FPGA 综合实验
一．摘要：
  利用Matlab产生一个周期的非负正弦波，然后对其采样，取1024 点8 位数据。在QuartusII中利用MegaWizard 生成一个1024*8bits 的存储器（ram/rom），并利用上述正弦波数据来初始化此存储器。编写VHDL 程序，按一定的方式（如顺序）将存储器中的数据读出并输出到DA 端口，编译，仿真。最后为工程添加一个signaltap II 文件，设置参数，编译，无错后下载到目标板，并在signaltap II 中观看输出到DA 端口的数据及波形。
二．实验内容：
1.利用matalb 产生正弦波数据
    matlab中命令：
    x = 0 : 2 * pi / 1024 : 2 * pi;
    y = 128 * (1 + sin(x));
    sin_table = uint8(y);
2. 创建Quartus II 工程并添加一个存储器初化文件
mystorage_inst : mystorage PORT MAP (
address => address_sig,
clock => clock_sig,
data => data_sig,
wren => wren_sig,
q => q_sig
);
3. 利用MegaWizard 产生存储器
