Webin TB_FWFT_FIFO: component declaration: D0 : in STD_LOGIC_VECTOR (15 downto 0); So in one case you have DATA_WIDTH - 15 downto 0, which evaluates to 1 downto 0. In the other case you have 15 downto 0. I expect in FWFT_FIFO you intended to write: D0 : in STD_LOGIC_VECTOR (DATA_WIDTH - 1 downto 0); WebThe following waveform shows what reading from a FWFT FIFO can look like: Note that the first valid value at @dout appears while @rd_en is low, and that @empty changes to low at the same time as the valid value appears. As just mentioned, @empty means "@dout not valid" on an FWFT FIFO, and the waveform reflects that.
