MathWorks Simulink

ISO 26262 certified Model-in-the-Loop Tests

Introduction

What is Simulink?

Simulink (and Stateflow) from MathWorks have become the de-facto standard in the automotive industry for the development of embedded algorithm functions. The graphical language allows function developers to work on a higher and more intuitive abstraction level. This makes it easier to create, review, debug, and reuse the developed functions, which is important when considering their growing complexity.

Perfectly Integrated

Model-in-the-Loop (MIL) Test for Simulink with BTC EmbeddedPlatform

Although the strength of BTC EmbeddedPlatform lies in both managing models AND production code in one single test project, BTC EmbeddedPlatform can also create a test project for pure Simulink models. This is especially relevant during the early stages of a project, where code might not yet be available.

The creation of a Simulink test project is automated, with no manual interaction needed; BTC EmbeddedPlatform intelligently analyzes the architecture of the model to detect subsystems, ports, parameters, test points, data types and ranges. As we believe that a test tool should never touch or

modify the system-under-test, the test harness creation and execution happen on a temporary copy of the Simulink model. This makes it easy to manage the model and test data independently. The test harness creation happens in the background and requires no manual work.

Easily test on all subsystem Levels

Hierarchical Test Approach

Especially when working with large models, individual test cases often need to be run on a smaller subsystem or sub function within the model. 

But isolating that subsystem for test harness creation can require time-consuming and error-prone manual labor. And this often leads to additional models and artifacts which need to be stored, managed and maintained.

 With the powerful “hierarchical test approach” in BTC EmbeddedPlatform, all these problems are smoothly managed in the background. The needed test harness models are automatically generated “on-the-fly” from the original model, so that they don’t need to be stored or manually updated.

BTC TestComposer

Smart and powerful test authoring

In our experience, test cases are too often written in languages which were not designed for that purpose. Examples like Matlab, Python, Excel tables, or even C Code abound.

With BTC TestComposer, we provide a powerful editor for functional test cases directly within BTC EmbeddedTester BASE. BTC TestComposer knows all the details of the test architecture and protects users against invalid data entries. If enumerations are used, a drop-down menu is provided that allows direct selection of desired values.

Further features include a signal generator, a graphical viewer, flexible tolerance handling, and a formula editor, allowing us to calculate the value of a certain signal based on other variables. “Test Macros” and “Calibration Sets” can be used to specify and store reusable sequences for instantiation in multiple test cases. Test cases are executed directly within the editor and the results immediately visualized

Sandboxed environment

Smart Debugging

As modern Model-based development projects grow in complexity, the task of debugging failed test cases becomes increasingly difficult and time-consuming. Even more challenges emerge in situations where the function development and testing are separate, and performed by different people or teams. This leads to an important question: What is the most efficient way for a test engineer to provide his test scenario to development for further analysis?

BTC EmbeddedPlatform includes a unique debugging approach that generates self-contained sandboxes. These sandboxes contain a copy of the subsystem-under-test as well as the failed test case, including the corresponding calibration values. These sandboxes can be easily shared with colleagues or customers, making it easy to try out modifications without breaking the original files.s

certified

ISO 26262

BTC EmbeddedPlatform has been certified by German TÜV Süd as fit for usage in safety critical software development projects.

The certificate addresses different standards including IEC 61508-3:3010, ISO 26262, EN 50128, IEC 62304 as well as ISO 25119. For the automotive standard ISO 26262, the certificate is valid for all ASIL levels including ASIL D. As a verification tool, BTC EmbeddedTester has been classified with the highest tool confidence level of TCL 3.

We provide the certificate and the corresponding report to our customers free of charge upon request, which drmatically reduces or even eliminates any effort for tool qualification measures on the customer side.
