Use of diversity for a fail-safe computing platform

Design diversity has been discussed in depth for at least three decades. There is a consensus on what benefit can be achieved and what cannot be achieved. In the light of modern computer systems, whose complexity is growing, and where increasingly automated tools are used for system generation, there is more potential for the successful use of diversity in its many forms. Diversity is even one of the most effective means to tolerate or detect some types of systematic faults. This potential can be shown especially well along the failure chain. A fail-safe computing platform serves as the reference system.
