Design and Implementation of Front-End of DDS Based on ASIC Flow

CHEN Liang,ZHANG Tao(College of Information Science and Engineering,Wuhan University of Science and Technology,Wuhan 430081,P.R.China)  
System architecture of a direct digital synthesizer(DDS) was constructed based on ASIC design flow.Module partitioning and algorithm analysis were described.Functional simulation at RTL level was performed and test-bench was written using Verilog HDL.All digital portions in the module were designed and simulated,and synthesis optimization and timing analysis were also performed.To meet the requirement of high frequency and low jitter,repeated synthesis was necessary,in which speed and area should be taken into consideration.Finally,digital modulation with DDS was functionally simulated and tested.
