SETTOFF : a fault tolerant flip-flop for building cost-efficient reliable systems
SETTOFF : a fault tolerant flip-flop for building cost-efficient reliable systems
Conventional fault tolerance techniques either require big overheads or have limited reliability. We propose a novel fault tolerant flip-flop (SETTOFF) that addresses timing errors and soft errors in one cost-efficient architecture. In SETTOFF, most SEUs are detected by monitoring the illegal transitions at the output of a flip-flop and recovered by inverting the cell state. SETs, timing errors and the other SEUs are detected by a time redundancy-based architecture. For a 10% activity rate, SETTOFF consumes 35.8% and 39.7% more power than a library flip-flop in 120nm and 65nm technologies, respectively. It only consumes about 5.7% more power than the detection based RazorII flip-flop [1]. The result indicates that SETTOFF is suitable for building high reliable systems at lower cost than the traditional techniques.

Abstract
Conventional fault tolerance techniques either require big overheads or have limited reliability. We propose a novel fault tolerant flip-flop (SETTOFF) that addresses timing errors and soft errors in one cost-efficient architecture. In SETTOFF, most SEUs are detected by monitoring the illegal transitions at the output of a flip-flop and recovered by inverting the cell state. SETs, timing errors and the other SEUs are detected by a time redundancy-based architecture. For a 10% activity rate, SETTOFF consumes 35.8% and 39.7% more power than a library flip-flop in 120nm and 65nm technologies, respectively. It only consumes about 5.7% more power than the detection based RazorII flip-flop [1]. The result indicates that SETTOFF is suitable for building high reliable systems at lower cost than the traditional techniques.
