In one of our latest articles, we highlighted the matter of test infrastructure in embedded systems. Regarding this article, we’d like to present a solution developed during the last few months for one of our clients.

The rig simulates and measures every possible analog and digital signal of the tested device and allows the testing of a marine automation device. This solution is based on PLC controllers from B&R company and VT System from Vector.

The project was created as a result of cooperation with Sponte-Elektro company.

Low-level testing is a kind of software testing, that is checking if each module, function, class, and method work correctly. It verifies the system functionality at the source code level, processor instructions, registers, memory, or hardware interface. Low-level tests are commonly used in embedded systems that are integrated with hardware and have limited resources.

The aim is to identify and eliminate logical, syntactical, or implementation bugs in the code before it’s integrated with other system components. Typically, low-level tests are carried out by developers creating and modifying the source code.

Summer internship kick-off!
Meet our first team: Kinga, Aleksandra, Mikołaj and Rostyslav.
This year is exceptional for us, due to the great interest. Over 20 interns will join our company during the summer.
It’s a real challenge, but we’re ready!

What distinguishes us is an individual approach. We’re one of the few companies that assign each intern to an individual mentor, ensuring that they can fully benefit from the mentors’ experience and knowledge. We believe an internship is not just a temporary relation with a company. It’s the first and most significant step toward professional growth. Our mentors’ are experienced professionals passionate about their work and sharing knowledge.

Today, embedded systems are used in a wide range of industries and devices we use, from smartphones through TV sets to cars. To assure the systems are of the highest quality, it is essential to test them and, for that to happen, create appropriate test environments. The test infrastructure team provides the essential elements for conducting tests as well as the tools for the management of the testing process itself. They are the key component both for testers, who need access to the right set of tools, as well as for the customer himself who expects reliable test results.

An important part of the test infrastructure are test environments. Testing of embedded systems is focused on the actual device, which may require various types of sensors, actuators or communication interfaces (used for interaction with the surroundings or other systems) in order to work properly. When testing particular components such as an ECU (Electronic Control Unit), for example, the test environment simulates input signals and allows the tester to check output signals produced by the device. Therefore, one of the primary tasks of the infrastructure department is finding solutions, which enable us to simulate the environment, in which the device under test will be used.
In our company, B&R X20 series, controllers, and Vector VT System devices are commonly used for this purpose, which the tester is operating using the Vector CANoe software. While the Vector VT System uses a build-in communication interface within CANoe, it was the test infrastructure team’s task to create a real-time communication solution with the other components.
