用VHDL的玛摩尼的ASIC设计

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. 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 o

一个精确的到0.01s的时钟源程序，对于初学VHDL理解很有帮助，只给了源程序没有给出仿真波形-An accurate clock source to the 0.01s for the beginner to understand VHDL helpful not only to the simulation waveform of the source

基于Verilog的八层电梯设计，能够实现自动化的电梯控制。-Verilog based on the eight-lift designed to automate the elevator control.

vga，显示彩条，及其简单易懂，适合初学(vga, display color bars, and its easy-to-understand, suitable for beginners)

一个时钟程序，还有跑表，感觉相当不错的，有需要就下载吧-A clock procedures, as well as stopwatch, I feel pretty good, there is a need to download it

利用FPGA内核产生SPWM波，并且频率可调(The FPGA kernel is used to generate SPWM waves, and the frequency is adjustable)

读取IGS数据中心提供的sinex文件 并恢复法方程(Read sinex file IGS data centers and to restore normal equation)

PLL是数字锁相环设计源程序, 其中, Fi是输入频率(接收数据), 数字锁相技术在通信领域应用非常广泛，本例用VHDL描述了一个锁相环作为参考，源码已经调试过。编译器synplicty.Fo(Q5)是本地输出频率. 目的是从输入数据中提取时钟信号(Q5), 其频率与数据速率一致, 时钟上升沿锁定在数据的上升和下降沿上；顶层文件是PLL.GDF-digital phase-locked loop PLL design source, in which Fi is the input frequency (receive data), the digital technology in the field of communications is widely used, the cases described in VHDL as a PLL reference source has been tuned. Compiler synplicty.Fo (Q5) is the local output frequency. Objective is to extract data input clock signal (Q5), its frequency and data rate line, the clock rising edge of the data locked up and the descending; Top-level document is PLL.GDF
