【摘要】 为了配合我校EDA技术的教学和实验,以Altera公司的CPLD器件EP1K50QC208-3为核心,外接显示电路、键盘、模数转换、输入开关、通信接口、电源和时钟源等,开发了CPLD实验系统。介绍了详细的硬件设计电路,以及自主开发的CPLDDN下载软件。本实验系统从设计完成至今,已经过三届师生使用,不仅用于学生的实验、课程设计和毕业设计中,而且也为科研人员提供了便利。实际使用效果表明,本实验系统很好地满足了教学和实验的需要。更多还原

【Abstract】 In order to cooperate with EDA technology’s teaching and experiment,we developed the CPLD experiment system using the Altera company’s CPLD device EP1K50QC208- 3 as the core device,including display circuit,keyboard circuit,analogue to digit convert circuit,input switch circuit,communication interface circuit and power supply,etc. This paper gives the detailed hardware circuit design,and introduces the independent development of CPLDDN download software. Since the system is completed,it had been used by three sessions of teachers and students. It is not only used by students’ experiment,curriculum and graduation design,but also provides convenience for researchers.Actual use effect shows that this experimental system well meets the need of teaching and experiment.更多还原
