适用于FPGA初学者,一个流水灯的程序,用VERILOG语言写的.

SPI控制器，基于VERILOG描述，分模块设计，共6个模块，时钟产生模块，移位模块，主模块，从模块，定义模块，顶层模块。(SPI controller, based on the VERILOG description, sub-module design, a total of six modules, clock generation module, shift module, main module, from the modules, custom module, top module.)

说明：  杜晓斌和陈兴文-FPGA和单片机串行通信接口的实现一文提出了FPGA与单片机实现数据串行通信的解决方案。在通信过程中完全遵守RS232 协议，给出了发送模块的vhdl源代码。 (杜晓斌and陈兴文-FPGA single-chip serial communication interface and the realization of a text proposed by the FPGA and MCU serial data communications solutions. In the communication process in full compliance with the RS232 protocol is given to send the VHDL source code modules.)

这个是vhdl中很常见的jk filpflop的文件只用于很小数位的变化 其中的jk文件是up down运算都符合的(This is a very common vhdl jk filpflop file is only used for very small changes in a digital file which jk is up down operations are met)

这段代码是用VHDL解释椭圆曲线密码术的。这段代码包含了使用FPGA板进行ECC加密的必要算法！ ；

可以产生正弦波，三角波、锯齿波、方波，要求频率1Hz-100kHz，步进1Hz，具有自动扫频功能； 正弦波的相位可调，方波的占空比可调； (Can generate sine wave, triangle wave, sawtooth wave and square wave, the required frequency of 1 hz- 100 KHZ, step 1 hz, with functions of automatic frequency sweep The phase adjustable sine wave, square wave duty ratio is adjustable )

说明：  HDB3编码通过verilog实现，通过modelsim仿真(HDB3 coding is implemented by Verilog and simulated by Modelsim)

自己在ISE下用VHDL写的UART，简单，易懂(in ISE using VHDL was the UART, simple, understandable)
