To save AC power, the Quartus II software forces all adder inputs low when ALM
adders are not in use.
Stratix IV LABs operate in high-performance mode or low-power mode. The
Quartus II software automatically chooses the appropriate mode for the LAB,
based on the design, to optimize speed versus leakage trade-offs.
Clocks represent a significant portion of dynamic power consumption due to their
high switching activity and long paths. The LAB clock that distributes a clock
signal to registers within an LAB is a significant contributor to overall clock power
consumption. Each LAB’s clock and clock enable signal are linked. For example, a
combinational ALUT or register in a particular LAB using the labclk1 signal also
uses the labclkena1 signal. To disable LAB-wide clock power consumption
without disabling the entire clock tree, use LAB-wide clock enable to gate the
LAB-wide clock. The Quartus II software automatically promotes register-level
clock enable signals to the LAB-level. All registers within the LAB that share a
common clock and clock enable are controlled by a shared, gated clock. To take
advantage of these clock enables, use a clock-enable construct in your HDL code
for the registered logic.
