摘要：A method of designing a circuit includes designing a first layout of the circuitbased on a first plurality of corner variation values for an electrical characteristic of a

corresponding plurality of back end of line (BEOL) features of the circuit. Based on thelayout, a processor calculates a first delay attributable to the plurality of BEOL featuresand a second delay attributable to a plurality of front end of line (FEOL) devices of thecircuit. If the first delay is greater than the second delay, a second layout of the circuit isdesigned based on a second plurality of corner variation values for the electrical

characteristic of the corresponding plurality of BEOL features. Each corner variation valueof the first plurality of corner variation values is obtained by multiplying a correspondingcorner variation value of the second plurality of corner variation values by acorresponding scaling factor.
