1. A simulation apparatus comprising: a discrete events simulation section to do a discrete type simulation of components of a configured model as defined based on attribute information that is information on parts of the components of the defined configured model and based on connection information showing a connectional relationship among the components of the defined configured model; and a soft error rate computation processing section to compute a soft error rate of the defined configured model based on a simulation result of the discrete events simulation section and data on soft error rates in the attribute information.
