Abstract:
Software-based fault simulation can support all abstraction levels, is flexible and allows reliability assessment at different stages in the design process. Fault diagnosis and reliability analysis are increasingly important in circuit design and determine the product’s time-to-market. In this paper, we provide a new efficient method and systematic scheme for reducing the time for simulation of multiple simultaneous faults and/or multiple failure modes per element in an analogue circuit. By arranging similar multiple faults in groups, some so-called failure classes can be interpolated with an adequate precision rather than being evaluated by time-consuming simulation. The technique can be used to perform efficient multiple fault diagnosis based on multiple fault injection. Finally, the implemented procedure is validated with some simulation results.
