**Physical Model-based Development**

“Virtual” Prototyping through Model-based Design and Development plays an increasingly key role in system design, commissioning and testing. Increasing adoption of MBD and simulation Reduce prototyping cycles and costs Increase end-user functionality, quality, safety and reliability Deterministic, repeatable testing platform Connection to real components with virtual subsystems through Hardware-in-the-Loop (HIL) Testing is critical to this strategy Validation of subcomponents and/or controllers before integrating into the vehicle reduces errors and costs Validation of model against the real thing improves the whole process, dramatically reducing development cycles and time-to-market in the future Greater demand for greater model fidelity…
