数字锁相环频率合成器的vhdl实现的源代码-Digital PLL Frequency Synthesizer vhdl source code to achieve

FPGA做的PLL 可以使用，比软件自带的省一些资源-PLL can be used FPGA to do more than the software comes with some of the resources of the province,

用VHDL写的数字锁相环程序源码 pll.vhd为源文文件 pllTB.vhd为testbench 可直接使用。 -Written using VHDL digital PLL pll.vhd program source code for the source text file pllTB.vhd testbench can be used directly.
