  • System and method for compressed post-OPC data
    Patent number: 8191016
    Abstract: According to various embodiments of the invention, systems and methods for system and methods for compressed post-OPC data created during the design and manufacturing of integrated circuits. In one embodiment of the invention, the method begins by generating a post-OPC layout from a circuit layout during the design phase of a circuit. This post-OPC layout is generated by way of an OPC process. Next, a set of differences between the post-OPC layout and the circuit layout are calculated and a dataset containing these differences are generated In some embodiments the dataset is generated during the OPC process.
