Position-dependent variation amount computation method and circuit analysis method

Abstract

Using layout position information as input, in a position-dependent variation amount calculation step, position-dependent variation amount information which is a variation amount of a characteristic parameter or a shape parameter variable depending on an arrangement position of each element constituting a design target semiconductor integrated circuit is calculated. Thereafter, a simulation is performed using circuit information. In the simulation, a value for the circuit information is corrected according to a position-dependent variation amount of the position-dependent variation amount information, and a result of the simulation is calculated. Accordingly, a simulation for a circuit characteristic using a variation amount depending on an arrangement position of a device and the like can be performed with layout position information for a semiconductor integrated circuit.
