Abstract
A method for efficiently processing a design layout is described. In some embodiments, the method receives an original design layout and a modified design layout. The method identifies a change from the original design layout to the modified design layout by comparing the original and modified design layouts. The method of some embodiments then defines a region based on the location of the identified change within the modified design layout. The method performs a design operation (e.g., placing fills) only on the identified region of the modified design layout.
