Abstract
In this work we present a technology for dynamically introducing fault structures into digital twins without the need to change the virtual prototype model. The injection is done at the beginning of a simulation by dynamically rewiring the involved netlists. During the simulation on a real-time platform, faults can be activated or deactivated triggered by sequences, statistical effects or by events from the real world. In some cases the fault structures can even be auto-generated directly from a formal specification, which further automates the development process for safety-relevant systems. The approach is demonstrated at a SystemC/ SystemC AMS virtual prototype of a safety-critical sub-systems which runs on a dSPACE real-time hardware.
