Smart automotive systems are moving towards being autonomous and are expected to detect and control failures with very minimal or few times no human intervention. Since, hardware and software complexity of systems in general is expected to grow at least by a factor 20 in the next few years; an increased risk of failure has to be addressed with utmost importance and urgency. This tutorial will introduce the challenges of the next generation ADAS (Advanced Driver Assistance Systems) and AV (Autonomous Vehicle) platforms and present details on the connectivity and sensor integration to the automobile system use case. Further, the tutorial provides reference and details on the road vehicle safety standards – ISO 26262, to ensure that standardized functional safety requirements for road vehicles and ISO 21448 Safety of Intended Functionality (SOTIF), for addressing of risks due to hazards resulting from functional insufficiencies of the intended functionality or by reasonably foreseeable misuse by persons. Next, the tutorial establishes the importance of the Responsibility Sensitive Safety (RSS) concept which builds a formal foundation that sets all aspects of human judgment in the context of driving with the goal of setting a “seal of safety” for autonomous vehicle. This tutorial will also include a discussion on architecture models for specifying and designing fault tolerant systems and will also describe the relationships with other disciplines such as Test, Reliability and Security. Finally, conclude with trends around designing for safety.


  • Riccardo Mariani

    Intel Fellow and Chief Functional Safety Technologist Riccardo Mariani is widely recognized as an expert in functional safety and integrated circuit reliability. In his current role as chief functional safety technologist at Intel Corporation, he oversees strategies and technologies for IoT applications that require functional safety, high reliability and performance, such as autonomous driving, transportation and industrial systems. Mariani spent the bulk of his career as CTO of Yogitech, an industry leader in functional safety technologies. Before co-founding the Italian company in 2000, he was technical director at Aurelia Microelettronica, where his responsibilities included leading high-reliability topics in projects with CERN in Geneva. A prolific author and respected inventor in the functional safety field, Mariani has contributed to multiple industry standards efforts throughout his career, including leading the ISO 26262-11 part specific to semiconductors. He has also won the SGS-Thomson Award and the Enrico Denoth Award for his engineering achievements. He holds a bachelor’s degree in electronic engineering and a Ph.D. in microelectronics from the University of Pisa in Italy. He has also appointed as the VP IEEE Computer Society 2019 for standardization efforts.
