开发系统上采用的时钟信号的频率是20MHz，可分别设计计数器对其计数，包括计秒、分、小时、日、周、月以及年等。在每一级上显示输出，这样就构成了一个电子日历和时钟的模型。为了可以随意调整计数值，还应包含设定计数初值的电路-Development system using the clock signal frequency is 20MHz, the design can be counter to its count, including seconds, minutes, hours, days, weeks, months and years. At every level to show the output, thus constitutes an electronic calendar and clock models. Can also adjust the order value, should also be included in setting the initial count circuit

4个7段lcd同时显示的程序，已经在digilent的nexy2板上通过验证，非常好用易懂，适合初学者学习-display 4 leds

使用Verilog语言编程，在Quartus ii 上实现的误码检测装置，并通过单片机将误码结果显示在LCD上。本代码具有一定的工程实践价值。(Using the Verilog language programming, implemented on the Quartus ii error detection device, and the result of errors by the microcontroller on the LCD display. The code has some value engineering practice.)

this project is about FIR FIlter By VHdl codes in the ISE.

DDS_AD9854_for FPGA ,FPGA开发下的verilog源代码，信号发生器(DDS_AD9854_for FPGA, verilog source code, signal generator.)

本程序利用VHDL实现二维离散余弦变换，经本人测试，在Quartus II7.0软件上可正确仿真，希望大家积极采纳
