Abstract:

With the advent of manufacturing process of integrated circuit on the nanoscale,digital circuits are more vulnerable to failure of temporal deviation due to aging,process issue and soft errors which poses great threat on "temporal security".Based on an analysis of the model of fault signal's influence on stability invasion,the article proposes a new model for fault detection.This model enhances the existing fault detection and uses the C unit stability as the output of the detector unit.The simulation results show that this solution has obvious advantage in speed and resources consumption over the existing ones.

Key words: timing variation;online fault detection;signal stability;aging sensing
