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.
