Field Programmable Gate Arrays (FPGAs) are
sensitive to upsets that occur in aerospace. Drastic device
shrinkage, power supply reduction, and increasing operating
speeds significantly reduce noise margins and thus reliability;
hence the rate of transient and intermittent faults is increased in
modern electronic systems. Improving the fault tolerance of
reconfigurable devices is increasingly important in domains
ranging from mission critical embedded applications to the use of
FPGAs in physically remote environments such as satellites. This
paper shows the sources of radiation in the space and their effects
on FPGAs. Also, main mitigation techniques used to recover
from faults in FPGAs are explored. |
