Abstract
The evaluation of the gain in reliability of mult-iversion software is one of the key issues in the safety assessment of high integrity systems. Fault simulation has been proposed as a practical method to estimate diversity of multi-version software. This paper applies data-flow perturbation as an implementation of the fault injection technique to evaluate redundant systems under various conditions. A protection system is used as an example to illustrate the evaluation of software structural diversity, optimal selection of channel- pairs and the assessment of different designs.
