Patent attributes
A layout modification method is performed by at least one processor. The layout modification method includes: analyzing, by the at least one processor, allocation of a plurality of specific layout segments of a circuit cell layout to determine a first specific layout segment and a second specific layout segment from the plurality of specific layout segments; determining, by the at least one processor, if the first specific layout segment and the second specific layout segment are coupled to a first signal level; and merging, by the at least one processor, the first specific layout segment and the second specific layout segment into a first merged layout segment when the first specific layout segment and the second specific layout segment are coupled to the first signal level.
