Abstract:
1. A method of circuit design, comprising: generating, by using a computer, a placed, routed, and optimized circuit design, including: wherein the placed, routed, and optimized circuit design obeys rules specifying positioning of each circuit element of the first set of circuit elements relative to other circuit elements of the first set of circuit elements, and the rules were created after creating the first set of circuit elements, wherein the netlist of the circuit design further includes additional sets of circuit elements of the circuit design, and the placed, routed, and optimized circuit design obeys additional rules specifying positioning of each circuit element of each additional set of circuit elements relative to other circuit elements within a same additional set of circuit elements, the additional rules being created specifically for the additional sets of circuit elements prior to the placing and routing of the additional sets of circuit elements, and one or more additional sets of the additional sets has one or more hierarchical relationships with one or more other additional sets of the additional sets.
