Hi,
If I want to generate the fixed amplitude and Fixed Frequency statble Sine Wave, is NCO MegaCore Function is the right choice? Outof the following Generation Algorithm Small ROM Large ROM CORDIC and Multiplier-Based Which one gives the Most Stable Frequency Output? -- megafunction wizard: %NCO v11.0%Link Copied

the different generation algorithms are largely a resource/time trade off
if you have lots of extra RAM in your design, choose one of the ROM based NCOs if you have lots of logic leftover use a parallel CORDIC if you've got a high clock rate but low sample rate use a serial CORDIC if you've got some multipliers left over use a multiplier based a common specification for NCOs is spurious free dynamic range SFDR. you can get an idea of what you can achieve in the MegaWizard when you vary the parameters
