这时一个数字钟的VHDL程序，有计时、校时、整点报时功能，很适合做EDA设计之用...

用于串行到并行数据转换器的VHDL代码；当输入数据是串行的时，该代码是用于许多应用程序的位到字节转换的VHDL代码形成代码使用基于FPGA的LUT和D-RAM来存储数据，然后用时钟推送字节对齐的数据。

说明：  CC217编程序，verilog实现，串行输入串行输出(CC 217 program, to achieve Verilog, serial input serial output)

说明：  VHDL语言写的SRAM控制程序，在开发板上验证过。(Written in VHDL SRAM control procedures, the development board verified.)

程序设置了fpga 的 5x5点阵驱动程序，代码相对比较简洁，这个程序可以作为fpga输出控制，驱动稳压芯片工作，进而点灯

采用骏龙科技这个13.1新版本破解器.对于已经用了老版本破解器的网友，请把bin和bin64下的sys_cpt.dll删除，然后把sys_cpt.dll.bak名字改成sys_cpt.dll，也就是先恢复正版，然后用这个破解器破解。注意老的license文件也要删除，改用这个新版本破解器附带的license(Cytech Technology 13.1 using the new version of this cracker. Has been used for the old version cracker users, please sys_cpt.dll bin and bin64 under Delete, and then changed the name of the sys_cpt.dll.bak sys_cpt.dll, which is first restore genuine, then use this cracker to crack. Note that the old license file should be deleted in favor of this new version of the license that came with crack)

Testbench 不仅要产生激励也就是输入，还要验证响应也就是输出。当然也可以只产生 激励，然后通过波形窗口通过人工的方法去验证波形，这种方法只能适用于小规模的设计(The Testbench not only to generate incentives to input, verify that the response is output. Of course, can only produce Incentive, and then the waveform by the waveform window by artificial means to verify, this method is only applicable to small-scale design)

用CPLD驱动扬声器实现音乐的播放，程序是用VERILOG写的，-CPLD driver speakers with music player, the program is written in VERILOG,

9针的rs232与fpga之间的串口通信源程序(Rs232 9 pin serial communication with the source between fpga)

本文件是可以直接使用下载到FPGA里面使用，里面包含时钟分频电路，串并转换和并串转换电路，多通道信号加权的乘加电路等。-The document may download to FPGA chip to complete the clock divider,serial-to-parallel,parallel-to-serial,and multiple-add circuit for multiple channels weight calculation

数控分频器的设计 数控分频器的功能就是当在输入端给定不同输入数据时，将对输入的时钟信号有不同的分频比，例3的数控分频器就是用计数值可并行预置的加法计数器设计完成的，方法是将计数溢出位与预置数加载输入信号相接即可。(NC NC divider divider design of its function is when the input given different input data, input the clock signal will have different frequency than, for example 3 is to use the NC prescaler count preset value of the adder parallel counter design is completed, the method is to count the number of overflow bit with preset load to the input signal phase.)
