Architectures in Simulink & Stateflow – How to Manage Large Software Models


Date Language Location
May 6–7, 2020 English Berlin, Germany

Models are the core artifacts in automotive 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, rarely understandable, and the risk of errors due to unexpected behavior increases. The technical debt of the model demands proper countermeasures. This training class addresses deficits caused by large models and shows ways to overcome their risks.

Also available as an in-house training class worldwide on request.
In this case, our instructors can tailor the curriculum to meet your specific needs.

Pawel Malysz,

"The seminars provide insight and ideas on how to approach handling large software projects in a systematic way with useful suggestions and quantitative metrics."
