1、开放性实验报告专业：电子信息工程班级：*电信*班姓名：学号：指导老师：实验一：流水灯一．实验内容利用QUARTUSII软件，构建NIOSII软核系统，编写程序，实现实验箱上LED灯的流水功能。二．实验原理通过提前设定NIOSII软核处理器的相关寄存器，控制led的IO口的高低电平输出及响应间隔时间，从而改变LED的亮灭并达到流水灯效果。三．实验步骤1.硬件设计(1).构建NIOSII软核NIOSII软核处理器包括cpu,sdram控制器，串行flash控制器，jtag_uart,sysid,pio端口。(1).PLL模块的构建实验箱的板载有源晶振频率为50MHZ,NIOSII及SDRAM

2、需要100MHZ的时钟源，因此需要用PLL模块进行倍频。PLL模块的配置如图所示：输入时钟频率为50MHZ输出时钟c0为输入时钟的2倍频输出时钟c1为输入时钟的2倍频，相位偏移-75度，为SDRAM提供工作时钟PLL模块：(1).系统连线及引脚分配qsf文件中的引脚分配：set_location_assignmentPIN_AF21-tosdram_addr[0]set_location_assignmentPIN_AE20-tosdram_addr[1]set_location_assignmentPIN_AF20-tosdram_addr[2]set_location_assignm
