Quantum-dot cellular automata (QCA) technology is one of the candidate technologies to replace CMOS in multi-valued logic (MVL) circuit designs, to overcome the problems of binary systems. One of the advantages of MVL systems is that they can process more information. Some techniques are essential to simulate and evaluate new multi-valued designs and their performance. This article introduces a new software platform for simulating Quaternary QCA (QQCA) circuits that can be run on computers on Windows and Linux computers is powerful and can run simulations with high accuracy. The presented tool provides the results in two formats. The first format is waveform and the second one is truth table . The presented software has a user-friendly interface that allows users to easily implement their QQCA circuits. Furthermore, the electrostatic energies for all cases in which the basic gates assume four values are determined and the step-by-step simulation process is described. The basic NOT, AND, and OR gates have already been simulated and validated by the relevant software.

“…QCA technology has received attention due to its high response speed and reduction of circuit dimensions with this technology [24,25]. In the construction of a QCA cell, electron beam lithography with the double layer resists is used on Si or Si/SiO2 substrate, and also quantum dots are deposited on an aluminum substrate [26].…”

Reducing the size of transistors to nano‐dimensions has brought new problems and challenges to the semiconductor field‐effect transistor industry. Therefore, quantum cells are considered as an alternative technology to solve these problems. The efforts of the past few years on the earth of nano‐electronics circuits have focused more on minimizing the cost of hardware by processing more than two values per basic action. In this paper, for the first time, the ternary XOR circuit has been designed and simulated in ternary quantum cells (TQCA) technologies. The proposed ternary XOR‐based on TQCA with 369 cells, area‐delay cost (m2 − scc) is 136.76, power equal to 1704.7 × 10−20 J equivalent to 106.4 eV, area 0.074128 μm2, and a delay of 1.25 clock was designed and simulated for validation with TQCAsim software. In addition, the ternary decoder circuit was simulated with 14 cells, cost (m2 − scc) is 0.0339, area 0.0021 μm2, and delay of one clock cycle. The comparison indicates that TQCA technology has unique behaviors and advantages in various criteria such as low power consumption, delay reduction, reduction of occupied space, and a significant increase in working frequency.
