Digital simulation of an automotive multiplexing wiring system

A digital simulator for an automotive multiplexing system has been developed and tested. The basic architecture and logical flow and block diagrams are described. Some results of the simulation are given. The contention scheme was found to work successfully in the simulator, and the outputs were found to be ordered in the same manner as expected by the requirements of the protocol. The network traffic and its effect on the latency index has also been studied. The simulator has provisions to incorporate alternate message retrial schemes and to test alternative strategies of the tasks. It is flexible enough so that the effects of noise and other nonideal phenomena can be incorporated. It is concluded that this simulator is a useful design/development tool due to its flexibility in testing alternative design strategies.<
