Parasitic-Aware Blockage

A method for extracting parasitic capacitances associated with a detailed blockage structure, the method comprising:

• deriving one or more parasitic-aware blockage polygons from the detailed blockage structure, wherein each of the one or more parasitic-aware blockage polygons represents a plurality of polygons of the detailed blockage structure;
• associating physical information with each of the one or more parasitic-aware blockage polygons, wherein the physical information represents physical characteristics of the represented plurality of polygons of the detailed blocking structure;
• and
• extracting parasitic capacitances based on the one or more parasitic-aware blockage polygons and the associated physical information.
