ID:13024 Output pins are stuck at VCC or GND

CAUSE: The output pins are minimized to either VCC or GND in a design file. This condition may be the result of the optimization process performed during logic synthesis.

ACTION: If you intend the output pins to behave in this manner, no action is required. Otherwise, check the design file for errors and ensure that the project's logic does not reduce to VCC or GND.
