We propose a novel single event fault/error model based on logic induced fault encoded directed acyclic graph (LIFE-DAG) structured probabilistic Bayesian networks, capturing all spatial dependencies induced by the circuit logic. The detection probabilities also act as a measure of soft error susceptibility (an increased threat in nanodomain logic block)(More)
We propose a new switching probability model for combinational circuits using a<b>Logic-Induced-Directed-Acyclic-Graph</b>(LIDAG) and prove that such a graph corresponds to a<b>Bayesian Network</b>guaranteed to map all the dependencies inherent in the circuit. This switching activity can be estimated by capturing complex dependencies (spatio-temporal and(More)
— In this paper, we report Magnetic Quantum Cellular Automata (MQCA) realization using multi-layer cells with tilted polarizer reference layer with a particular focus on the critical need to shift towards the multi-layer cells as elemental entities from the conventional single-domain nanomagnets. We have reported a novel spin-transfer torque current induced(More)
With the goal of building an hierarchical design methodology for quantum-dot cellular automata (QCA) circuits, we put forward a novel, theoretically sound, method for abstracting the behavior of circuit components in QCA circuit, such as majority logic, lines, wire-taps, cross-overs, inverters, and corners, using macromodels. Recognizing that the basic(More)
We propose a novel, non-simulative, probabilistic model for switching activity in sequential circuits, capturing both spatio-temporal correlations at internal nodes and higher order temporal correlations due to feedback. This model, which we refer to as the temporal dependency model (TDM), can be constructed from the logic structure and is shown to be a(More)
In this paper, different circuits of Quantum-dot Cellular Automata (QCA) are proposed for the so-called coplanar crossing. Coplanar crossing is one of the most interesting features of QCA because it allows for mono-layered interconnected circuits, whereas CMOS technology needs different levels of metalization. However, the characteristics of the coplanar(More)
