Abstract

The design and the development of dependable fault-tolerant computer systems require an accompanying test and validation method to obtain confidence in the fault-tolerance mechanisms. An experimental validation method especially suited for the assessment of fault-tolerance mechanisms is fault injection. This paper makes two contributions. First, software-implemented fault injection is used in a series of experiments to validate the fail-silence assumption of the processing nodes in the MAintainable Real-time System (MARS). Second, the results of the software-implemented fault injection experiments are compared to the results obtained by three physical fault injection techniques---heavy-ion radiation, electro-magnetic interferences, and pin-level fault injection---to identify similarities and differences in the error sets generated by these techniques.
