SafeTI functional safety: a tunable FMEDA for C2000 MCUs
With the ever-increasing focus on functional safety in industrial and automotive markets, product manufacturers are constantly challenged to minimise risks due to system malfunctions. Designing systems targeted at safety-critical applications involves adhering to a rigorous hardware development process, along with the implementation of safety mechanisms/ diagnostics to increase robustness against systematic and random hardware faults.
Safety analysis is an equally important step in the design of such systems to mitigate the risk of a violation of the functional safety goal due to hardware component malfunctions.
A failure mode, effects and diagnostic analysis (FMEDA) provides data on failure modes – data that’s required when quantifying risk reduction for the violation of a functional safety goal. An FMEDA is used in the development stage of a customer’s system and provides a detailed analysis of different failure modes, the associated effects of failure modes, diagnostics and the impact of any implemented diagnostics/safety mechanisms in terms of diagnostic coverage.
A Texas Instruments (TI) C2000 microcontroller (MCU)-based FMEDA comes with the added benefit of tunability, with features such as package failures in time (FIT) estimation, product function tailoring, safety mechanism tailoring and custom diagnostics, allowing customers to tune the FMEDA to the application-specific use of a TI MCU in their systems.
