WebMar 15, 2024 · Also, FIFO 2b needs to account for that delay. If the rates are not matching, there will be deadlocks. Make sure to have a meaningful testbench and to cosimulate your design. (The FIFO's depth can be changed with the pragma #pragma HLS STREAM variable=fifo_1 depth=N). Final Thoughs WebFor a stall-free cluster, the exit node of the cluster has a FIFO with a depth greater than or equal to the latency of the cluster. This FIFO stores any in-flight data that needs to be passed outside of the cluster. To see the size of the cluster exit FIFO, click the exit node and see the information in the Details pane.
