Determining Soft Error Infliction Probability

摘要

A method, system and product for determining error infliction probability or probability. The method comprises obtaining a representation of a circuit, wherein the circuit comprises nodes, wherein the nodes comprise at least one critical node; obtaining a trace, wherein the trace comprises recorded values of the nodes in a plurality of cycles; determining, by a processor, a Soft Error Infliction Probability (SEIP) of a node, wherein the SEIP is a value representing a probability that a Single Event Upset (SEU) effecting the node in a cycle will inflict a soft error by propagating through the circuit to the at least one critical node, wherein said determining comprises simulating a propagation of the SEU from the cycle to consecutive cycles, wherein said simulating utilizes values from the trace which are associated with the consecutive cycles; and outputting the SEIP of the node.
