The following waveforms show the behavior of dcfifo_mixed_widths megafunction for the chosen set of parameters in design "fifo8to16_2k.vhd". The design "fifo8to16_2k.vhd" has a write-side depth of 2048 words of 8 bits each. a read-side width of 16. 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 .
