The Time-Triggered Ethernet(TTE) synchronization strategy ensures high-quality synchronization.The research on modeling and simulation of TTE synchronization strategy is presented in this paper.We proposed a modular approach for modeling and simulation of TTE protocol,constructed a clock model with linear drift,modeled the protocol state machine and the clock synchronization as discrete events.Through the modeling and simulation,the performance of TTE synchronization under typical configuration parameters was studied.The simulation result verified that the clocks of TTE devices could be synchronized within microseconds.
