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 […]
Interview: How does a Model Checker work?
Model Checking is part of the Formal Methods which address formal specification, formal development, formal verification and theorem provers. Model Checking belongs to the formal verification and provides a complete mathematical proof to verify your system-under-test. BTC EmbeddedPlatform uses the model checking technology for structural test data generation to achieve full code coverage, for formal […]
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 from Simulink. 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” […]
