Functional Safety standards like ISO 26262 require a detailed analysis of the dependability of components subjected to perturbations. Radiation testing or even much more abstract RTL fault injection campaigns are costly and complex to set up especially for SoCs and Cyber Physical Systems (CPSs) comprising intertwined hardware and software. Moreover, some approaches are only applicable at the very end of the development cycle, making potential iterations difficult when market pressure and cost reduction are paramount. In this tutorial, we present a summary of classical state-of-the-art approaches, then alternative approaches for the dependability analysis that can give an early yet accurate estimation of the safety or security characteristics of HW-SW systems. Designers can rely on these tools to identify issues in their design to be addressed by protection mechanisms, ensuring that system dependability constraints are met with limited risk when subjected later to usual fault injections and to e.g., radiation testing or laser attacks for certification.
