ID:12016 Net "<name>", which fans out to "<name>" is connecting a Partition with logic other than a single Bidirectional pin

CAUSE: In a design file, more than one value is assigned to the specified net. The net, however, is connecting a partition's output/bidirectional port with multiple logic, possibly tri-state logic. The only tri-state logic allowed to be connected to a partition is a single bidirectional pin.

ACTION: Reconstruct the design so that the partition port will not be part of a bus contention with multiple logic.
