Conference paper (peer-reviewed)abstract
- This paper presents the results of an extensive experimental study of bit-flip errors in instruction set architecture registers and main memory locations. Comprising more than two million fault injection experiments conducted with thirteen benchmark programs, the study provides insights on whether it is necessary to consider double bit-flip errors in dependability benchmarking experiments. The results show that the proportion of silent data corruptions in the program output, is almost the same for single and double bit errors. In addition, we present detailed statistics about the error sensitivity of different target registers and memory locations, including bit positions within registers and memory words. These show that the error sensitivity varies significantly between different bit positions and registers. An important observation is that injections in certain bit positions always have the same impact regardless of when the error is injected.

Conference paper (peer-reviewed)abstract
- Functional safety is becoming increasingly important in the automotive industry to deal with the growing reliance on the electrical and/or electronic (E/E) systems and the associated complexities. The introduction of ISO 26262, a new standard for functional safety in road vehicles, has made it even more important to adopt a systematic approach of evaluating functional safety. However, standard assessment methods of benchmarking functional safety of automotive systems are not available as of today. This is where the BeSafe (Benchmarking of Functional Safety) project comes into the picture. BeSafe project aims to lay the foundation for benchmarking functional safety of automotive E/E systems. In this paper, we present a brief overview of the project along with the benchmark targets that we have identified as relevant for the automotive industry, assuming three abstraction layers (model, software, hardware). We then define and discuss a set of benchmark measures. Next, we propose a benchmark framework encompassing fault/error models, methods and the required tool support. This paper primarily focuses on functional safety benchmarking from the Safety Element out of Context (SEooC) viewpoint. Finally, we present some preliminary results and highlight potential future works.

Conference paper (peer-reviewed)abstract
- This paper presents the results of an extensive fault injection study of the impact of processor faults that manifest as bit flip errors in instruction set architecture registers and main memory locations. The aim is to investigate if bit errors that propagate to the source registers or memory locations of a given class of machine instructions have a similar probability of generating undetected value failures (i.e., silent data corruptions) for different programs. The results show a fairly large variation in the error sensitivity over different programs for all classes of machine instructions, which indicates that the effectiveness of error mitigation techniques that target specific machine instructions may vary significantly for different programs.
