Hierarchical placement for macrocells: a 'meet in the middle' approach

Abstract

Placement and related aspects of the BEAR macrocell layout system are described. A combination of top-down and bottom-up heuristics is used to make best use of a hierarchical description. The interdependency of placement and routing is considered explicitly. Experimental results show a considerable improvement over previous approaches.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
