Online Network-on-Chip Switch Fault Detection and Diagnosis Using Functional Switch Faults

This paper presents efficient methods for online fault detection and diagnosis of network-on-chip (noc) switches. the fault model considered in this research is a system level fault model based on the generic properties of noc switch functionality. the proposed method is evaluated by fault simulation in a platform using this system level fault model. the experimental results show that with a relatively low area overhead, a large number of noc switch faults can be detected and diagnosed.
