Scalable packet-switched Network-on-Chip (NoCs) are essential in undertaking the role of the communication medium in modern many-core systems. Consequently, the reliability of the NoC is critical for the operation of the system. In this work, we develop, design, implement, and investigate the NoCAlert engine at the Register Transfer Level (RTL). NoCAlert is a mechanism that can detect illegal decisions in the various components of the NoC router micro-architecture,...
