Abstract
A fast method to detect hot spots using foundry independent models that do not require RET/OPC synthesis is presented. In some embodiments of the present invention, sensitive spots are located. Lithography models are used to simulate the geometry near the sensitive spots to produce a model of the area around the sensitive spots. The sensitive spots are scored using a measure such as intensity (of light) or scoring based on contrast.
