Original Abstract Submitted
Some embodiments provide a method for performing an electronic design automation (EDA) operation with respect to a circuit component that is defined on a layer of an EDA design layout. The layer is defined by (i) a plane defined along x- and y-axes and (ii) having a thickness along a z-axis. The method uses a wafer shape simulator to generate multiple two dimensional (2-D) shapes for the circuit component with each 2D shape representing a different predicted manufactured cross x-y section of the component at a different location along the z-axis. The method uses the 2-D shapes to generate, for the circuit component, a predicted-as-manufactured three dimensional (3-D) shape that deviates along the z-axis. The method performs an EDA operation for the circuit component using the predicted-as-manufactured 3-D shape.
