Can I use the INPUT_TERMINATION .qsf assignment to assign an on-chip termination (OCT) to Transceiver REFCLK or Transceiver IO pins, in Stratix V, Arria V and Cyclone V devices?

Description

No you cannot use the INPUT_TERMINATION assignment to assign an on-chip termination (OCT) to transceiver pins on Stratix® V, Arria® V and Cyclone® V devices. Instead, you must use one of the following qsf assignments :

XCVR_GT_IO_PIN_TERMINATION (Stratix V GT transceiver IO pins ony)

XCVR_IO_PIN_TERMINATION (transceiver IO pins)

XCVR_REFCLK_PIN_TERMINATION (REFCLK pins)

Refer to the Altera Transceiver PHY IP Core User Guide (PDF) for more information on how to use these assignments.
Note that if you use an INPUT_TERMINATION assignment on the transceiver pins, it will be ignored by the Quartus® II software and the default termination option will be assigned to these pins.
