 Analysis of Floorplanning Algorithms in VLSI Physical Designs
free download

D Batra ,ijater.com
Abstract The first step in the Physical Design flow is Floorplanning. The floorplanning stage
ensures that (1) every chip module is assigned a shape and a location, so as to facilitate
gate placement, and (2) every pin that has an external connection is assigned a location,
