WebWhen I simulate the design, you can see how data is read in the same order in which it was placed into the FIFO. Additionally, the w_full line goes high when the FIFO is full (all the memory elements are filled with data) and the r_empty line goes high when the FIFO is empty (no data left to read). The internal circuitry prevents reading when ...
