<P>The following waveforms show the behavior of dcfifo megafunction for the chosen set of parameters in design "WriteDataFifo.vhd". The design "WriteDataFifo.vhd" has a depth of 512 words of 32 bits each. The fifo is in legacy synchronous mode. The data becomes available after 'rdreq' is asserted; 'rdreq' acts as a read request. </P>
