Executing Model-based Software Development for Embedded I4.0 Devices Properly

Fabian Burzlaff, Christian Bartelt, Steffen Jacobs
2018 Modellierung  
In this paper, we introduce a tool-based software engineering approach that puts models back at the core of embedded system development.  ...  At the moment, traditional engineering processes for embedded systems generate communication interfaces from software. This stands in stark contrast to componentbased software engineering approaches.  ...  In the context of V-Model XT, the process is as follows: As soon as the project scope is fixed (see left side of Figure 3 ), the development of hardware and software components is started.  ...

Design and validation of feature-based process model tailoring

Daniela Costache, Georg Kalus, Marco Kuhrmann
2011 Proceedings of the 19th ACM SIGSOFT symposium and the 13th European conference on Foundations of software engineering - SIGSOFT/FSE '11  
In this paper we present a tool for visual modeling and validation of process model tailoring based on feature models using the SE Book of T-Systems as an example.  ...  The tool is based on a domain-specific language that represents the process model. It leverages the semantics of feature models to provide an easy-to-use editor for tailoring-enabled process models.  ...  It uses a feature model known from Software Product Line engineering [2] to describe the mandatory and the variable parts of the process model.  ...
