As the third generation frequency synthesizer,Direct Digital Synthesizer(DDS) has been widely used due to its many significant advantages.An optimized DDS based on digital ASIC design flow is designed and implemented by using the pipeline technology and the symmetry character of a few functions.The design steps from the structure divide to the auto placement and route are given out in detail,and each involves in the design purpose,software in use and design points.Theoretical results show that the proposed DDS has advantages of small size and can run at 150 MHz clock frequency,which meets requirement of the design.
