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) a thickness along a z-axis. Based on the layer of the design layout, the method uses a wafer shape simulator to directly generate a predicted three dimensional (3-D) shape that represents a predicted manufactured shape of the component. The predicted 3-D shape has tapered sides that are offset from the z-axis based on a manufacturing process used to manufacture the circuit component that results in non-parallel sides of the component. The method performs an EDA operation for the circuit component using the generated 3-D shape.
