Post Synthesis-Optimization of Reversible Circuit using Template Matching

In this work, we propose an optimization technique for reversible circuits. The involved steps in this optimization are divided in two stages: First, we define templates and, second, we execute an optimization algorithm, where templates are applied on a specific order over the input circuit and exhaustively search through the circuit for possible replacements. The proposed optimization approach has been tested over a wide spectrum of benchmarks and improvement over state-of-the-art design approaches is registered.
