The development of mixed-criticality systems that integrate applications of different criticality levels (safety, security, real-time and non real-time) can provide multiple benefits such as product cost-size-weight reduction, reliability increase and scalability. However, the integration of applications of different levels of criticality leads to several challenges with respect to safety certification standards. This paper defines a safety certification strategy for IEC-61508 compliant industrial mixed-criticality systems based on multicore partitioning. The final objective is the certification of a wind-turbine mixed-criticality control system according to IEC-61508 and ISO-13849 industrial safety standards.
