Simulink Interface Concepts
In Model-based Development and Embedded Software Engineering, the growing complexity requires concepts like modularization, ease of maintenance, or module reusability. In this context it is crucial to understand the interface in Simulink, which is defined by the data flow into and out of a subsystem. This blog article gives an overview about the different interfaces […]
Automatic Test of Ford Code Replacement Library Routines
What we haveThe Journey – from idea to solution It seems like every day more and more software teams are developing software in a model-based way, using Simulink models and auto-generated c-code… and Ford is no different. Many low-level math and interpolation routines have been developed by the central software team as libraries that can […]
3 Reasons to Consider Using a Floating-Point Model to Generate Fixed-Point Code
Despite the availability of fast processors with dedicated floating-point support, we still see many projects generating fixed-point code. The reason for this is not only the resource usage, but also the more transparent and predictable mathematical behavior. You can read more about this in our previous articles “What you should know about fixed-point” and “What […]
What You Should Know About Fixed-Point
Vocabulary: Floating-point? – Fixed-point? – Scaling? – Resolution? – LSB? Basically, we can distinguish between two kinds of datatypes in embedded code: Floating-point and Integer. An integer variable basically represents whole numbers and the value range is limited by the number of bits. For example, an (unsigned) 8bit Integer can represent 2^8=256 different values, by default ranging from […]
When and how to generate test cases automatically
The automatic generation of test cases has always been a controversial topic. While some people dream about stopping any manual test activities others say that test generation is not allowed. But who is right? Test Goals for test case generation Let’s have a quick look at the possible test goals for which we can generate […]
Modular Model-based Software Architecture for Efficient Unit and Integration Test
The use of model-based design to develop embedded software is well established in automotive projects but with the growing size and complexity of software, handling big sized model is often a challenge. Model-based design enables to easily craft a software application and from one step to another refine it, test it and generate the production […]
