I. INTRODUCTION
All types of electronic systems can malfunction due to external factors. The main sources causing faults within electronic components are radiation, electromigration and electromagnetic interference. The evaluation of a fault- tolerant system is a complex task that requires the use of different levels of modeling. Compared with other possible approaches such as proving or analytical modeling, fault injection is particularly attractive.
Fault injection is a key requirement of functional safety standards like the Automotive ISO 26262 and is highly recommended during hardware integration tests to verify the completeness and correctness of the safety mechanisms
