WebApr 24, 2024 · Scenario: when FIFO write only (WR), then full = 1 and read (RD) =1 and empty=1. As observed from Fig. 4, FIFO is full or FIFO_FULL=1, which indicates the incoming data is full, so no data will be stored in the buffer until the control signal like wr_en depends on wr_clk will high. when empty is equal to 1under boundary condition WebThe fifo in our design is at the end of the circuit supplying output to another board. We use the fifo to read data with the clock supplied externally. So there is nothing more after reading out the fifo contents in our design. In our case, the empty flag goes low 5 cycles later than data starts coming into the fifo.
