Riassunto analitico
Nowadays there is a big growth of electronic components used to guarantee safety and reliability in many life-critical types of environment. In the automotive field safety is one of the main issues. Norms for functional safety such as IEC 61508 have not been ideated to address specifically automotive electric and electronic systems. ISO 26262 is currently under development to fill this gap. In this context, fault simulation is a powerful tool to understand the level of immunity from faults of E/E systems. The off the self simulators are not built to address the problem of functional safety, there are some limitations to perform permanent fault analysis and there is not the possibility to run transient fault analysis. This document describes a new environment to perform fault injection with the particular intent to address functional safety to help the development of E/E systems in compliance with ISO 26262. This new fault simulator differs from the off the shelf solutions by way of the level of configurability it allows, especially in relation to observation points that can be used. As the system is based on a standard logic simulator, the verification environment may also incorporate checkers as well as allow the possibility of using assertions.
