Description Existing floorplanners that use slicing floorplans are efficient in runtime and yet can pack modules tightly. However, none of them can handle pre-placed modules. In this paper, we extend a well-known slicing floorplanner [10] to handle preplaced modules. Our main contribution is a novel shape curve computation procedure which can take the positions of the pre-placed modules into consideration. The shape curve computation procedure is used repeatedly during the floorplanning process to fully exploit the shape flexibility of the modules to give a tight packing. Experimental results show that the extended floorplanner performs very well. 1 Introduction Floorplan design is an important step in the physical design of VLSI circuits. It is the problem of placing a set of circuit modules on a chip to minimize total area and interconnect cost. In this early stage of physical design, most of the modules are not yet designed and thus are flexible in shape (soft modules), some are completely de...
