In-Field Test for Permanent Faults in FIFO Buffers of NoC Routers

 In-Field Test for Permanent Faults in FIFO Buffers of NoC Routers

 An on-line transparent test technique for detection of latent hard faults which develop in firstinput firstouptput buffers of routers during field operation of NoC. The technique involves repeating tests periodically to prevent accumulation of faults. A prototype implementation of the proposed test algorithm has been integrated into the router-channel interface and on-line test has been performed with synthetic self-similar data traffic.
