Technology used in cars, aeroplanes and industrial robots is becoming increasingly complex. Can the software be extended? How does the system handle errors?
More and more companies are tasked with such questions. A simulation method, developed by researchers in Kaiserslautern, will provide a solution. With this, they verify in what combination hardware and software systems function correctly together.
In addition, the researchers can examine the reaction of systems critical for safety in the occurrence of errors. At the Cebit computer trade fair in Hannover, researchers will present their technology at the research stand of Federal State Rhineland-Palatinate (hall 6, stand C17).

Nowadays, cars comprise a multitude of hardware and software components: for example, if all functions correctly, a sensor on the wheel of a car will detect whether the wheels are locked or the car is sliding. At the same time, other sensors monitor whether the brakes are functional. Here, these systems communicate simultaneously with each other.
Software systems comprise a multitude of such components. Developers must examine whether they are compatible with each other. “This is becoming increasingly complex with new hardware and software”, explains Matthias Jung, doctoral student at the Microelectronic Systems Design Research Group, led by Professor Dr. Norbert Wehn at the University of Kaiserslautern. “There are countless possibilities to combine such systems. It must always be determined whether the technology will run smoothly with the desired requirements”.
Together with the colleagues of Dr. Thomas Kuhn from the Fraunhofer Institute for Experimental Software Engineering IESE, researchers at the High Performance Center Simulation- and Software-based Innovation have developed a process, which is dedicated to such issues. “With our simulation platform FERAL, we can already examine whether hardware and software components will function together during development”, explains Dr. Kuhn, Head of Embedded Software Engineering at Fraunhofer IESE. “FERAL” is the abbreviation for Fast Evaluation on Requirements and Architectural Level.
“We can calculate a vast range of scenarios with this, whether for existing systems or new versions”, Dr. Kuhn continues. “Furthermore, we can for example test software and hardware that does not yet even exist using our virtual platform”.
With the process, researchers can also detect possible errors that are built into the technology. “This makes this method interesting for virtual product development”, explains Matthias Jung. The researchers provide the system as a service to middle-sized companies and large corporations. The technology is especially important for testing embedded systems. These microcomputers, that interact with their technical surroundings, are built into a multitude of products, including cars, aeroplanes, smartphones, as well as pacemakers and dialysis machines. Moreover, researchers can examine the reaction of systems critical for safety - such as in aeroplanes and industrial production plants - with regard to the occurrence of errors.
The team led by Kuhn and Jung have already collaborated with clients from the commercial vehicles industry and plant construction sector. They will present FERAL at the Cebit, at the research stand of Federal State Rhineland-Palatinate.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
