通用：我新的FFT VHDL VHDL，我试图用Xilinx的FFT核，但当…
FFT vhdl generic: I m new to vhdl, and I tried to use xilinx fft core, but when I try to simulate it in test bench using ise simulator, I get zero results.
here is what I do:
1- from core generator I choose fft core and create .vhd & .vho & .xco files.
2- I add the .xco & .vhd files to my project.
3- I create a new vhdl source as a wrapper to the core and add the code from the .vho files where it exactly says, and take the ports of the component and add it to the entity of the wrapper file.-FFT vhdl generic: I m new to vhdl, and I tried to use xilinx fft core, but when I try to simulate it in test bench using ise simulator, I get zero results.

PWM
说明： 通过一个计数器来实现输出信号的占空比要求，可以将duty_cycle分配到拨码开关上,LED分配到发光二极管上,然后调节拨码开关,即可看到LED的亮度发生变化.(The duty cycle of the output signal can be assigned to the dial switch by a counter, and the LED can be assigned to the light emitting diode. Then the brightness of the LED can be seen by adjusting the dial switch.)

dds_test
直接数字式频率合成器DDS设计、Verilog。
产生的信号可以是正弦波或方波、三角波、锯齿波等，自选。
采用DDS技术，将所需生成的波形写入ROM中，按照相位累加原理合成任意波形。
此方案得到的波形稳定，精度高，产生波形频率范围大，容易产生高频。
本实验在设计的模块中，包含以下功能：
（1）通过 freq 信号输入需要的频率的值；
（2）通过 wave_sel 信号选择所需的波形；
（3）通过 amp_adj 信号选择波形放大的倍数。(DDS design of direct digital frequency synthesizer, Verilog.
The generated signal can be sinusoidal or square wave, triangular wave, sawtooth wave and so on, optional.
By using DDS technology, the required waveforms are written into ROM, and arbitrary waveforms are synthesized according to the principle of phase accumulation.
The waveform obtained by this scheme is stable, accurate and easy to generate high frequency waveform.
This experiment includes the following functions in the designed module:
(1) Input the required frequency value through freq signal;
(2) Choosing the required waveform by wave_sel signal;
(3) Select the multiplier of waveform amplification by amp_adj signal.)
