Scalability of Network-on-Chip (NoC) as a promising solution for many-core systems can be
jeopardized due to reliability challenges such as aging in advanced silicon technology.
Previous mitigation techniques to protect NoC are either offline, while aging is strictly
influenced by runtime operating conditions, or impose significant overheads to the system.
This paper presents an online monitoring method through a Centralized Aging Table (CAT)
for routers in NoCs. Router's capacity in flits, which are the main stimuli in routers, is …
