Abstract
Disclosed is a method and system for removing hardware overlap for use with a computer aided design apparatus. The method and system remove overlap by separately classifying all free blocks and blocks fixed in place, and then shifting cells between free blocks while maintaining the same relative ordering of the cells. Thus, all move bounds are respected and only cells that exist in free blocks actually move. The operation takes place one partition at a time, whereby a typical partition includes a row of cells.
