Summary:The authors address the dependability validation of fault-tolerant
computing systems and more specifically the validation of the
fault-tolerance mechanisms. Their approach is based on the use of fault
injection at the physical level on a hardware/software prototype of the
system considered. The place of this approach in a validation-directed
design process as well as its place with respect to related works on
fault injection are identified. The major requirements and problems
related to the development and application of a validation methodology
based on fault injection are presented and discussed. The proposed
methodology has been implemented through the realization of a general
physical-fault injection tool (MESSALINE) whose usefulness is
demonstrated by its application to the experimental validation of a
subsystem of a computerized interlocking system for railway control
applications
