Quantum Dot Cellular Automata (QCA), an emerging Field Coupled Nano computing which is the new paradigm of computation has to be analyzed for reliability and thermal stability and power dissipation. The main focus of this study is to analyze a high input majority voter based on 3 to 8 decoder for reliability using Bayesian network at a circuit level. The charge configuration flow indicated the reliability of the data transmitted and hence the behavior of the QCA Circuits was analyzed. The Casual Direct Acrylic graph was used to analyze the behavior of QCA circuits. The power dissipation of the QCA circuits was also analyzed using QCADesigner-E tool. Bayesian networks were generated using dagitty tool.
