Abstract

Quantum-dot Cellular Automata (QCA) is the alternative approach to synthesize the logic circuit with high density and low power dissipation to overcome the limitation of current VLSI technology. The underlying regular clocking scheme plays a significant role in the systematic cell layout, scalability, and reliability of the QCA circuit. This work analyzes the impact of genetic algorithm (GA) on regular clock based QCA circuits for less power dissipation. The elitism-based methodology is utilized to effectively realize multi-output boolean functions, embedding regular clocking schemes. A detailed analysis of power dissipation with different regular clocking schemes is reported. QCADesigner is used for logic synthesis, whereas QCAPro and QCADesignerE have been utilized for energy dissipation analysis.KeywordsQCAGenetic algorithmRegular clockingPower analysisQCAProQCADesignerE
