Abstract
In some embodiments, in a method performed by at least one processor, spaces among a plurality of layout segments is analyzed by the at least one processor to determine at least one first-type conflicted edge according to a first predetermined length. Spaces among the plurality of layout segments is analyzed by the at least one processor to determine a plurality of potential conflicted edges according to a second predetermined length different from the first predetermined length. At least one second-type conflicted edge is determined by the at least one processor according to the plurality of potential conflicted edges. If at least one odd-vertex loop is formed in the plurality of layout segments is checked by the at least one processor according to the at least one first-type conflicted edge and the at least one second-type conflicted edge to determine if a violation occurs in the plurality of layout segments.
