Testing and Control in Embedded Software and at Physical Interfaces
Development of Measurement, Monitoring, and Control Systems
Modular test benches for the development of electric drive systems
Synchronous testing and control within embedded software and at physical interfaces.
The behavior of variables in embedded systems is difficult to track.
Our open-source middleware, es:prot, can be integrated into the C code of any microcontroller, making runtime variables visible as measured values in real time and writable as control values.
Thanks to the software-based testing and configuration approach, there is no need for external debug or trace probes, symbol files, or execution pauses for data access.
Requirements for measurement setups change regularly.
es:mod is an open hardware platform for signal acquisition, processing, and control, designed to meet specific and evolving test requirements. The configurable system enables the synchronized acquisition, processing, and streaming of sensor signals, the control of actuators and power supplies, and the execution of user-defined edge logic. Users can utilize front-ends and software from our portfolio or integrate their own designs.
Software and hardware are closely integrated, but they are tested separately.
Cross-Domain Testing (CDT) displays runtime variables and physical measurement signals on a common timeline, thereby providing a comprehensive view of system behavior. This makes it possible to identify interdependencies across software and hardware and resolve them at runtime.
Which software behavior led to which physical problem? What effect does adjusting the parameters have?

Measure internal states of embedded systems
Only by taking measurements on the prototype is it possible to verify an embedded system, including its hardware and software. In many cases, this requires access to relevant data from the system’s internal states….

Continuous insight into runtime behavior
…while there are runtime analysis tools available, they cannot cover every possible scenario. It is therefore crucial to find the combination of tools best suited to the specific application.

Embedded Systems: From Concept to Market
Complex embedded projects often fail due to unclear requirements, a lack of experience, or insufficient development capacity. es:saar supports such projects from the initial requirements analysis through prototyping and validation all the way to market launch and production support.
We develop complete hardware and software systems: from power electronics and motor control systems to condition monitoring and specialized test and measurement systems.
We combine industrial experience with close ties to research in the field of drive technology.
Competence in testing electric drives and developing embedded systems
When requirements, protocols, and test specimens change, test benches must also be adapted. Anyone who then has to rebuild them loses time and money.
es:bench is based on the open, modular DAQ and control system es:mod. This allows you to avoid vendor lock-in and the need to build a new system when requirements change.
Finding the right control strategy for an electric drive is a complex task: sensor-based or sensorless, for existing or new motor families?
We support the process from the feasibility study through to commercial implementation. If necessary, the test bench is part of the development project.
Developing motor controllers and power electronics in-house is a complex process: not every topology is suitable for every drive. We develop motor controllers and power electronics that are truly compatible, ranging from classic Si/IGBT topologies to wide-bandgap designs based on SiC or GaN.
We coordinate hardware and software and can perform qualification using our own procedures.
We look forward to discussing your Embedded systems development. As a partner for corporations, SMEs, start-ups, and public research institutions, we support you at every stage.
