Error (11924): Bank has conflicting VCCIO settings

Description

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

Resolution

As long as VIH and VIL specifications 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 has been fixed since Intel® Quartus® Prime Pro and Standard Edition Software version 18.1.
