  The limits of previous methods promote us to design a new approach (named
PRESTAGE) to predict proton single event effect (SEE) cross-sections using
heavy-ion test data. To more realistically simulate the SEE mechanisms, we
adopt Geant4 and the location-dependent strategy to describe the physics
processes and the sensitivity of the device. Cross-sections predicted by
PRESTAGE for over twenty devices are compared with the measured data. Evidences
show that PRESTAGE can calculate not only single event upsets induced by proton
indirect ionization, but also direct ionization effects and single event
latch-ups. Most of the PRESTAGE calculated results agree with the experimental
data within a factor of 2-3.
