作业3 DDS模块设计
作业要求
在FPGA上设计一个DDS模块，在DE0 开发板上运行，在FPGA芯片内部合成出数字波形即可。不用输出模拟信号，本模块满足以下条件
- 使用板载晶振的50MHz时钟，合成以下频率的信号
- 1、500KHz 正弦波信号。 2、1MHz 正弦波信号。 3、3MHz 正弦波信号。
- 频率字字长32位，波表ROM尺寸为 10比特地址，1024个word
- 波形格式为2补码格式，12比特量化
- 每个CLK输出一个有效样点。
- 输入信号为频率字和频率字输入使能信号
- 使用板载的拨码开关（Switch）控制生成的波形信号的不同频率。
注意：波表ROM代码是用matlab或C打印生成的。不要手写
