| CAUSE: | You assigned both a GTL+ I/O standard, which is an open-drain I/O standard, and a 1.8-V I/O standard to pins in the same I/O bank. You cannot assign the GTL+ I/O standard and the 1.8-V I/O standard in the same I/O bank because these standards require different VREF voltages. |
| ACTION: | Assign these different voltage I/O standards to separate I/O banks. |
