A method and computer program are disclosed for floorplanning and cell placement of an integrated circuit architecture that include steps of: (a) receiving as input a design for an integrated circuit architecture that includes a plurality of modules and an internal I/O ring; (b) creating a floorplan to define an area for placing module cells for each module in the plurality of modules wherein for each module that overlaps the internal I/O ring, an area of intersection between the area defined for placing the module cells and an area bounded by a side of the internal I/O ring for which the area of intersection is least is a global minimum for the plurality of modules; and (c) generating as output the floorplan for the integrated circuit architecture.
