Online Network-on-Chip Switch Fault Detection and Diagnosis Using Functional Switch Faults
نویسندگان
چکیده
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. Key-Words: Network-on-Chip, Switch, Online Testing, Functional Fault Model, Fault Diagnosis. Categories: B.4.3, B.4.5, B.8.1

Fault Diagnosis and Fault-Tolerant SVPWM Technique of Six-phase Converter under Open-Switch Fault
In this paper, a new open-switch fault diagnosis method is proposed for the six-phase AC-DC converter based on the difference between the phase current and the corresponding reference using an adaptive threshold. The open-switch faults are detected without any additional equipment and complicated calculations, since the proposed fault detection method is integrated with the controller required ...

متن کاملAn External Diagnosis method for Network-on-a-Chip
Over the past few years, Network-on-a-Chip (NoC) has become increasingly popular as a scalable interconnect infrastructure for IP cores. Simultaneously to developing new design paradigms, testing, diagnosis and debug strategies for such network architectures have to be considered. The previous works on testing NoCs have been mainly based on Design-for-Testability (DfT) approaches based on switc...
متن کاملAn Exhaustive Test Strategy Based on Flooding Routing for NoC Switch Testing
An exhaustive test strategy based on flooding routing for NoC switches is presented in this paper. Some test-mode hardware is added to the switches to enable them to multicast their incoming packets thus examining all existing routes in the network. A test environment based on high-level switch faults is used which injects high level routing faults into the NoC-Under-Test and considers the tota...
متن کاملReliability and Performance Evaluation of Fault-aware Routing Methods for Network-on-Chip Architectures (RESEARCH NOTE)
Nowadays, faults and failures are increasing especially in complex systems such as Network-on-Chip (NoC) based Systems-on-a-Chip due to the increasing susceptibility and decreasing feature sizes. On the other hand, fault-tolerant routing algorithms have an evident effect on tolerating permanent faults and improving the reliability of a Network-on-Chip based system. This paper presents reliabili...
