Reliability for network‐on‐chips has been widely researched in last decades not only to support the rapid growing requirement of on‐chip communication but also to address the challenge on reliability due to aggressive technology scaling. Simulation is the most common method to evaluate the capacity of reliability design but its cost is significant. Therefore, it is necessary to calculate the capacity for reliability of a design with light‐weight mathematic models. A model for faults on links is described to calculate the delivery rate of networks based on a Markov chain fault model, fault‐tolerant configuration and network traffic. The calculation results show accurate approximation of simulation results.
