这是个的VHDL点亮LED的程序，大家一齐分享吧

应用背景关键技术本书采用“做中学”介绍VHDL和FPGA技术的概念和设计人员通过一系列的实验方法。

ecc椭圆算法RTL,verilog源代码经过验证，用于FPGA或者ASIC(ECC elliptic curve encryption algorithm for Verilog implementation)

EDA设计实验，用VHDL编写的数字时钟代码，能显示分，秒，小时。根据所设置的频率不同，能够调整时间快慢。-EDA design of experiments, prepared by VHDL code digital clock showing the hours, seconds, hours. According to the frequency of different settings, time to adjust speed.

本例程位于 VMD642_CPLD目录中。 使用 CPLD 实现辅助译码、LED 指示灯控制、看门狗等各种逻辑控制电路。源程序使 用 Verilog HDL书写，编译开发系统使用 Cypress公司的 Warp 6.3。(This routine is located VMD642_CPLD directory. Using CPLD implementation auxiliary decoding, LED indicator control, watchdog, and other logic control circuitry. Written using Verilog HDL source code, the compiler development system using Cypress' s Warp 6.3.)

6713emiftofpgatopci,这个是完整的一套从6713的emif到fpga的双口ram，然后主机通过9054到双口ram，交换数据完成-6713emiftofpgatopci, this is a complete set of the EMIF from 6713 to the FPGA

说明：  FPGA串口实现。 发送和接受数据功能代码(FPGA serial interface. Send and receive data function code)

VHDL语言100例详解，北京理工大学ASIC研究生出版，这里是51~94个examples-VHDL language of 100 cases explain, Beijing Institute of Technology, Graduate ASIC publication, here is the 51 ~ 94 examples

这是这本书的第四个版本，现在这个版本不仅提供了VHDL语言的覆盖面，但设计方法的信息，以及。此版本将指导读者通过创建一个VHDL设计的过程中，模拟设计，综合设计，放置和布线设计，使用的重要模拟验证的最终结果，新的技术，称为全速调试，提供了极其快速设计验证。在这个版本的设计，例如已被更新(This is the fourth version of the book and this version now not only provides VHDL language coverage but design methodology information as well. This version will guide the reader through the process of creating a VHDL design, simulating the design, synthesizing the design, placing and routing the design, using VITAL simulation to verify the final result, and a new technique called At-Speed debugging that provides extremely fast design verification. The design example in this version has been updated to reflect.)

由verilog编写的乘法器，通过两个文件的调用实现。由于子模块的调用使得程序简化了许多。(Prepared by the Verilog multiplier, through the realization of the two documents call. As the sub-modules to simplify the procedure call makes a lot.)

说明：  一个PN序列发生器，大M序列，供参考学习，(A PN sequence generator, the M series, for reference study,)
