Abstract
Disclosed are methods and mechanisms for implementing tessellation-based processing of an integrated circuit design. Tessellation based routing of objects on an integrated circuit layout can be performed by identifying a spacing rule for tessellating at least a portion of the integrated circuit layout, forming one or more plane figures in the tessellation having one or more edges compliant with the spacing rule, the edges of the one or more plane figures forming a contour derived from a shape of a blockage object, and identifying a routing path along at least part of the one or more edges. Packing and pushing of objects may be performed using this approach.
