上一节中我们搭建了DDS的每一个实现细节,本设计将直接采用高层次封装的block实现NCO功能。添加block按下图连接: data_tready接口赋1,永远保持有效。使用Scope观察DDS Compiler输出的正弦波和余弦波。此外还有一个输出有效信号data_tvalid,在设计中不需要,为其连接一个Terminator,这样在运行时不会因为管脚没有连接而报错...
System Generator的实现 A. 2FSK信号的产生在System Generator中实现非常简单,双击运行System Generator(按自己的版本打开即可),然后就会调用MATLAB的运行程序,等待打开完成; 单击MATLAB工具栏的Simulink按钮,打开Simulink,如下图所示: 图 4 运行Simulink B. 打开Simulink后,新建一个空白模型,打开Library Browser,将仿真库...

DDS SYSTEM WAVEFORM GENERATORPROBLEM TO BE SOLVED: To improve convenience of a DDS system waveform generator by providing an additional circuit so as to provide a pulse generating function excellent in stability and precision of a period and a pulse width. ;SOLUTION: When a trigger signal is ...
5. PicoBlaze compiler script fails when using long module names. 6. The DDS fails to generate if Phase Dithering is selected and the Phase Angle is greater than the Phase Accumulator. 7. MAP reports errors when XST is used to synthesize a design containing the DDS core. Please see . ...

The non-object-oriented way to do this would be to write a single function which looked at the type of its argument and behaved accordingly. So, to find the area of an object x we would do: (defun area (x) (cond ((rectangle-p x) (* (height x) (width x))) ...
I'm currently running Vivado 2019.1 with matlab 2019a using system generator. I have run into a situation several times now where certain combinations of precision between blocks will result in a sysgen simulation hanging at the "initializing" step,which is the last step of preparation before a...
