ABSTRACT:
A computer readable storage medium includes executable instructions to receive a specification of a combinational logic circuit. The specification of the combinational logic circuit is converted to a Single-Rail un-encoded circuit and a Dual-Rail encoded circuit, which periodically encodes a null value, a first valid state and a second valid state on two wires. A logic operation of the Single-Rail un-encoded circuit transpires during processing of a null value by the Dual-Rail encoded circuit.
