This paper evaluates fault-tolerant behavior of an NoC router through simulation-based method. A structural-level VHDL environment has been employed to estimate fault injector signal's (FIS) effects. Different fault models such as dead clause, stuck-then, micro-operation, crosstalk, and SEU have been injected to evaluate the transient faults' effects. According to the results, up to 48% of the injected faults cause system failure and also about 51% are overwritten before turning into errors.

Almost 70%, 31%, and 35% of injected faults are overwritten in buffer, routing unit, and switch components, respectively. Routing unit is also recognized as the most tenuous component.
