ID:18631 Reconfigurable or reserved core partition '<string>' has an output '<string>' which is driven by global source '<string>,' but signals from reconfigurable or reserved core partitions may not drive the global networks, even if the original source of the signal is not in the partition. Modify your design to feed the global destinations from outside the partition, or disable global promotion for this signal.

CAUSE: All signals from a reconfigurable or reserved core partition must terminate in a wire LUT, but the specified partition includes a signal on a global network as an output. However, LUTs cannot be used inside a global network, nor can a global signal drive a LUT input in a reconfigurable or reserved core region. Only clock and asynchronous clears may be fed by global networks inside such a region. As a result, this partition is invalid.

ACTION: If the signal should not be using a global network, apply the GLOBAL_SIGNAL assignment to the signal with a value of "off," or ensure that the signal is not fed by a clock buffer primitive. If the signal must use a global network, restructure your design such that all non-reconfigurable and non-periphery reuse destinations of the signal are fed from outside the reconfigurable or periphery reuse partition.
