Abstract
A system and method are provided for reducing signal skew. The method includes receiving a netlist having components and connections among the components. Each connection has at least one signal wire. A plurality of net groups is identified, each net group including at least some of the connections and for which equivalent routing is desired. For each net group, the method includes systematically routing connection paths between the components for the connections, each connection path extending between an output of one of the components and an input to at least one other of the components and including at least one path fragment. Routing includes, for at least one of the connections of the net group, routing at least one grounded shielding wire in a routing channel adjacent and parallel to at least one of the path fragments of the connection path.
