The traditional use of discrete components or general purpose digital circuit design method of electronic circuit design cycle is long, expensive, poor portability. In this paper, sine wave generator, for example, circuit design using EDA technology, focusing on the use of VHDL description to complete the direct digital synthesizer (DDS) design, DDS ROM from the phase accumulator and sine lookup table composed of two functional blocks, including ROM lookup table by the LPM-ROM modules trillion to implement.
