摘 要打铃器在我们生活很常见，在学校上下课提醒方面，打铃器必不可少。另外,在公司、工厂这些公告场合中,打铃器确实的不可或缺的工具,它能够按时提示人们时间,起到定时的作用。因此，本次设计的打铃器对我们的生活来说很实用，很有发展前景。70405
在本次设计中，我选用了基于FPGA的方法进行设计，芯片主要采用的是EP3C25F324C8器件。该芯片可以很好的控制时钟的调时、开关等等，易于操作，经过反复对比，该芯片却是最佳之选。
本次论文详细的介绍了整个设计流程及仿真的过程，对芯片和工具也做了一个详细的介绍，即特点和使用方法。另外对整体结构和系统的功能及原理做了一个概述，并说明了选题的目的及其发展前景。打铃器的应用正日益多元化，而我们的生活却越来越离不开它，因此，对打铃器多样化功能的研究具有很大的意义与前景。

The school bell device design based on FPGA
Abstract Ringer is very common in our daily life, in the school class remind, bell is essential. In addition, in factories and companies in the public, ringer indeed indispensable tool. It can on due presentation time people, play a role in the timing. Therefore, the bell of this design is very useful for our life.
In this design, I use the method based on FPGA design and chip mainly used is the device EP3C25F324C8, the chip can be very good control of the clock timing and start and stop, easy to operate, after repeated contrast, the chip is the best choice.
This paper detailed describes the process of design and Simulation of the process, the chip and tools also made a detailed introduction, that is, the characteristics and methods of use. In addition, the overall structure and function and principle of the system are summarized, and the purpose of the selected topic and its development prospects are also explained. Ringer application is increasingly persifying, and our life has become increasingly inseparable from it. Therefore, sparring bells for perse functions of research has great significance and prospect.
