Abstract: Disclosed is an improved approach for implementing a three-dimensional integrated circuit design with mixed macro and standard cell placement. This approach concurrently places both the macros and standard cells of the 3D-IC design onto two or more stacked floorplan and optimize the instance locations by timing, density, wire length and floorplan constraint.
