ABSTRACT:
Intermediate resolution-enhancement state layouts are generated based upon an original non-resolution enhanced layout of an integrated circuit and an associated resolution-enhanced layout. The intermediate resolution-enhancement state layout includes fragments corresponding to parts of the original layout and biases associated with the fragments, where the biases indicate distances between the fragments and the resolution-enhanced layout. The fragments are also assigned attributes such as fragment type, fragment location, and biases. The intermediate resolution-enhancement state layouts can be combined to generate the layout for a full chip IC. Two or more intermediate resolution-enhancement state layouts are assembled and are locally reconverged to adjust the resolution enhancement associated with the intermediate resolution-enhancement state layouts and obtain the intermediate resolution-enhancement state layouts for the full IC.
