ID:13070 The ALT_BIDIR_DIFF or the ALT_BIDIR_BUF primitive instance <name> is not connected to the altddio_bidir megafunction
CAUSE: The specified instance of the ALT_BIDIR_DIFF or the ALT_BIDIR_BUF I/O primitive is not connected to the altddio_bidir megafunction. This is illegal. The primitive must be used with the altddio_bidir megafunction.
The ports of the primitive must be connected as follows:
ALT_BIDIR_DIFF
ALT_BIDIR_BUF
| port | Connected to |
| bidirin | the padio port of the altddio_bidir megafunction |
| oe | the oe_out port of the altddio_bidir megafunction |
| io | bidirectional pin |
| iobar | bidirectional pin |
| port | Connected to |
| bidirin | the padio port of the altddio_bidir megafunction |
| oe | the oe_out port of the altddio_bidir megafunction |
| io | bidirectional pin |
ACTION: Use the primitive with the altddio_bidir megafunction and compile the design again. If you just want to name your negative bidirectional pin, use the ALT_IOBUF_DIFF or the ALT_IOBUF primitive instead.
