Abstract
A rule based floorplanner for a macrocell array having a plurality of predetermined macrocells. The floorplanner uses a net list (23), a macrocell list (26), and a list of design constraints (31) and characteristics of the base array itself to derive an initial Burain score. A trial floorplan is attempted (33) and checked against a list of theoretical rules (39) and a list of empirical rules (38) to determine a measured Burain score (36) which accurately indicates the difficulty which can be expected when completing the design.
