Cross-Layer Analysis of Permanent Faults in Asynchronous NoCs for Neuromorphic Computing
Giuseppe Chessa, Yuyi Yang, Edward S Jones, Michele Favalli, Davide Bertozzi
TL;DR: A cross-layer fault simulation framework is developed that couples a gate-level model of the NoC with a high-level SNN simulator, enabling accurate propagation of hardware-level routing anomalies to SNN-level behavioral deviations.
The robustness of Spiking Neural Networks (SNNs) critically depends on the integrity of spike routing in neuromorphic hardware. While most prior work has focused on compute and memory faults, permanent faults in the Network-on-Chip (NoC) carrying the digital encoding of spike eve…
