One Poison is Antidote Against Another Poison

The presence of open-faults in NoC channels drastically drops packets while routing them causing severe degradation of network performance. Nevertheless, it can still be compensated by utilizing a fault-repairing scheme. This paper shows how the performance of a NoC architecture can be improved through self-repairing of open channels using short-defects. Simulation results reveal that the performance degrades to nearly 30% when the channels suffer from manufacturing open-faults, and to 10% when they are self-repaired with the help of co-existent short-defects. Thus, the overall performance can be improved beyond 65%.
