The Quartus II software sets unused device resources in the design to low-power
mode to reduce static and dynamic power. It also sets the following resources to
low-power mode when they are not used in the design:
■
■
■
If a phase-locked loop (PLL) is instantiated in the design, asserting the areset pin
high keeps the PLL in low-power mode.

considerations can add to the permutations to give you flexibility in designing your
system.
Table 13–1. Programmable Power Capabilities in Stratix IV Devices
This section describes the different external power supplies required to power
Stratix IV devices. You can supply some of the power supply pins with the same
external power supply, provided they have the same voltage level.
For power supply pin connection guidelines and power regulator sharing, refer to the
Stratix IV GX and Stratix IV E Device Family Pin Connection
For each Altera recommended power supply’s operating conditions, refer to the
and Switching Characteristics for Stratix IV Devices
