Methods for modifying a layout design of an integrated circuit using model-based retargeting are provided. In one embodiment, a method for modifying an integrated circuit layout design includes providing an initial integrated circuit layout design, correcting the initial layout design for etch-induced lithography errors to generate an etch-corrected layout design, and fragmenting the etch-corrected layout design to generate a fragmented layout design comprising a plurality of fragments. The method further includes performing a bridging condition simulation and a pinching condition simulation on the fragmented layout design and calculating a required movement for at least one fragment of the fragmented layout design based on the bridging condition simulation and the pinching condition simulation. Still further, the method includes modifying the fragmented layout design by moving the at least one fragment in accordance with the required movement to generate a modified layout design and performing optical proximity correction on the modified layout design.
