Why is there vcc text near the clock_50 flag near the left side of your schematic Under the input text)?

Is your clock net accidentally connected to vcc? If so the message makes sense, as no logic is then dependent on the input clock_50, and that one input does not drive any logic.

I would check the schematic, and if possible the generated text nextlist, of your design. I suspect that clock_50 is not really connected.
