Altera PHYLite for Parallel Interfaces IP Core GUI Shows Unsupported Input OCT Values

Description

Input OCT Values for the following I/O standard are not supported in Arria 10 devices.

• SSTL-125: 20 Ohm with calibration
• SSTL-135: 20 Ohm with calibration
• SSTL-15: 20 Ohm with calibration

If you select any of these values in the parameter editor, your design will not meet the calibration accuracy specification of -10 to 40%.

Resolution

Do not select these values.

This issue will be fixed in a future version of the Altera PHYLite for Parallel Interfaces IP core.
