Models are the core artifacts in software development. Over time – within a single development project or even across multiple evolution steps – models grow as they capture more and more functionality. As a result, models become hard to maintain, barely understandable, and the risk of errors increases due to unexpected behavior. The technical debt of the model demands proper countermeasures. This training class addresses deficits caused by large Simulink & Stateflow models and shows ways to overcome their risks.

Target Audience

This training class is targeted at modelers, developers, testers, quality managers, project managers, and team leaders, whose focus is model-based development of embedded software based on MATLAB/Simulink for serial projects.

Highlights

  • Basic concepts of software architectures
  • Assessing architectural design principles in models
  • Refactoring Simulink models
  • Layered application architectures
  • Representing architectures in models
