ID:14829 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_BUF
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
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.
