Hierarchical modeling approach for system level ESD analysis: From hard to functional failure

With the increased number of embedded systems into our surrounding area, the electronic devices are exposed to more severe environments and have to survive ElectroStatic Discharges (ESD). Both hard and functional failures have to be guaranteed. In this paper, we will present the methodology we started to develop eight years ago to predict the impact of (ESD). Through two main examples, we will show that a behavioral modeling of the device can give good simulation results. The next step will be the implementation of failure criteria to predict both hard and functional robustness. This paper is a summary of the various results obtained.
