Inherent reliability evaluation of Networks-on-Chip based on analytical models

Abstract

Reliability evaluation based on analytical models is a precise method for dependability analysis before and after designing the fault-tolerant systems. In this paper, we present the precise formulations for the inherent reliability of mesh-based NoCs that also depend on the employed routing algorithm and traffic model. Based on this analysis, the effects of some permanent failures in the links, switches or cores on the packet delivery of NoCs are determined. The models can be extended to evaluate the fault-tolerant methods in addition to other topologies and routing algorithms.
