This paper addresses issues relating to the suitability of using automated code generation(ACG) technologies for the development of real-time, safety-critical systems. This researchexplored the characteristics of model-based software development methodologies and the automatedcode generation tools that support them. Specifically, data related to the engineeringchallenges, skills, and effort associated with ACG practices and technologies were collectedas part of a case study. Characteristics such as the generated code’s organization, size, readability,traceability to model, real-time constructs, and exception handling were identified. Inaddition, the case study involved software engineering practices that incorporate integratedanalysis and design iterations throughout a model-based development process. The researchinvestigated both the static and dynamic characteristics of the selected techniques and tools,identified characteristics of ACG tools with potential impact on safety, and considered thesemantic consistency between representations.
