- Fault Injection: the group developed and practically experimented a number of new techniques for devising and implementing effective Fault Injection environments. The main target of this activities have been embedded low-cost microprocessor-based systems. Several Fault Injection approaches have been investigated, based on simulation, software techniques, and hardware-supported ones. Low-cost, high-portability, and low intrusiveness have been the main goals of the proposed approaches. Special attention has been devoted to systems based on Motorola microcontrollers, by exploiting the BDM feature they provide.
- Fault List Generation and Collapsing: when Fault Injection is exploited for assessing the reliability and safety of a microprocessor-based system, or for debugging its fault-tolerance features, the generation of the list of faults to be considered is a major issue. The choice of the list content seriously affects both the meaningfulness of the results, and the time required to obtain them. In this area, the group developed a method for collapsing an existing list of faults by removing faults, whose behavior can be a priori foreseen.
- Software techniques for Soft-Error Detection: the need for low-cost safe systems, and the increasing concern for the reliability of deeply integrated circuits, which are more and more sensible to soft-errors, pushed the group towards the development of a new technique allowing the automatic transformation of high-level code, so that it is able to detect possible errors affecting data and code, and arising in memory, caches, registers, or even during bus transmission.
