Deriving Safety Cases for the Formal Safety Certification of Automatically Generated Code

We present an approach to systematically derive safety cases for automatically generated code from information collected during a formal, Hoare-style safety certification of the code. We use a generic safety case that is instantiated with respect to the certified safety property and the program. It is complemented by a static system safety case that argues the safety of the framework itself, in...

Annotation Inference for Safety Certification of Automatically Generated Code

ed Control FlowGraphs. The algorithm uses abstracted control flow graphs (CFGs), in which code fragments matching specific patterns are collapsed into individual nodes. Since the patterns can depend on the variables, separate abstracted CFGs must be constructed for

Building Heterogeneous Safety Cases for Automatically Generated Code

Safety cases provide a mechanism for representing evidence-based arguments that a system is acceptably safe to operate in its intended context. We show how we can automatically combine diverse types of information from heterogeneous sources into a single integrated safety case for a system implemented using automatically generated software. The core argument structure of the safety case is gene...

Deriving Safety Cases from Automatically Constructed Proofs

Formal proofs provide detailed justification for the validity of claims and are widely used in formal software development methods. However, they are often complex and difficult to understand, because the formalism in which they are constructed and encoded is usually machine-oriented, and they may also be based on assumptions that are not justified. This causes concerns about the trustworthines...

Automatically Generated Safety Mechanisms from Semi-Formal Software Safety Requirements

Today’s automobiles incorporate a great number of functions that are realized by software. An increasing number of safety-critical functions also follow this trend. For the development of such functions, the ISO 26262 demands a number of additional steps to be performed compared to common software engineering activities. We address some of these demands with means to semi-formally express softw...
