Due to a problem in Intel® Quartus® Prime software version 18.0 and earlier, you will see this error in Intel Arria® 10 devices in the cases where :
- 2.5V Input standard is placed in a 3VIO bank with 3.0V I/O standard of which VCCIO is 3.0V
- 3.0V Input standard is placed in a 3VIO bank with 2.5V I/O standard of which VCCIO is 2.5V
As long as VIH and VIL specification are satisfied, you can use the following input standard as a workaround:
- 3.0V input standard instead of 2.5V input standard
- 2.5V input standard instead of 3.0V input standard
Refer to Intel Arria 10 Device Datasheet for VIH and VIL specifications of 3.0V and 2.5V input standards.
This problem will be fixed in future version of Intel Quartus Prime software.
