Power consumption also affects thermal management. Stratix IV devices offer a TSD
feature that self-monitors the device junction temperature and can be used with
external circuitry for other activities, such as controlling air flow to the Stratix IV
FPGA.

The following sections describe Stratix IV programmable power technology.
Stratix IV devices offer the ability to configure portions of the core, called tiles, for
high-speed or low-power mode of operation performed by the Quartus II software
without user intervention. Setting a tile to high-speed or low-power mode is
accomplished with on-chip circuitry and does not require extra power supplies
brought into the Stratix IV device. In a design compilation, the Quartus II software
determines whether a tile must be in high-speed or low-power mode based on the
timing constraints of the design.
For more information about how the Quartus II software uses programmable power
technology when compiling a design, refer to
FPGAs.
A Stratix IV tile can consist of the following:

All blocks and routing associated with the tile share the same setting of either
high-speed or low-power mode. By default, tiles that include DSP blocks or memory
blocks are set to high-speed mode for optimum performance. Unused DSP blocks and
memory blocks are set to low-power mode to minimize static power. Clock networks
do not support programmable power technology.
With programmable power technology, faster speed grade FPGAs may require less
power because there are fewer high-speed MLAB and LAB pairs, when compared
with slower speed grade FPGAs. The slower speed grade device may have to use
more high-speed MLAB and LAB pairs to meet performance requirements, while the
faster speed grade device can meet performance requirements with MLAB and LAB
pairs in low-power mode.
