CHIP HARDWARE-IN-THE-LOOP SIMULATION (CHILS) - EMBEDDING MICROCONTROLLER HARDWARE IN SIMULATION

摘要

Simulation is an important method in the design and validation process of complex hardware/software systems like electronic control units (ECU) for automotive applications. Modelling of such systems is a trade-off between high speed, high accuracy and low effort. It is easy to create a model covering two of these three attributes but it is nearly impossible to build high speed and high accuracy models spending only low effort.rnMany complex hardware/software systems are a combination of existing parts like microcontrollers, memory subsystems, interconnect structures, I/O and hardware accelerators. The possibility to embed a real microcontroller (MC) hardware into a system simulation of a larger technical context would be a great benefit. The MC itself can run with high speed and full accuracy. The challenge is to embed the MC into the simulation environment so it is transparent for the system simulation whether it is a simulated or a real MC. In this paper, we present a new solution called CHILS to fulfill this requirement.
