Abstract:
A Quantitative approach based on analytical-model is proposed to quickly and accurately predict Transient Fault (TF) Susceptibility in combinational circuits.Accurate pulse generation model is relied on a precharacterization method,while a block-based algorithm,appropriately taking into consideration the attenuation and masking effects,is proposed for the analysis of pulse propagation.Taking advantage of these methods,we implement and validate a Transient-Faults Susceptibility Analysis (TFSA) tool.Experimental results on ISCAS benchmark circuits show TFSA achieves good accuracy compared to previous works,with notable speed-up for larger circuits,which can provide efficiently TF Susceptibility prediction for high-reliable circuits design.
