Abstract This paper presents accurate models for the analysis of fault trees based on stochastic logic. To produce the models, probabilistic analysis of static, dynamic and temporal gates is carried out and the probability models are converted to their equivalent stochastic logic gates. A hardware template is also designed for each stochastic logic gate. In the proposed method, users provide fault rates of basic events and immediately evaluate system reliability. Experimental results show that the proposed method is more accurate than previous methods using the proposed stochastic logic gates for dynamic and temporal fault trees. The formula was validated using the Markov model for exponential failure distribution events. The proposed model is applicable for both exponential and non-exponential distributions.
