实现dds功能，利用quartus软件， 子模块包括加法器，锁相环，date-rom 利用原图将各模块综合，利用ps2键盘控制频率及相位。-Dds realize functions, using Quartus software, sub-modules including the adder, phase-locked loop, date-rom image to the module using integrated, using ps2 keyboard to control the frequency and phase.

说明：  介绍USB PHY接口中的UTMI接口， 对使用Verilog进行USB接口编程具有帮助。(This paper introduces UTMI interface in USB PHY interface. It is helpful for programming USB interface with Verilog.)

quartus ii 环境下，一个完整的利用TEXTIO仿真的源代码，包括读数据文件和输出数据到文件。(Under quartus ii environment, a complete simulation using TEXTIO source code, including reading data files and output data to a file.)

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
