"数字逻辑电路设计-多功能数字钟实验详解"

The Multifunctional digital clock is a project that incorporates time setting, resetting, pause, hourly chime, and alarm functions. The entire experiment is based on the software design foundation of QuartusII 7.0, combined with the practical testing of Altera's Cyclone series programmable logic device toolkit. The development of the digital clock strictly follows the top-down design method, which saves the designers a considerable amount of time and effort due to its strong portability, logical compliance with general rules, and collaborative nature. The project demonstrates some degree of innovation and theoretical proof in the debounce circuit and the duration control of the buzzer ringing. Additionally, the organic packaging of each device during the design process ensures a clearer logical relationship in the circuit diagram. In today's society, digital clocks have become profitable commodities due to their essential role in daily life production. With the drive for profit, the design methods of digital clocks have significantly improved in terms of functionality and efficiency compared to the experimental product. Therefore, the purpose of this experiment is to provide designers with a comprehensive understanding of the process of digital logic circuit design and specific software usage methods. Through the utilization of programmable logic devices, debounce circuits, and a learner-centered design approach, this project offers valuable insights into the field of digital clock design.
