Formal verification of automotive embedded software
Abstract
The ever-increasing complexity of automotive embedded systems and the need for safe advanced driver assistance systems (ADAS) represent a great challenge for car manufacturers. Furthermore, we expect that in the near future, authorities require a software certification in order to get convinced that ADAS are safe enough. Theoretical research and experience show that when using conventional design approaches it is impossible to guarantee high confidence to those systems. The way taken by some industries (e.g. aerospace, railway, nuclear) was by partially using formal verification techniques. In this paper, we first present a background of the formal verification techniques and how they can contribute to achieve the requirements of some safety standards. Next, we share our experience with the application of those techniques that seem to be mature enough to be used in an industrial context: Static analysis based on Abstract Interpretation, SMT-based software Model checking and Deductive proof. Finally, we make a detailed analysis about our experiments and propose an approach introducing formal methods into the development of automotive embedded software.
