Design of a Traffic Light System Using Verilog HDL

The topic of this paper relates to the design of a traffic light system through the hardware language Verilog HDL. It is developed in two parts: theoretic analysis of the operation modes; synthesis, simulation and implementation aspects of the control system based on the software ISE Design Suite of Xilinx. Three control modes are provided, namely: normal traffic; operation in increased traffic; emergency traffic. Based on the formulated regimes, a control program has been synthesized and a detailed simulation using Verilog HDL has been done. This study and the results obtained can be used in the design and practical application of different traffic light systems.
