As technology is scaling down, circuit reliability issues are major concerns because digital circuits are more susceptible to external noise sources. Soft Error is one such source which changes the voltage of internal nodes of the circuit. Hence it is necessary to design soft error (SE) immune digital circuits. In this paper, we proposed a novel SE immune latch circuit which operates at 0.5V using...
In many DSP applications (image and voice processing, baseband symbol decoding in high quality communication channels) several dBs of SNR loss can be tolerated without noticeable impact on system level performance. For power optimization in such applications, voltage overscaling can be used to operate the arithmetic circuitry slower than the critical circuit path delay while incurring tolerable SNR...
In this paper, we present a novel technique for online testing of feedback bridging faults in the interconnects of the cluster based FPGA. The detection circuit will be implemented using BISTER configuration. We have configured the Block Under Test (BUT) with a pseudo-delay independent asynchronous element. Since we have exploited the concept of asynchronous element known as Muller-C element in order...
Timing-error detection and recovery circuits are implemented in a 65 nm resilient circuit test-chip to eliminate the clock frequency guardband from dynamic supply voltage (VCC) and temperature variations as well as to exploit path-activation probabilities for maximizing throughput. Two error-detection sequential (EDS) circuits are introduced to preserve the timing-error detection capability of previous...
