Abstract

Hierarchical layout synthesis of complex cells. In some embodiments, a method may include partitioning a cell into a plurality of subcells, where the cell represents a set of electronic components in an integrated circuit; identifying, among the plurality of subcells, a most complex subcell; synthesizing a layout of the most complex subcell for each of one or more side-port configurations; selecting a side-port configuration based upon the layout of the most complex subcell; and synthesizing a layout of one or more of the plurality of subcells neighboring the most complex subcell by propagating one or more constraints associated with the selected side-port configuration.
