Virtual Stress-Testing a Digital Twin of a Motor Control Platform using Dynamic Fault-injection

Replacing a core component of an industrial embedded systems usually requires huge efforts regarding verification and validation of the new setup. Especially replacing the MCU normally entails significant changes to the hardware/software interface design and the verification process, possibly including the purchase of expensive design IP and verification IP for the specific component. To achieve a shift-left of the system verification, a Virtual Prototype of the system is created to detect possible issues as early as possible during this redesign process long before the real hardware is available. In this way, an early feasibility study can be started independent from the hardware redesign process. The use-case presented here is a system redesign of a Motor Control Platform where an existing microcontroller (MCU) is to be replaced by a new RISC-V core.
