Abstract
In one embodiment, the invention is a method and apparatus for soft hierarchy-based synthesis for large-scale, high-performance circuits. One embodiment of a method for physically synthesizing a design of an integrated circuit includes compiling a logical description of the design into a flattened netlist, extracting a soft hierarchy from the flattened netlist, wherein the soft hierarchy defines a boundary on a die across which cells of the integrated circuit are permitted to move, and placing a cell of the integrated circuit on the die in accordance with the soft hierarchy.
