Design of Multipath Waveform Generator Based on FPGA

In order to design a programmable multipath waveform generator, VHDL is used to design every module. It is consisted with the waveform input, FPGA module, digital-to-analog conversion (D/A) module, display circuit. By pressing the keys, eight waves can be chosen and shown in the oscilloscope. With the characteristics of low cost, portable and expandable, it can be widely used in electronic circuit system.
