Abstract: the communication bandwidth, flexibility and bit rate has been a serious issue for the serial communication protocols like Controller Area Network (CAN), Time-Triggered CAN (TT-CAN) and Byte-flight in implementing real time applications. The lack of a suitable networking scheme that could handle the requirements such as more sophisticated safety systems and advanced networking application leads to the development of the new protocol, the Flex ray. The main target for the new protocol is the growing demand for massive and complex data exchange in the environment where real time requirements are critical. The Flex-Ray is a new time-triggered protocol which is designed to provide large bunches of data to be exchanged in real-time with high dependability between electronic control units, sensors and actuators installed in a vehicle .The Flex ray node consists of a host, communication controller and a bus driver in which the communication Controller (CC) is an electronic component in a node which is responsible for implementing the protocol aspects of the Flex ray communications system. Flex ray communication controller (CC) is the core of the Flex ray protocol specification. It performs all communication tasks such as transmission and reception of messages in a Time-Triggered protocol (TTP) cluster. The purpose of the the introduced system is to generate a Flex ray protocol frame and the design of Flex ray protocol operational states with Finite State Machine(FSM).The work is coded by Verilog and simulated by Xilinx ISE 13.2.
