标题: helllo [打印本页] 作者: chindji 时间: 2010-8-25 06:36 标题: helllo The following is excerpted from Reset_Delay.v of the project de2-d5m
always@(posedge iCLK or negedge iRST)
begin
if(!iRST)
begin
Cont <= 0;
oRST_0 <= 0;
oRST_1 <= 0;
oRST_2 <= 0;
end
else
begin
if(Cont!=32'h13FFFFF) Cont <= Cont+1;
if(Cont>=32'h1FFFFF) oRST_0 <= 1;
if(Cont>=32'h2FFFFF) oRST_1 <= 1;
if(Cont>=32'h13FFFFF) oRST_2 <= 1;
end
end
I don't understand why it sets cont as 32'h1FFFFF，32'h2FFFFF，2'h13FFFFF.
Can anybody help me?
