The following waveforms show the behavior of dcfifo_mixed_widths megafunction for the chosen set of parameters in design "fifo_16to8_2k.vhd". The design "fifo_16to8_2k.vhd" has a write-side depth of 1024 words of 16 bits each. a read-side width of 8. The fifo is in show-ahead synchronous mode. The data becomes available before 'rdreq' is asserted; 'rdreq' acts as a read acknowledge.
The above waveform shows the behavior of the design under normal read and write conditions .
