage value and the current value in the element at that element temperature based on previously provided data indicative of temperature dependency of that element.
