Abstract

In this work we present a novel probabilistic modeling tool (QCAPro) to estimate polarization error and non- adiabatic switching power loss in Quantum-dot Cellular Automata (QCA) circuits. The tool uses a fast approximation based technique to estimate highly erroneous cells in QCA circuit design. QCAPro also provides an estimate of power loss in a QCA circuit for clocks with sharp transitions, which result in non-adiabatic operations and provides an upper bound of power expended. QCAPro can be used to estimate average power loss, maximum and minimum power loss in a QCA circuit during an input switching operation. This work will provide a good platform for researchers who wish to study polarization error and power dissipation related issues in QCA circuits.
