This work proposes a methodology to diagnose radiation-induced faults in a microprocessor using the hardware trace infrastructure. The diagnosis capabilities of this approach are demonstrated for an ARM microprocessor under neutron and proton irradiation campaigns. The experimental results demonstrate that the execution status in the precise moment that the error occurred can be reconstructed, so that error diagnosis can be achieved.
