US Patent 7137091 Hierarchical repeater insertion

A method and system for inserting repeaters at different levels in a processor hierarchy involve tracing a net in a processor circuit followed by inserting repeaters at different locations in the net. The net is a circuit trace of wiring between circuit elements of a circuit, the net being divided into two nets. One net includes internal circuit elements of a processor component and another net includes external circuit elements of a processor component. A repeater solution, which includes inserted repeaters coupled to the internal circuit elements, is instantiated to other processor components. Subsequently, after instantiation of the repeater solution, repeaters are inserted in the nets external to the processor component.
