Function signal generator based on FPGA

The Function Signal Generator based on direct digital frequency synthesis is introduced in the paper.It is designed based on DSP Builder of FPGA,and can generates sine wave,sawtooth wave,square wave,triangle wave etc.Simultaneity,the Function Signal Generator's function simulation and timing simulation with ModelSim and QuartusII show that the Function Signal Generator's frequency and phase can be adjusted flexibly,at the same time,it has a high resolution and fast settling time.
