Altera PHYLite for Parallel Interfaces IP Core GUI Shows Unsupported Input OCT Values - 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. Custom Fields values: ['novalue'] Troubleshooting novalue True ['PLL'] ['FPGA Dev Tools Quartus® Prime Software Pro'] novalue 16.0 ['Programmable Logic Devices'] ['novalue'] ['novalue'] ['novalue']
