FlexRay is a new standard of network communication system which has been developed for future automotive applications. It was devised by automotive manufacturers and semiconductor vendors. FlexRay provides a high speed serial communication, time triggered bus and fault tolerant communication between electronic devices for automotive applications. In this paper, FlexRay system is first designed using SDL (Specification and Description Language). For hardware implementation, FlexRay system is designed using Verilog HDL based on the SDL design result. The disigned system is synthesized using Synopsys Design Compiler with the Hynix 0.18 ?m cell library. For constructing a FlexRay communication network, the active is used since active star systems can provide high speed data transmission up to 10 Mbps. The performance of the active star network is tested using one transmitter node and two receiver nodes.
