Abstract
Methods and systems for the integration of models and accurate predictions to score the circuit design, which translates to a more accurate and less complex yield prediction. In the present inventive approach, the computer-implemented methods and systems use at least one processor that is configured for performing at least predicting a physical realization of a layout design based at least in part on one or more model parameters, determining one or more hotspots associated with the layout design, determining a score for each of the one or more hotspots associated with the layout design, and categorizing the one or more hotspots according to at least the score in some embodiments. In some embodiments, the methods or the systems further use at least one processor for the act of determining one or more hotspots by using at least the design intent or the manufacturing information.
