Connectivity condition for structural properties using a graph theoretical approach: Probabilistic reliability assessment
2013
IFAC Proceedings Volumes
Preserved Fulltext
In a structured system graphically represented, the satisfaction of structural properties depends on graphical conditions. ...
As an application of the proposed Boolean expression, we can define the reliability characteristics of the connectivity condition and for how much time it remains satisfied knowing the reliability characteristics ...

A scalable feature learning method on a graphical domain called node2vec algorithm had been utilized for efficiently extracting structural features of the netlist, providing a valuable database to exercise ...
The current work proposes to model the gate-level netlist as a Probabilistic Bayesian Graph (PGB) in the form of a Graph Modeling Language (GML) format. ...
As the structural information of gate-level netlist is transformed into the probabilistic graph, the statistical properties of a graph node conventionally equivalent to that of a sequential (flip-flop) ...
