ID:16720 Propagated pin attribute from lower-level pin "<name>" to top-level pin "<name>". Did not propagate pin attribute to the other top-level pins listed below

CAUSE: You compiled the current design. During the compilation, the Quartus Prime software propagated a pin attribute from the specified lower-level pin to a top-level pin. However, the lower-level pin is connected to more than one top-level pin and the Quartus Prime software can propagate the pin attribute to only one top-level pin; therefore, the Quartus Prime software propagated the pin attribute only to the specified top-level pin, and not to the other top-level pins. The messages that follow this message in the Messages window and in the Analysis & Synthesis Messages section of the Report window list the top-level pins to which the Quartus Prime software did not propagate the attribute.

ACTION: If you want the pin attribute in a different top-level pin, make the pin attribute explicitly to the top-level pin and do not rely on the Quartus Prime software to automatically propagate the pin attribute. If the lower-level pin should connect to only one top-level pin, correct the multiple connections in the design. Otherwise, no action is required.
