Challenges in validating safety critical embedded systems
In industries with the strictest regulatory requirements, V&V alone can amount to 70% of the total development effort.Regulations also often mandate that system development and V&V teams operate completely independently from one another, to prevent conflicts of interest arising.
In fact, V&V can easily account for the biggest chunk of effort in the development of safety-critical systems.
Regulatory standards are increasingly important for complex high-assurance applications.
Some of these standards have been established for years, while others are just now emerging in key industries.
This paper outlines challenges in safety-critical embedded systems in addressing system-level faults that are currently discovered late in the development life cycle.
We then discuss an architecture-centric approach to model-based engineering, i.e., to complement the validation of systems with analysis of different operational quality aspects from an architecture model.
