MES Summer School

Model-based development of embedded systems is a mature technology used to create technical software applications with high quality and efficiency. The MES Summer School is a 5-day training class on “Introduction to Model-based Software Development of Embedded Systems.” It gives a comprehensive introduction to this technology applied in the automotive and automation industry, among others. Starting from the elicitation and management of requirements through to the definition of architectures and the design of a model structure, the program provides an introduction to modeling. Particular attention will be paid to static and dynamic quality assurance methods to ensure that models from which high-quality software is sourced are suitable for safety-critical systems. By applying all relevant process steps during our hands-on sessions, you will face all the typical challenges of modeling safety-critical systems. This will prepare you for the application of relevant process steps to your own projects. The small training group size allowing individual supervision, the experienced training team, and a relaxed atmosphere will enable you to learn all that is necessary for safeguarding your safety-critical embedded software. To complete the picture, we will present recommendations of applicable standards in the field such as IEC 61508, ISO 26262, and ASPICE. The MES Summer School provides an easy entry to and a comprehensive overview of model-based development of embedded systems. You will learn to make use of all steps in practical exercises using the MES Test Manager (MTest), MES Model Examiner (MXAM), MES Model & Refactor (MoRe), and MES Quality Commander (MQC).

Target Audience

This training class is targeted at beginners to model-based development, including developers, testers, quality managers, project managers, and team leaders. The focus is on model-based development of safety-critical embedded software using MATLAB/Simulink in combination with Embedded Coder or dSPACE TargetLink. Only basic knowledge of modeling with Simulink and Stateflow is required.

Impressions of the MES Summer School 2019

Sun, great location, motivated participants - despite the scorching temperatures during the heatwave, we learnt a lot together and enjoyed the leisure program!

Costs & Conditions

For costs and conditions see the PDF.

A fee-based SAE Certificate of Competency can be obtained in this class by passing the evaluation test.

Leisure Program

We will organize a leisure program on three evenings for the participants of the MES Summer School. As part of the leisure program, we will spend an evening getting to know the Berlin neighborhood, enjoy two dinners at renowned eateries, and visit the Berlin TV Tower. An authentic experience!

Accommodation

We recommend staying in the hotel where the training class will take place, the Michelberger Hotel. When registering, you can order your hotel room, available from Sunday, June 13, 2021 to Friday, June 18, 2021 (4 or 5 nights). The price for one single room including breakfast is € 136 plus VAT (where applicable) per night. Michelberger Hotel is not just any hotel; it is an exceptional location bursting with creativity right in the heart of Berlin’s hip Friedrichshain-Kreuzberg district.
