CMOS device scaling is facing a daunting challenge with increased parameter variations and exponentially higher leakage current every new technology generation. Thus, researchers have started looking at alternative technologies. Magnetic Quantum Cellular Automata (MQCA) is such an alternative with switching energy close to thermal limits and scalability down to 5nm. In this paper, we present a circuit/architecture design methodology using MQCA. Novel clocking techniques and strategies are developed to improve computation robustness of MQCA systems. We also developed an integrated device/circuit/system compatible simulation framework to evaluate the functionality and the architecture of an MQCA based system and conducted a feasibility/comparison study to determine the effectiveness of MQCAs in digital electronics. Simulation results of an 8-bit MQCA-based Discrete Cosine Transform (DCT) with novel clocking and architecture show up to 290X and 46X improvement (at iso-delay and optimistic assumption) over 45nm CMOS in energy consumption and area, respectively.
