| Abstract: | This paper introduces a SER(soft error rate)analysis algorithm using a frequency method which provides a fast and accurate technique to calculate the effects of electrical masking and latching window masking.The frequency method is an approach to analyze the propagation of transient fault using frequency features of each logical gate and signal.It is divided into two procedures,one is linear system procedure,the other is nonlinear system procedure.In linear system procedure,the frequency method calculates t... |
