Associated with the ever growing integration scales is the increase in process variability. In the context of network-on-chip, this variability affects the maximum frequency that could be sustained by each link that interconnects two cores in a chip multiprocessor. In this paper the authors present a methodology to model delay variations in NoC links. They also show its application to several technologies, namely 45nm, 32nm, 22nm, and 16nm. Simulation results show that conclusions about variability greatly depend on the implementation context.
