The following waveforms show the behavior of dcfifo_mixed_widths megafunction for the chosen set of parameters in design "FB_FIFO.vhd". The design "FB_FIFO.vhd" has a write-side depth of 16 words of 20 bits each. a read-side width of 10. The fifo is in legacy synchronous mode. The data becomes available after 'rdreq' is asserted; 'rdreq' acts as a read request.
The above waveform shows the behavior of the design under normal read and write conditions .
