ABSTRACT:
method of physical circuit design can include the steps of packing components of a circuit design that are dependent upon an architecture of the circuit design and assigning initial locations to each component of the circuit design. The components of the circuit design can be clustered by combining slices and including slices into configurable logic blocks according to design constraints, while leaving enough white space in the configurable logic blocks for post-placement circuit optimizations. The components of the circuit design then can be placed to minimize critical connections. The circuit design can be declustered to perform additional placer optimization tasks on the declustered circuit design.
