ID:275032 Can't connect "<name>" to "<name>" directly -- both signals are output signals

CAUSE: In a Graphic Design File (.gdf), you connected an input pin to another input pin or an output symbol port. However, the connection is illegal because the connected input pin acts as an output signal in its connected network. You cannot connect output signals to other output signals.

ACTION: Replace the connected input pin with an output or bidir pin, or reconnect the input pin or the output symbol port to a legal signal.
