The Design and Simulation of the Control System of Complex Traffic Light based on Verilog HDL
Abstract: This paper is based on Verilog HDL design and simulation of complex traffic light control system. The main task is to use the Verilog HDL language for traffic light control system design, implementation city complex cross the intersection in each direction of the steering control lights, turn signals responsible for controlling the direction of each state and the order of conversion. Finally, test modules and the simulation results are given. First, the paper describes the background and significance of research in complex traffic light control system. Regarding the subject on the object of both itself and the design language and Environment. Then the traffic light system has been designed according to the characteristics of the programming language and simulation environment. Finally, experimental and simulation software box completed the task. Which are mainly elaborated in this paper it is in the Verilog HDL environment from design, production to final realization of complex traffic light control system, detailed process, as well as the significance of this topic for research and experience, as well as problems encountered during the experiment .
