More Information
Summary:Aspects of the invention include systems and methods configured to provide hierarchical circuit designs that makes use of a color decomposition of library cells having boundary-aware color selection. A non-limiting example computer-implemented method includes placing a plurality of shapes within a hierarchical level of a chip design. The plurality of shapes can include a top boundary shape, a bottom boundary shape, one or more center boundary shapes, and one or more internal shapes. A hierarchical hand-off region is constructed by pinning the top boundary shape to a first mask, pinning the bottom boundary shape to a second mask, and pinning the one or more center boundary shapes to a same mask. The same mask is selected from one of the first mask and the second mask.
