Chapter 4 Functional Safety Validation

DOI: 10.1201/9781003391517-4

Functional safety requirements of automotive embedded systems include response time and reliability requirements. These two requirements must be met at the same time to ensure the automotive functional safety requirements. However, increasing reliability comes with extra response time overhead. This chapter addresses a method to get minimum response time possible while meeting reliability requirement. In recent years, a practical reliability requirement validation method was come up with that distributed the reliability requirement of the application to every single task to preassign reliability values to unallocated tasks. This chapter introduces two algorithms, namely non-fault ...
