ABSTRACT:
A simulation apparatus for simulating a characteristic of a semiconductor circuit, including; a distribution information input unit for receiving a distribution information, the distribution information including a range and/or profile of distribution of a variation of a device parameter and/or a process parameter of the semiconductor circuit and being adaptive to an actual distribution; a random number generating unit for generating a random number on the basis of a probability responsive to the received distribution information; a characteristic calculation unit for calculating a dominant formula by using the random number to obtain a characteristic of the semiconductor circuit; and an output unit for outputting the resultant characteristic of the semiconductor circuit.
