De2_tv

This is a part from module Reset_Delay in DE2_TV project:

begin

if(Cont!=22'h3FFFFF)

Cont <= Cont+1;

if(Cont>=22'h1FFFFF)

oRST_0 <= 1;

if(Cont>=22'h2FFFFF)

oRST_1 <= 1;

if(Cont>=22'h3FFFFF)

oRST_2 <= 1;

endbegin

I can't understand this part, why are used these numbers?

could someone help me

Thanks

    its some kind of reset sequence, you could calculate the time between each reset by looking at the count value and clock frequency. i'm not sure why the resets have this sequence, but i would start by looking at what each reset is connected to
