ID:176268 Can't pack node "<name>" -- no packable connection between output pin (output enable) and register

CAUSE: You turned on the Fast Output Enable Register logic option for the specified node. However, there is no valid connection in which to pack an output pin (output enable port) and register. This condition can also arise if the connection between the register and output pin (output enable port) is global, because global connections cannot be absorbed by register packing.

ACTION: Remove the Fast Output Enable Register logic option assignment on the node or remove any Global Signal logic option assignments between the register and output pin (output enable port).
