Thank you for your reply!

I want to ask you another question,Now I have added a control module to the MAC's avalon slave interface,I found that the out signal readdata[31..0] have nothing out,so I set the control module'sclk(5MHz) five times slower than the MAC clk(25MHz) input,the out signal readdata[31..0] have some thing out,but ,they are not what I want ? and the signal waitrequest changed several times ,then it gone to high,not to jump any more!

So ,I want to know how to exactly use the avalon slave interface?
