Engineering Embedded Systems with the SPES Methodology
In the “Software Platform Embedded Systems” (SPES) research line, the SPES2020, SPES_XT, CReSt, SPEDiT and SpesML projects of more than 45 partners from science and industry have developed the foundations for a comprehensive methodological toolkit for the seamless model-based engineering of embedded systems.
Scientific studies have shown that the use of integrated model-based techniques, such as those developed in the SPES consortium, can significantly reduce product development costs (on average by 27% to 34%). The reason for this is that models with strong semantics and an engineering methodology based on them can avoid common problems such as incomplete or contradictory models. Analyses to ensure artefact quality and the automation of development tasks based on the semantics of the models contribute to the optimization of engineering.
It is extremely important for companies in German industry to get started with model-based development and thus the end-to-end digitalization of engineering. Only in this way can development times be reduced in order to continue to compete internationally in the future.
SPEDiT training material
The SPEDiT (Software Platform Embedded Systems Dissemination and Transfer) project has prepared learning materials in the form of practical tutorials that take into account the specific requirements and boundary conditions of the various stakeholders (e.g. different companies and people involved in the engineering process). For this purpose, multimedia learning courses (modules) were developed that are tailored to typical roles in the development process.
The learning courses are divided into multimedia learning units (blocks), which are prepared as SCORM packages (SCORM: Sharable Content Object Reference Model). SCORM packages can be executed in a browser or on a SCORM- enabled learning platform. In order to make the modules as self-sufficient as possible, the content of the learning units is in some cases contained in several modules (possibly with different learning objectives).
