Reliability & Safety

Many automotive functions are safety-critical, in particular chassis functions (steering, breaking, stability control …) and driver assist functions (adaptive cruise-control, lane-keep assist, lane-change assist …). Increasingly, safety-critical functions also appear in powertrain (e.g. thermal management of Li-Ion batteries) and body (power-windows / door-locks, keyless entry …).

The automotive safety standard ISO 26262 imposes strict timing requirements for failure-detection, error-correction and transitioning into a safe state. Symtavision understands the resulting architecture and timing challenges and supports our customers in designing and verifying solutions that meet ISO 26262 requirements from a timing perspective.

Symtavision specializes in particular on advanced safety-critical systems, including:

  • Highly integrated ECUs leading to mixed-criticality systems.
  • Multi-Core CPUs as a solution to increased performance while reducing chip cost, power consumption and size of ECUs.
  • Optimizing the allocation of functions to CPU cores to achieve the best performing architecture that also meets all safety requirements, including when to use lockstep, virtualization, and other partitioning techniques?
  • Optimizing the scheduling of tasks on CPU cores to achieve the best utilization while ensuring freedom from interference
  • How to best use timing monitoring and protection mechanisms (e.g. deadline monitoring, execution time monitoring)
