In order to develop a better understanding of the application of Scrum to IEC61508 certifiable software, we assessed the standard to see how Scrum could conform. Each section of part 3 of the standard was assigned one of the categories: (1) “OK” – no modification needed to Scrum or IEC61508, (2) “?” – need to be discussed, (3) “Not OK” – need adaptation of Scrum Based on our assessment we propo...

Dijitalleşme ve endüstri 4.0’ın etkisi ile gündelik hayatımızda kullandığımız birçok sistemde artık daha fazla elektronik programlanabilir bileşen bulunmaktadır. Bu artan karmaşıklık beraberinde güvenlik riskini de açığa çıkartmıştır. İlgili sistemleri güvenli kılmak adına uluslararası camia standart regülasyon ortaya koymuştur. noktada IEC 61508 standardı güvenlikle ilgili sistemin hayata geçi...

In 2010, Rolf Spiker approached one of us with a query from a client concerning advisory material in IEC 61508 on the statistical evaluation of software. We realised that there is a dearth of practical guidance for those who wish to evaluate critical software statistically. We believe statistical evaluation of software is an increasingly important assurance technique. We commence with a brief i...

Modern automotive and industrial designs often contain fifty or more micro-controllers and multiple CAN networks interconnect these electronic units [1-3]: therefore, enhancement in reliability, reduction of verification and validation costs, saving in test time are crucial points to deliver any high quality product, especially in automotive, as also required by the IEC-61508 normative for safe...

Assurance (Security and Safety) Case is an approach to prove critical systems and software compliance with security and safety requirements. We propose an advanced framework named as Assurance Case Driven Design (AC DD) to improve cost-effectiveness of certification and licensing processes. AC DD is based on Claim-Argument-Evidence-Criteria (CAEC) notation and Development-Verification&Validatio...

This paper presents an analysis of the impact of the Development Assurance Level (DAL) or Safety Integrity Level (SIL) on the system activities in various application domains represented in the CG2E “Club des Grandes Entreprises en Embarqué”) and specially on the dependability, safety norms and standards working group. The main goals of this paper are to: • Analyse the impact in each applicatio...

For the use of Field Programmable Gate Array (FPGA) in safety-related applications, Hardware Description Languages (HDL) are used to define the digital function. The process of such development is presented in the international standard IEC 61508, which introduces guidelines and calculations to achieve a specific Safety Integrity Level (SIL). However, it is not concerning the estimation and cal...
