Circuit simulation method, circuit simulation device, and circuit simulation program and computer readable storage medium onto which the program is stored

摘要

The present invention provides a circuit simulation method for a semiconductor device in which the circuit configuration is specified by a netlist. First, variations in the layout pattern and arrangement of elements used in the semiconductor device are formulated into an equation including parameters (S110). Next, the parameters included in the equation are put into element parameter groupings corresponding to each element, and the element parameter groupings are stored in storage means (S120). Then, the parameters in the element parameter groupings are varied in accordance with the conditions obtained from variations in manufacturing process with respect to the semiconductor device (S130). Then, these varied parameters are used to execute a circuit simulation with processing means (S140).
