本代码介绍了使用VHDL开发FPGA的一般流程，最终采用了一种基于FPGA的数字频率的实现方法。该设计采用硬件描述语言VHDL，在软件开发平台ISE上完成，可以在较高速时钟频率（100MHz）下正常工作。该设计的频率计能准确的测量频率在1Hz到100MHz之间的信号。使用ModelSim仿真软件对VHDL程序做了仿真，并完成了综合布局布线，最终下载到芯片Spartan-II上取得良好测试效果。-the code on the FPGA using VHDL development of the general process, finally adopted a FPGA-based digital frequency method. The design using VHDL hardware descr iption language, the software development platform ISE completed, the higher speed clock frequency (100MHz) under normal work. The design of the frequency meter can be accurately measured in a frequency of 100MHz between Hz signal. Use ModelSim VHDL simulation software to do the simulation process, and completed a comprehensive layout cabling, downloaded to the final chip Spartan-II made good on the test results.
