ID:13068 The "oe" port of the I/O primitive <name> is not connected properly

CAUSE: The oe port of the specified I/O primitive is not properly connected. To use it with megafunctions, it should be directly connected to the oe_out port of the appropriate megafunction. For example, the oe port of an ALT_OUTBUF_TRI or an ALT_OUTBUF_TRI_DIFF should be connected to the oe_out port of an instance of the altddio_out megafunction. In this case, this error can also occur if you used the ALT_OUTBUF or the ALT_OUTBUF_DIFF primitive instead. Similarly, the oe port of an ALT_BIDIR_DIFF or an ALT_BIDIR_BUF should be connected to the oe_out port of an instance of the altddio_bidir megafunction.

ACTION: Connect the oe port of the I/O primitive properly and compile the design again.
