  • IC physical design using a tiling engine
    Patent number: 10831964
    Abstract: In general, embodiments of the present invention provide systems, methods and computer readable media for generating a tiling for a physical placement of a plurality of circuits. The method includes generating a tiling including a plurality of tiles, where each tile identifies a tile geometric area, and a list of one or more of the circuits to be placed in the tile geometric area. The tiling is based on a description of one or more user constraints, where each user constraint identifies a constraint geometric area, and a characteristic of circuits to be placed in the constraint geometric area.
