Simulation technologies for cosmic ray neutron-induced soft errors: Modelsand simulation systems

The authors review two types of simulators for the analysis of cosmic ray n eutron-induced soft errors (SE's). One of them is the neutron-induced soft error simulator (NISES), A recently proposed nuclear reaction theory forms the foundation for the nuclear reaction database used in NISES. The other s imulator, the simplified simulator MBGR, is based on a modified version of the burst generation rate (BGR) model. Both simulators accurately simulate neutron-induced SE rates (SER's), MBGR actually provides an easier and quic ker estimation of neutron-induced SER's than NISES, On the other hand, NISE S covers more applications: it simulates neutron-induced charge collection, multiple-bit SE, and alpha-induced SE analysis.
