Design of Arbitrary Waveform Generator Based on the FPGA
Abstract: In the paper, the arbitrary waveform generator that based on the FPGA and
DDS technology is designed, and parts of the system are discussed in detail. This design uses VHDL language to finish the design of the system each module of the hardware description by the hardware structure and the working style of refactoring.Completed the simulation of the system in Quartus II 9.0 environment and simulated the hardware test in the laboratory experiment box, simulation and hardware testing results show that the design has reached the expected effect, flexible control, good performance. And the system has a wide range of frequency, high precision of frequency, adjustable phase and amplitude, simple structure of circuit and so on, which also proves the reliability and feasibility of DDS based on the FPGA.
Key words: FPGA; DDS; Quartus II; Arbitrary Waveform Generator
