Dousti Department of Electrical and Computer Engineering, Science and Research Branch, Islamic Azad University, Tehran, Iran Journal Article 2019 05 04 Having a reliable simulation tool for evaluating the performance of each design is indispensable. Designing multiple-valued logic (MVL) systems help to overcome the limitations existing in binary systems. Quantum-dot cellular automata (QCA) is a technology that can be substituted for CMOS in MVL designs. This paper represents an exquisite software platform for designing and simulating circuits which are restricted to three-valued logic (Ternary) quantum-dot cellular automata (QCA). Working with TQCAsim is so convenient because it can run in both Windows or Linux based computers. It has a tenacious simulation engine that can warranty precise results. This tool shows the results in graphical formats. As well, designers can easily layout their ternary QCA designs by using various sets of CAD tools. In this paper, the ternary model of QCA and its energy calculation will be demonstrated. The simulation Process will be explained step by step. MIN, MAX, NOT, and XOR gates had been simulated already by this software. https://scientiairanica.sharif.edu/article_22243_6b6b3d010c898ee29ec6b7a5ec045183.pdf
