Abstract

Fixed outline shaped and modifiable outline shaped random logic macros of an electronic circuit design are manipulated by modifying an outline of a modifiable outline shape macro based on criteria consisting of any one of a macro port weight value, a macro port ordering; a macro rapport constraint or a macro logic depth and placing resulting macros at locations on an integrated circuit (chip).
