JUST SIMPLIFY: Clone Detection for Simulink Controller Models

Author: Dr. Elke Salecker (Model Engineering Solutions GmbH), Dr. Ingo Stürmer (Model Engineering Solutions GmbH)
Published: SAE 2016 World Congress and Exhibition (online April 5, 2016)

Huge Simulink controller models often consists of (almost) identical subsystems, very often resulting from copy-and-paste operations and only slight adaptation of the subsystems by the model engineer. Although this “copy-and-paste” approach might help to achieve initial results very fast, in the long-run such subsystem clones can create considerable problems. Like code clones, model clones increase the effort for testing and maintenance. Model clones also tend to influence the code efficiency and code quality in a negative way in case the Simulink model is used as a basis for code generation. JUST SIMPLIFY is an approach for detecting model clones in a Simulink model automatically based on model metrics calculations. This approach has been implemented in our model metrics and complexity measurement tool M-XRAY. JUST SIMPLIFY allows reducing the effort for model refactoring by avoiding time consuming manual search for model clones. As a result, the effort for testing and for maintaining models can be reduced and the code quality can be improved significantly.


Managing an ISO 26262 Safety Case: A Software System Perspective

Author: Dr. Heiko Dörr (Model Engineering Solutions GmbH), Dr. Ingo Stürmer (Model Engineering Solutions GmbH)
Published: SAE 2016 World Congress and Exhibition (online April 5, 2016)

A key component of developing a safety-critical automotive system in compliance with ISO 26262 is developing what is known as the safety case. This delivery justifies that the system is free from unreasonable risk and that the safety requirements are complete and satisfied according to evidence from ISO 26262 work products. However, the standard provides neither practical guidance on how the safety case should be developed, nor how the safety argument should be evaluated in the functional safety assessment process.


Distributed Development of Large-Scale Model-Based Designs in Compliance with ISO 26262

Author: Dr. Ulrich Eisemann (dSPACE GmbH), Dr. Elke Salecker (Model Engineering Solutions GmbH), Dr. Ingo Stürmer (Model Engineering Solutions GmbH)
Published: SAE 2014 World Congress and Exhibition (online April 1, 2014)

The intent of this paper is threefold. Firstly, we summarize those requirements of ISO 26262 that are relevant for developing complex software in a distributed environment. Secondly, we provide best practices for distributed development of large-scale controllers with MATLAB, Simulink, and TargetLink in compliance with ISO 26262. We address topics such as functional partitioning of complex units, defining and using interfaces consistently, avoiding long processing times during code generation, as well as aspects of testing and software integration. Finally, we demonstrate how to apply model metrics to deal with Simulink model complexity and show how complexity can be improved.


Process for Functional Safety

Published: dSPACE Magazine 2013/01, July 2013, pp. 12-19

The Siemens Drive Technologies Division has added modelbased development to their classic software development process for implementing safety-critical vehicle functions. With the support of dSPACE TargetLink Strategic Partner, Model Engineering Solutions GmbH, Siemens Drive Technologies defined a process on the basis of dSPACE TargetLink that satisfies the requirements of ISO 26262 (Road Vehicles – Functional Safety).
