You can still use a LUT for the variable frequency sin (x) function. Just generate a LUT of 1000 or so (depending on your desired resolution) entries of a single cycle of a sine wave. Then you decide how many entries to jump through each clock cycle based on the desired frequency. As an example, if your clock is 1MHz, and the desired output frequency is 1KHz, then you step to the next LUT entry every clock (complete the period in 1000 clock cycles).Apr 04, 2013 · Hai all, I need to generate a sine wave in verilog..
