AUTOSAR – When to use Client/Server or Sender/Receiver communication?
Introduction In AUTOSAR Classic, communication between software components is vital for building complex automotive systems. AUTOSAR provides various interfaces to facilitate communication and the two fundamental ones are AUTOSAR Sender-Receiver or Client-Server interfaces. Each interface type has distinct characteristics and attributes that make them suitable for different scenarios. In this article, we will present each […]
What you should now about testing variants
Creating different variants of a software component is an efficient way of reusing existing and developed features for different versions of a specific component or controller. Thus, testing variants is an ubiquitous task in the automotive industry that needs to be taken into account during testing. How are variants created in a Model-based Software development process? When […]
4 reasons to avoid writing test cases in Excel
I once heard someone say: “It’s impossible to develop a software tool that isn’t a competitor to Excel”. And that’s also true when it comes to the creation of test cases for testing embedded software. Over the past 20 years, Excel has been a very popular format and language to create, manage and store test […]
Why requirements are so important for your project
“What is the biggest challenge in projects?“ I asked that question during a coffee break at the 2022 MathWorks Automotive Conference in Stuttgart; I will share the answer I got in a minute. But first, what do you think the biggest challenge in embedded software development projects is? Quite often, we think that the biggest […]
Why Back-to-back testing is still needed for floating-point
Introduction When I started working at BTC Embedded Systems in 2014, floating-point was a rare topic in customer meetings and many control units supported fixed-point only. But since then, floating-point became more and more important and has fully arrived in the projects today. Back-to-back testing can be used for various use cases but the most […]
4 steps to not screw up Jenkins
Introduction During the last six years I have worked with many customers who used Jenkins as their central automation server for everything remotely related to software. In my previous role at BTC I spent much time setting up the complex Jenkins setup for BTC internal use. This meant covering multiple programming languages (Java, Matlab, C/C++, […]
Moving Automotive Embedded Software Development to the Cloud
I will spare you from a lengthy monolog on why a CI Pipeline that requires manually configured environments is fairly limited when it comes to scaling it out to other projects, other teams. I assume that you have felt the pain yourselves. There are different aspects to this topic including integrating with a cloud provider […]
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 AUTOSAR Code Replacement Library Routines at Ford Motor Company
The 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 be used […]
AUTOSAR – What is the Best Approach to Handle Reusable Code?
Component reuse is a common use case in any type of software and this is particularly true in automotive applications. Consider the equipment in the cars such as wheels, seats, doors, lights, clutches (e.g., in a dual-clutch transmission), and so on. They are controlled by software and as they exist by pairs, it makes sense […]
