What is the Clockmargin?

Hi all,

I am a new Quartus and DSP Bulder User. And I want to ask a simple question.

When using DSP Builder Advaned Blokst , we shold set 'Clock Margin(MHz)' that is in a 'Signals' Block.

But, I don't know what it is. Please tell me the meaning of the 'Clock Margin(MHz)'.

Thank you for reading my funny English !

    clock margin to account for jitter around your entered clock frequency.

    It can also be used to fool the tool for higher clock speed and so increase timing margin.
