CAUSE: | You used the Floorplan Editor to assign the specified output or bidirectional pin to an I/O bank with LVDS receiver or LVDS transmitter channels. However, when you use the altlvds_rx or altlvds_tx megafunctions in your design, you cannot place output or bidirectional pins on a LVDS receiver or LVDS transmitter channel location. |
ACTION: | Assign the output or bidirectional pin to an I/O bank that does not have LVDS transmitter or receiver channels. |
