Abstract:
1. A method for floorplanning, comprising: providing an input file in an electronic format in a computer readable medium, wherein the input file comprises a first floorplan for a plurality of dies on a layout area, wherein each die among the plurality of dies comprises a plurality of blocks, and connections for the plurality of blocks within each die and connections for the plurality of dies are specified by a netlist; using a processor executing instructions that are stored on a computer memory device connected to the processor, performing a routing congestion analysis for the first floorplan based on the netlist to identify a first hot spot between a first die and a second die; using a processor executing instructions that are stored on a computer memory device connected to the processor, inserting a spacer block at the first hot spot between the first die and the second die to result in a second floorplan; generating a photomask pattern based on the second floorplan; and manufacturing a photomask based upon the photomask pattern.
