Abstract :
An efficient approach is presented and demonstrated which enables the simultaneous simulation of the impact of several sources of process variations, ranging from equipment-induced to stochastic ones, which are caused by the granularity of matter. Own software is combined with third-party tools to establish a hierarchical simulation sequence from equipment to circuit level. Correlations which occur because some sources of variability affect different devices and different device quantities can be rigorously studied.
