Detailed Documentation
This system implements a MATLAB model that utilizes DSP Builder to generate both VHDL source code and testbench files for a Direct Digital Synthesizer (DDS) implementation. The generated VHDL code includes the core DDS algorithm implementation featuring phase accumulation and sine/cosine waveform generation components. The accompanying testbench provides comprehensive verification stimuli covering various frequency configurations and phase settings. The complete design has been validated through functional simulation in ModelSim, confirming proper waveform generation and timing characteristics. The implementation demonstrates automated workflow integration between MATLAB/Simulink environment and HDL simulation tools for digital signal processing applications.
