Abstract:

For of the encountered, this paper adopts the logic description and verification capability of the current EDA technology to design classical logic circuits as the replacement of reversible logic gates based on functional expressions to solve the bottlenecks of reversible logic synthesis in case of great circuit scale and complexity. The reversible ALU, described with conventional logic diagram, implements sixteen logic operations. Experimental results show that the proposed method is feasible and effective.

Key words: schematic, conventional logic, reversible logic, function replacement, function description and simulation
