Semi-random net reordering for reducing timing variations and improving signal integrity

This work discusses the Semi-Random Net Reordering (SRNR) technique as a means to improve signal integrity and predictability of timing characteristics for wide routing bundles. The work shows that SRNR is capable of almost 90% reduction in induced noise and noise variation between wires of a routing bundle. The technique is also capable of considerable improvements in worst case propagation delay and delay variations as well as improvements in transition speed and its variations. SRNR has the advantage of close-to-zero cost and applicability even under the strictest of routing methodologies.
