基于EDA多功能音乐抢答器的设计

A Design of Multi-functional Music Responder Based on the EDA

本文设计一种以EDA技术作为开发手段的多路抢答系统。利用Altera公司的开发平台Quar-tus Ⅱ工具完成了编译、仿真,并下载到MAX Ⅱ系列的EPM570T144C5N器件进行测试。硬件测试表明系统能够正确显示最先抢答的选手号码,并对答题时间进行30s的限时报警以及复位重新抢答功能。实验证明该抢答器具有很强的功能扩充性,应用效果良好。

This paper designs a multipath responder system taking EDA technology as a means of development,which uses Altera Company＇s development platform Quartus Ⅱ tools to compile,simulate,and test EPM570T144C5N devices downloaded to the MAX Ⅱ series.Hardware test shows that the system can correctly display the number of contestant the earliest raced to answer,and do a 30s timed alarm of the time to answer and reset the answering function.Experiments show that the responder has very strong functional expandability and a good application effect.
