Improving timing characteristics through Semi-Random Net Reordering

Abstract

This work discusses the Semi-Random Net Reordering (SRNR) technique as a means to improve signal integrity and predictability of timing characteristics for wide signal busses. SRNR is able to reduce induced noise, signal propagation delay, signal transition speed, and their variations amongst the different wires comprising the bus. SRNR produces a faster routing structure that is more uniformly behaved. It has the advantage of zero cost and applicability under the strictest routing methodologies.
