Error Propagation Analysis (EPA) is a technique forunderstanding how errors affect a program's execution and resultin program failures. For this purpose, EPA usually compares thetraces of a fault-free (golden) run with those from a faulty run ofthe program. This makes existing EPA approaches brittle for multithreadedprograms, which do not typically have a deterministicgolden run. In this paper, we...
The automotive safety standard ISO 26262 strongly recommends the use of fault injection (FI) for the assessment of safety mechanisms that typically span composite dependability and real-time operations. However, with the standard providing very limited guidance on the actual design, implementation and execution of FI experiments, most AUTOSAR FI approaches use standard fault models (e.g., bit flips...
Following the design and in-lab testing of software, the evaluation of its resilience to actual operational perturbations in the field is a key validation need. Software-implemented fault injection (SWIFI) is a widely used approach for evaluating the robustness of software components. Recent research [24, 18] indicates that the selection of the applied fault model has considerable influence on the...
