Abstract
Circuit data on a semiconductor integrated circuit, design constraints as to design of the semiconductor integrated circuit, air gap information on air gap creation in the circuit data, and an air gap volume constraint specifying an allowable range for an air gap volume value are received. The sum total of the values of the volumes of air gaps created in the circuit data according to the air gap information is calculated. Upon detection that the calculated sum total of the air gap volume values falls outside the allowable range specified by the air gap volume constraint, the circuit data is optimized so that the design constraints are satisfied and the sum total of the air gap volume values falls within the allowable range.
