Increasing system reliability

Self-validation of complex electronic systems using grey box models

Research News /

When you mix together black and white, you get gray — and with it, a new method that should allow complex electronic systems to monitor themselves. Using so-called grey box models, on which researchers at the Fraunhofer Institute for Reliability and Microintegration IZM are working, it will be possible to detect signs of wear or manipulation in electronic systems at an early stage, before an actual failure occurs. The new process is being initially developed and tested for safety-critical applications in the automotive and rail sectors. The basic principle can, however, be transferred to many more application areas.
