Reliability evaluation is a critical task in computing systems. From one side, the results must be accurate enough not to under-or over-estimate the overall system reliability (thus either resulting in a non-reliable system, or a system for which too expensive solutions have been adopted). On the other side, the time required for the analysis should be kept at the minimum. This paper presents some...
One of the consequence of the scaling down of latest technologies, is that digital circuits are more prone to be affected by faults caused by physical manufacturing defects, environmental perturbations (e.g., radiations, electromagnetic interference), or aging-related phenomena. Understanding the behavior of the whole system in the presence of faults affecting digital circuits is crucial for designing...
This paper describes the joint effort of the two FP7 EU projects CLERECO and MoRV toward the definition of an extended reliability information exchange format able to manage reliability information for the full system stack, from technology up to the software level. The paper starts from the RIIF language initiative, proposing a set of new features to improve the expression power of the language and...
Reliability evaluation is a high costly process that is mainly carried out through fault injection or by means of analytical techniques. While the analytical techniques are fast but inaccurate, the fault injection is more accurate but extremely time consuming. This paper presents an hybrid approach combining analytical and fault injection techniques in order to evaluate the reliability of a computing...
Developing new methods to evaluate the software reliability in an early design stage of the system can save the design costs and efforts, and will positively impact the product time-to-market. In this paper, we propose a novel fault injection technique to evaluate the reliability of a computing system running a software at early design stage where the hardware architecture is not completely defined...
Developing new methods to evaluate the software reliability in an early design stage of the system can save the design costs and efforts, and will positively impact product time-to-market. This paper introduces a new approach to evaluate, at early design phase, the reliability of a computing system running a software. The approach can be used when the hardware architecture is not completely defined...
Nowadays, the scientific community is looking for ways to understand the effect of software execution on the reliability of a complex system when the hardware layer is unreliable. This paper proposes a statistical reliability analysis model able to estimate system reliability considering both the hardware and the software layer of a system. Bayesian Networks are employed to model hardware resources...
