"基于CPLD的交通信号灯设计：Verilog语言实现"

The design of traffic lights based on CPLD aims to effectively solve the time allocation problem for both pedestrian and vehicle traffic. It provides efficient and orderly services through the display and intelligent control functions of traffic lights, allowing people to participate in traffic activities in an organized manner. During nighttime when vehicle traffic is relatively low, the use of flashing yellow lights serves as a warning for drivers to slow down and proceed with caution, minimizing unnecessary waiting time and preventing time wastage. Verilog, as a hardware description language, is widely used in circuit design and can be implemented through various devices. Designing a traffic light control system using Verilog programming method ensures smooth traffic flow on roads, highlighting the language's good readability, portability, and ease of understanding. The design is completed through synthesis and simulation demonstration using Quartus II. Once the program is downloaded to the CPLD chip, it can be interfaced with the actual traffic control system. Keywords: traffic lights; CPLD; Verilog language; nighttime scenarios; Quartus II. In conclusion, the development of traffic lights under CPLD based designs offers a practical solution for efficient traffic management. By utilizing Verilog language and Quartus II, the system ensures seamless operation and easy integration with existing traffic control systems. This design not only enhances traffic efficiency but also promotes safety and orderliness in transportation systems.
