ID:13008 TRI or OPNDRN buffers permanently disabled
CAUSE: You connected the output enable input signal of a
TRI
or
OPNDRN
buffer to
GND
. The tri-state buffer does not reduce to a simpler form. This condition may be the result of logic synthesis. If you connected the TRI
or OPNDRN
buffer connected to a bidirectional pin, the message indicates that the pin will always drive in.
ACTION: Check the design file for errors. Connect the input to a node other than GND
if you want to enable the output enable input. You might also want to substitute an
INPUT
pin for the
BIDIR
pin (and remove the TRI
or OPNDRN
buffer) if the pin is always driving in.
