Synthesisable Sine Wave Generator This page offers you a customisable sine wave generator. Below is a generic VHDL description of a sine wave generator. It is parameterised by constants and subtypes declared in sine Generating a pure sine wave as output form FPGA using VHDL code. The Method of generating Pure Sine waves from a previously stored samples in memory & reading the memory at varying rate / memory locations to change the frequency and or the spectral purity of the sine wave is called Direct Digital Synthesis. This allows you to generate wide range of sine freq's with the required spectral purity. Useful in Mobiles & Software Defined Radio's & any other similar application. DDS ASIC's are also available but are usually expensive. FPGA's are cheaper alternative. FPGA can only generate the required Digital output , but the analog singal cant be generated without a filter or a DAC & some basic filtering. Most FPGA vendors have a free DDS IP Core with their IDE (Integrated Dev Environment). Checkout Actel/ Xilinx / Altera IP's. If you cannot manage to get an IP, you can pull a DDS function block in Matlab & utilize a 3rd party tool . DDS is sometimes also known as DDFS : Direct Digital Frequency Synthesis.
