Fault-list collapsing for fault-injection experiments

Exfi

“…This module exploits the collapsing rules defined in Benso et al [1998], practically demonstrating how they can be implemented and how effective they really are.…”

An integrated HW and SW fault injection environment for real-time systems

“…A Fault Injection Support Board is exploited both during the Fault Injection experiment (mainly to activate the fault injection procedure), and during the preliminary phase aiming at gathering the information about the fault-free system behavior, which are required to implement a set of fault collapsing rules described in [7]. The board has been integrated into our Fault Injection environment, and is currently being used for the evaluation of the fault coverage parameters of some benchmark applications.…”

“…To include in the proposed Fault Injection system more sophisticated fault list generation capabilities, we exploited the FISB to implement the collapsing rules presented in [7] and briefly outlined in the following. They aim at avoiding the injection of those faults whose behavior can be foreseen a priori.…”

“…To address this issue, we defined a set of rules able to collapse an existing list of faults, avoiding the injection of those faults whose behavior can be foreseen a priori [7]. Unfortunately, the proposed rules require the availability of some information about the fault-free system behavior, which are often not easily obtainable.…”

Modelling and mitigation of soft-errors in CMOS processors

“…In the case of the second method, fault collapsing, a number of faults will be removed from the fault list based on the well-known fault collapsing techniques [Ben98]. Even though these two methods can decrease the elapsed CPU time of a simulation-based fault analysis, the check-point method is beneficiary only for rather simple designs.…”
