Design and Analysis of Digital Circuits using Quantum Cellular Automata and Verilog

Advancement from Verilog for the design and development of digital ICs is the innovation in QCA (Quantum Cellular Automata) Design which represents ideal cell automation using Quantum dots. QCA Design uses a transistor less computation technology which can produce high-density Nanoscale transistor. The main area of concentration in this paper is to simulate design and comparison of digital circuits using QCA Designer and Verilog Code, more specifically multiplexers and demultiplexers. The simulation results of these two digital circuits using QCA Designer and Verilog code are shown separately along with a performance comparison table. It was observed that they seem to be the same. But., while we consider other parameters like time, space, speed and sensitivity., we truly get to know that QCA design is more reliable when compared to Verilog Code Design. QCAD is a free computer-aided design software application for 2-Dimensional design and drafting. Multiplexers are used in telephone networking, computer memory, and transmission from the computer system of a satellite and in many more fields. Demultiplexers are used in Communication Systems, ALU (Arithmetic Logic Unit) and many other fields.
