这是led流水灯的vhdl描述，很好的啊

由VHDL 语言实现的数控分频 利用的是QUARTUES环境已经得到验证-By the NC VHDL language is the use of sub-frequency QUARTUES environment has been tested

verilog例子资源，对于初学者很有帮助。-verilog examples of resources are very useful for beginners.

利用两个加法器和两个乘法器一起并行处理来实现

对于学习FPGA的同学来说仿真是必不可少的流程 但是仿真的方法signal tap是必须掌握的(For students learning FPGA simulation is an essential process but the simulation method tap signal is a must)

用FPGA产生正弦波、方波、三角波和锯齿波，可以通过按键控制输出波形及其频率，并且可以通过lcd显示输出的波形名字及频率

LIBRARY IEEE; USE IEEE.STD_LOGIC_1164.ALL; USE IEEE.STD_LOGIC_UNSIGNED.ALL; ENTITY ladder IS PORT(clk,reset:IN STD_LOGIC;

说明：  用FPGA实现8点fft，整个代码使用verilog编写，主要运用了加法器和乘法器，简单易懂(8-point FFT with FPGA, The whole code is written by Verilog, mainly using adder and multiplier, which is easy to understand)
