读取IGS数据中心提供的sinex文件 并恢复法方程(Read sinex file IGS data centers and to restore normal equation)

60进制计数器,（由一六进制和十进制连线组成）(60 binary counter (hexadecimal and decimal by a connection form))

基于FPGA的频率测量，能测量方波信号的频率、占空比、相位差。范围100mHz~200MHz，精度0.0001Hz(The frequency measurement based on FPGA can measure the frequency, duty cycle and phase difference of the square wave signal. Range 100mHz~200MHz, precision 0.0001Hz)

收集的QuartusII的使用手册，包含了几个pdf文件，比较不错的参考手册-Collected QuartusII s manual contains a number of pdf files, compare a good reference manual

测量周期,此程序已经在EP2C板子上成功实现(mesure cycle)

VHDL实例,有近百个实例,都是可以在quarturs 上进行仿真的,大部分都可以通过,对初学者是一非常不错的-VHDL example, there are nearly a hundred examples, can be carried out in quarturs simulation, most of them can pass, for beginners is a very good

基于quartus 的一些程序 都是verilog 还是比较有用的 -Based on some of the procedures Quartus Verilog are still quite useful

说明：  使用Verilog，以Quartus II 为平台，编写了一个DDS信号发生器程序。(Using Verilog and Quartus II as the platform, realizing the DDS signal generator program .)

Verilog 下脉冲发生器的源代码，可用于模拟三相交流电过零点，主要用于调试一些类似SVC（无功补偿）控制器的一些算法-Pulse generator under the Verilog source code, can be used to simulate three-phase alternating current zero-crossing point, mainly for debugging similar SVC (reactive power compensation) controller of a number of algorithms

三体模型仿真计算样例，基于特定的java浏览器插件对象，以非常形象的方式展示了三体运动物体的规律，可以调节运动参数，实时查看运动变化情况。
