Post-layout logic duplication for synthesis of Domino circuits with complex gates

Logic duplication to resolve the logic reconvergent paths problem encountered in Domino logic synthesis is expensive in terms of area and power. In this paper, we propose a combined logic duplication minimization and technology mapping scheme for Domino circuits with complex gates. The logic duplication is performed as a post-layout step as the duplication cost is minimized based on accurate timing information. Experimental results show significant improvements in area, power, and delay.
