6.5.1. Avalon® Streaming Splitter Intel® FPGA IP Backpressure
When the Qualify Valid Out option is enabled, the out_valid signals on all other output interfaces are gated when backpressure is applied from one output interface. In this case, when any output interface deasserts its ready signal, the out_valid signals on the other output interfaces are also deasserted.
When the Qualify Valid Out option is disabled, the output interfaces have a non-gated out_valid signal when backpressure is applied. In this case, when an output interface deasserts its ready signal, the out_valid signals on the other output interfaces are not affected.
Because the logic is combinational, the Intel® FPGA IP introduces no latency.
