modelsim的使用如何操作使用和安装如何安装

Xilinx FPGA 时序约束资料，原厂出品，经典不需要理由(Xilinx FPGA timing constraint information, original, classic no reason)

yuv444 与yuv422相互转换verilog语言(yuv444 to yuv422)

美国人写的各种类型的fpag设计指导，非常详细的介绍了从fpga的型号，结构，实现，编程，等各个方面的要点。-Written by Americans of all types of fpag design guide, very detailed introduction from the FPGA models, structure, realize, programming, and other aspects of the main points.

基于FPGA 的VGA波形显示，dds产生三角波正弦波(Vga waveform display based on FPGA, using DDS to generate sinusoidal triangular wave)

该资料为基于FPGA 的NAND flash控制器研究，语言为VHDL，代码已通过仿真验证

这是一个二进制的最简单分频器，是一个简短的fpga代码，用verilog书写(This is the most simple of a binary frequency divider, the fpga is a short code, written in verilog)

这个是DE2上的SDRAM 四个端口的驱动代码，相当实用！(This is a four-port SDRAM on a DE2 driver code, very useful!)

xlinx fpga实现fft功能，利用ip核，包含源程序及完整工程文件，直接就能使用(The fft function xlinx fpga ip-core contains the source code and complete the project file, and can be used directly)

使用ISE软件实现OFDM通信系统的框架搭建，完成上板前的仿真工作(Realization of OFDM communication system with ISE software)

说明：  包含一个ALU，实现斐波那契数列的计算。1.接受两个6位二进制输入。2.通过手动输入的时钟驱动每个周期进行一次计算。3.结果输出到led灯（使用NEXYS4开发板）(Including an ALU to realize the calculation of Fibonacci sequence. 1. Accept two 6-bit binary inputs. 2. Each cycle is driven by a clock input manually. 3. Output to LED lamp (using NEXYS4 development board))
