    Abstract: A method and system for lithography simulation is disclosed. The method and system specify a subject region of a lithography image with a CD marker, specify a threshold intensity over the lithography image, specify a gradient to a threshold value of the threshold intensity, and calculate a sensitivity or ratio of change of an image boundary of the lithography image to lithography process variation.
