很好的quartus软件仿真教程，flash版。

Synthesizable model of Atmel ATmega103 microcontroller. (VHDL IP)-Synthesizable model of Atmel Application of ATmega103 mi crocontroller. (VHDL IP)

如果不考虑占空比，直接利用计数器来进行分频，则占空比会发生变化。下面程序实现1：1的三分频。-if not duty cycle directly counter to the use of sub-frequency, duty cycle will change. Below a program : a third of the frequency.

HDL example source code 2/5 dff_en

用verilog写的4*4小键盘按键检测程序。本工程已经编译好。可以直接在Atera DE1 Fpga开发板上运行-Written using Verilog 4* 4 keypad keys detection procedures. The project has been compiled. Directly in the development of Atera DE1 Fpga board run

本源码是用Verilog编写的12位移位相加乘法器的设计源码，开发软件为MAX+PLUS，已经测试通过。(The Verilog source code is written in the sum of 12-bit shift multiplier design source code, developing software for the MAX+ PLUS, has been tested.)

Fonts for LCD 162x64 (6x8)

FPGA流水线设计的资料，可以作为学习FPGA开发并行操作的一个经典教材，具有很好的指导作用。(FPGA pipeline design information can be developed as a learning FPGA parallel operation of a classic textbook, has a good guide.)

说明：  verilog编写的RS485读写驱动程序(RS485 read-write driver written by Verilog)

CPLD下载线制作，内含电路图等，希望对大家有帮助-CPLD download line production, including circuit diagrams, etc., in the hope that we have to help

介绍了设计和功能实现的 16 点 FFT 流水线。 架构基于利用该算法的变化规律，设计了蝴蝶操作和乘法器模块。 基数 4 算法。该体系结构采用四种蝴蝶，和管道阶段优化的处理速度和地区之间取得平衡。
