UPSET: Direct Ionization-induced SEE Rate Calculation
OverviewUPSET is a more complicated program that calculates the upset rate from the direct ionization of particles originating outside the spacecraft. UPSET assumes that each bit is stored in a microcircuit which has one continuously sensitive node. This node is surrounded by a sensitive region which is assumed to have the shape of a rectangular parallelepiped. To calculate the upset rate using UPSET, one must first use LET to create an integral LET spectrum. UPSET then integrates this spectrum over the differential distribution of pathlengths through the sensitive region of the one sensitive node in the microcircuit to obtain the SEU rate. InputsUPSET's input parameters are:
OutputsUPSET outputs upsets/(bit-sec) and upsets/(bit-day). Document Actions |
