I2C的VHDL源码，从机模式，编译通过。

直接数字频率合成，可以直接输出所需要的波形-Direct digital synthesizer, you can direct output of the waveform required

verilog代码实现的数字密码锁。通过4个并行的10位移位寄存器，分别记录在时钟上升沿时A,B,C,D的输入情况，比如某上升沿输入A，相应时刻A对应的移位寄存器输入1，其他三个移位寄存器输入都为0.另外4个并行的10位寄存器记录密码。这样，密码锁不仅可以识别字符数量，还可以判断出字符的输入次序。(verilog code of digital lock. By four parallel 10-bit shift register, respectively, recorded in the clock rising edge A, B, C, D of inputs, such as a rising edge of input A, the corresponding moments A 1 corresponding to the input shift register, the other three shift bit register inputs are 0. another four parallel 10-bit registers record the password. This lock can not only identify the number of characters, you can also determine the character of the input sequence.)

用 vhdl 语言实现，上下计数器使用边缘触发一个 4 位纹波计数器。积极的边沿触发。 包含的所有文件。试验台架波形。针对采用赛灵思文件

本CD-ROM包括《Verilog-HDL实践与应用系统设计》一书中的全部例子，这些例子全部通过了验证。第七章以后的设计实例，不仅有Verilog-HDL的例子，也附了包括VB、VC++等源程序,甚至将DLL的生成方法也详尽地作了说明。 -the CD-ROM include "Verilog-HDL Practice and Application System Design," a book the whole Examples of these examples were passed certification. After the seventh chapter, a design example is not only Verilog-HDL example, the report include VB, VC and other source files, even DLL generator also described in detail.

vhdl 计数器源程序，大家看看吧 vhdl 计数器源程序，大家看看吧-vhdl counter source, we see it vhdl counter source, we see it

BCD码减法实现程序，非常完整，采用Verilog HDL语言实现。(BCD subtraction to achieve program code, very complete, using Verilog HDL language.)

说明：  用FPGA进行等精度频率和相位差测量的程序，本程序是在EPEC6Q240C8下的程序(Carried out with the FPGA such as the frequency and phase measurement precision of the procedure, this procedure was the procedure under the EPEC6Q240C8)

用VHDL实现串口 可以实现与pc机的通信 收发 中断都可以 效果比较好-VHDL implement serial port, it can communicate with pc, it can accept and send message, and it can be interrupted.
