In this paper we present a model for structural failures in nano-devices. Fault being considered include stuck-at and bridge faults only. This model is an extension of probabilistic model based on Gibbs energy distribution and belief propagation as presented in NANOLAB [1]. Results have been carried out on a 8-bit full adder circuit. Simulation results indicate that probabilistic TMR model represents bridge and stuck-at-1 faults better while deterministic model is more suited for stuck-at-0…

Probabilistic modeling approaches for nanoscale devices
A computational framework based on Markov Random Field, Probabilistic Transfer Matrices and probabilistic Decision Diagrams is developed using MATLAB for design and analysis of combinational circuits at nanoscale and it is observed that Bayesian Network and Probabilism Decision diagrams have least time complexity among these approaches.

NANOLAB-a tool for evaluating reliability of defect-tolerant nanoarchitectures
This paper has developed MATLAB-based libraries for fundamental logic gates that can compute probability distributions and entropies at the outputs for specified discrete input distributions and in the presence of noise at the inputs and interconnects, and automates the evaluation of reliability measures of combinational logic blocks.
A Probabilistic Approach to Nano-computing
A probabilistic-based design methodology for designing nano-scale computer architectures based on Markov Random Fields (MRF), which can express arbitrary logic circuits and logic operation is achieved by maximizing the probability of state configurations in the logic network.

This paper compares the relative performance of four such techniques: R-fold multiple redundancy; cascaded triple modular redundancy; von Neumann's multiplexing method; and a reconfigurable computer technique.
Probabilistic Logic and the Synthesis of Reliable Organisms from Unreliable Components
The paper that follows is based on notes taken by Dr. R. S. Pierce on five lectures given by the author at the California Institute of Technology in January 1952, and it is the author's conviction that error should be treated by thermodynamic methods, and be the subject of a thermodynamical theory.
