Using boolean expressions to represent shapes within a layout of an integrated circuit

摘要

One embodiment of the present invention provides a system that facilitates representing a shape within a layout of an integrated circuit using a Boolean expression. The system operates by first receiving a representation of the shape and then converting the representation of the shape into a Boolean expression that is formed using a Boolean coordinate system expressed in a two-dimensional Gray code. The system then performs operations on the shape by performing Boolean operations on the Boolean expression for the shape.
