摘　　要：基于FPGA器件EP1K30QC208芯片,采用VHDL设计实现了一个相位、频率均可控制的数字频率合成器,并在ZY11EDA13BE试验系统中完成硬件测试。经实验验证,输出波形达到了技术要求,性能良好,控制方便,证明了基于FPGA的DDS设计的可靠性和可行性。Based on FPGA of EP1K30QC208 chip,Digital frequency synthesizer whose phase and frequency can be controlled has been designed with VHDL and its hardware has been tested in ZY11EDA13BE system.The results of the experiments show the output waveform has met the technical standards and that its operation is in good state.It also illustrates this method is effective and easy to use.
