Objectivies and Approach

The objective of the action is to extend and integrate techniques and tools developed independently for testing and evaluating fault tolerance in computing systems, especially those used in real time safety critical systems such as automotive, aerospace and nuclear applications.

The work builds on European activities using physical fault injection techniques and American activities using fault simulation models.

European links: ESPRIT BRA project PDCS2 (6362), LTR project DeVa (20072), project GUARDS (20716).

Progress and Results

A framework for the development of a software-based fault injection tool for validation of software fault tolerant techniques under hardware faults has been defined. Work is in progress on the experimental assesment of the MARS architecture by means of physical and software implemented fault injection.

Information Dissemination Activities and/or Exploitation

Results of the work within FIEF have been presented at international conferences and published in scientific journals. (The list of publications can be requested from the coordinator.)
