This seems like a hierarchy to me, where RXStreamChannel is one of my modules and then the following becomes more specific in the net/gate that is in the path of the timing loop? How can I identify these elements in the schematic/net-list? An explanation of the hierarchy and what's its describing would be great. Thanks!
This error is new to me, but a loop usually indicates something feeding back on itself. Can you examine the logic of your RXStreamChannel component to see if there is a combinational loop (no flip-flop)?
