Abstract
A method includes tracing from an observation point in a circuit to an input of the circuit to produce a cone of influence that includes a plurality of components of the circuit. The plurality of components is connected at a plurality of nodes in the cone of influence and the plurality of components includes a plurality of logic elements. The method also includes, for each node of the plurality of nodes, determining an observability probability that a logical high or low value at a corresponding node propagates to the observation point. The method further includes determining a weighted soft error probability for each logic element of the plurality of logic elements and determining a weighed soft error failure mode distribution for the cone of influence.
