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 ArriaIIGX 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.
