thanx kaz,yes scfifo is that u understood.

my problem was in the simulation in quartus but the problem was the manipulation of the wrreq and rdreq for the rising clock edge of the clock,that is, the clock must see the wrreq or rdreq' values @ its positive clock edge as u mentioned,if not, u may not see the ordinary operation.

So,now i m ok with the scfifo's usage.
