hi regards to all...

i need to know whether is it possible to generate a sin wave in Quartus II software using VHDL coding. if yes pls show the ways.. thank you...[/img]
 

To generate sine wave of a fixed frequency(Fout), then you just load sine wave samples in to ROM and read them with a sampling clock(Fclk).

Fout = Fclk/Number of samples.
 

The frequency may be also variable. The technique is called numerical controlled oscillator (NCO). But the sine signal is represented digitally only. You need a DAC to get an analog signal.
