Toward nuclear SPICE – integrating IEC 61508, IEC 60880 and SPICE

Journal of Software: Evolution and Process, 2013
ABSTRACTInternational Organization for Standardization/International Electrotechnical Commission 15504 has been applied to several domains, where safety is one main characteristic for software and systems. Nuclear power industry is one of the most challenging domains, because of its extreme safety requirements.

Basic VHDL tests conforming to IEC 61508

2010 Seventh International Conference on Networked Sensing Systems (INSS), 2010
The development of embedded sensing applications based on integrated circuits leads to ever-growing complexity of VHDL-code and requires sophisticated testability to achieve high diagnostic coverage. The norm IEC 61508 provides a set of requirements for the implementation of safety-related software.

Integration according to IEC 61508

IEE Seminar Programmable Electronics and Safety Systems: Issues, Standards and Practical Aspects, 2002
Integration according to IEC 61508 is the process of providing an engineered safety-related solution, usually comprising 3rd party subsystems to the all embracing risk graded requirements, of the International Safety Standard IEC 61508. The systems integrator may include all or some of the subsystems that comprise an overall solution but this ...

Introduction and Revision of IEC 61508

2010
Over the past twenty-five years there have been a number of initiatives worldwide to develop guidelines and standards to enable the safe exploitation of programmable electronic systems used for safety applications. In the context of industrial applications (to distinguish from aerospace and military applications) a major initiative has been focused on ...

Prerequisites for IEC 61508 application

IEE Seminar Programmable Electronics and Safety Systems: Issues, Standards and Practical Aspects, 2002
Experience indicates that properly applied, IEC 61508 can lead to significant economic and safety benefits for user organisations. To apply the standard correctly requires judgement, competency and planning. A number of projects have had significant problems with applying the standard that can be traced to poor understanding and inadequate preparation.

Probability of Failure on Demand in IEC 61508

2004
This paper presents a new and explicit approach for estimation of average Probability of Failure to perform its design function on Demand (PFD), based on the expectations of fault duration / repair time in accordance with IEC 61508. From a practical viewpoint, the formula for estimation of PFD of the negligible Mean Time To Repair (MTTR) configuration ...

Research of CPU Functional Safety Based on IEC 61508

Proceedings of the 2nd International Conference on Artificial Intelligence and Advanced Manufacture, 2020
Central Processing Unit (CPU), as one of the core devices in electronic equipment, whether it can operate safely and reliably directly affects the safety of the entire electronic equipment. However, the electronic equipment manufacturers concern much more about the functional safety of System on Chip (SoC), for the functional safety of the CPU there is

How to profit from IEC 61508

Computing and Control Engineering, 2004
When we say that safety can contribute positively to the bottom line, we're not talking about safety consultancies but of companies whose operations pose potential dangers to health, safety, assets and the environment. these companies can profit from IEC 61508.

IEC 61508 and IEC 61511 assessments - some lessons learned

4th IET International Conference on Systems Safety 2009. Incorporating the SaRS Annual Conference, 2009
In recent years we have conducted about 25 assessments using IEC 61508 or IEC 61511, working mainly to Safety Integrity Level (SIL) 2, but on some occasions to SIL 3. In this paper we present some of the lessons we have learned and offer advice to those seeking certification for components, systems or generic process capability. We cover the three main
