In-Field Test for Permanent Faults in FIFO Buffers of NoC RoutersAbstract:
This paper proposes an on-line transparent test technique for detection of latent hard faults which develop in first input first output buffers of routers during field operation of NoC. The proposed transparent test is utilized to perform online and periodic test of FIFO memory present within the routers of the NoC. Simulation results show that periodic testing of FIFO buffers do not have much effect on the overall throughput of the NoC except when buffers are tested too frequently. The proposed architecture of this paper analysis the logic size, area and power consumption using Xilinx 14.2.
