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

TLDR

A recently proposed nuclear reaction theory underpins the nuclear reaction database used in the NISES simulator. The authors review two types of simulators for analyzing cosmic ray neutron‑induced soft errors. They compare the neutron‑induced soft error simulator (NISES), which uses the new nuclear reaction database, with the simplified MBGR simulator based on a modified burst generation rate model. Both simulators accurately predict neutron‑induced SE rates, with MBGR offering faster estimates, while NISES provides broader coverage including charge‑collection, multi‑bit, and alpha‑induced SE analysis.

Abstract

The authors review two types of simulators for the analysis of cosmic ray neutron-induced soft errors (SEs). 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 simulator, 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 (SERs). MBGR actually provides an easier and quicker estimation of neutron-induced SER's than NISES. On the other hand, NISES covers more applications: it simulates neutron-induced charge collection, multiple-bit SE, and /spl alpha/-induced SE analysis.
