Abstract:
1. A high-frequency-corresponding simulation apparatus comprising: an element setting unit which sets a plurality of elements corresponding to wiring patterns in accordance with circuit design information; a resistance-value calculation unit which calculates the total of resistance values each of which is the sum of the DC resistance value and skin resistance value of each of the elements as the total resistance value; a first determination unit which determines whether the total resistance value is less than a first threshold value; a sorting unit which sorts resistance values corresponding to the elements when the total resistance value is equal to or larger than the first threshold value in accordance with a determination result by said first determination unit; a second determination unit which integrates the resistance values starting with a resistance value having the smallest high-frequency element delay and determines whether the integration result reaches a value immediately before a second threshold value whenever the integration is executed; and an analysis unit which executes an analysis by using at least one of the elements corresponding to an integrated resistance value as a RLC model and using other elements than the at least one of said elements as high-frequency element models when said second determination unit determines that the integration result reaches the value immediately before the second threshold value.
