Cycle-Accurate LIN Network Modeling and Simulation

LIN (Local Interconnected Network) is a serial communications protocol that supports the control of mechatronic nodes in distributed automotive applications. This paper discusses LIN network modeling and simulation based on a token-based and event driven simulation platform. The complete LIN network features are modeled in the behavior level. The simulation is time-accurate and it provides system information, such as CPU load, bus utilization and message latency time. It can also simulate the scenarios such as network sleep and wakeup, switch event and error message. This LIN network simulation model can be integrated with CAN network simulation model for a complete vehicle network simulation.
