Power Rail

Description

VCC voltage

Displays the voltage that you supply to the VCC power rail.

VCCCB voltage

Displays the voltage that you supply to the VCCCB power rail.

VCCA_PLL voltage

Displays the voltage that you supply to the VCCA_PLL power rail.

VCCD_PLL voltage

Displays the voltage that you supply to the VCCD_PLL power rail.

VCCA voltage

Displays the default voltage of the VCCA power rail supply, which is applied if the transceivers are powered.

VCCH_GXB voltage

Displays the default voltage of the VCCH_GXB power rail supply, which is applied if the transceivers are powered.

VCCL_GXB voltage

Displays the default voltage of the VCCL_GXB power rail supply, which is applied if the transceivers are powered.

VCCIO voltage

Displays the method you can use to set the VCCIO voltage. For Arria®IIGX devices, you configure the VCCIO voltage with pin assignments.

Transceiver power

Allows you to power off the transceivers. This setting affects the VCCA, VCCH_GXB, and VCCL_GXB power rails.

  • Opportunistically power off— If the transceivers are unused, setting this option directs the PowerPlay® Power Analyzer to consider the transceivers powered down.
  • Power on— Directs the PowerPlay® Power Analyzer to consider the transceivers powered regardless of their use.
