Abstract :
While the design of signature analyzers for digital circuits has been well researched in the past, signature analyzers for analog signals are relatively unknown. In this paper, a novel signature analysis scheme for analog and mixed-signal circuits is proposed. The signatures possess the interesting properly that if the input analog signal is imprecise within certain bounds (an inherent property of analog signals), then the generated signature is also imprecise within certain bounds. A failure is indicated by the generated signature being different from the expected signature by a margin greater than a predetermined threshold
