LAB Control Signals
Each LAB contains dedicated logic for driving control signals to its ALMs.
The control signals include three clocks, three clock enables, two
asynchronous clears, synchronous clear, asynchronous preset/load, and
synchronous load control signals. This gives a maximum of 11 control
signals at a time. Although synchronous load and clear signals are
generally used when implementing counters, they can also be used with
other functions.
Each LAB can use three clocks and three clock enable signals. However,
there can only be up to two unique clocks per LAB, as shown in the LAB
control signal generation circuit in
enable signals are linked. For example, any ALM in a particular LAB
using the labclk1 signal also uses labclkena1. If the LAB uses both
the rising and falling edges of a clock, it also uses two LAB-wide clock
signals. De-asserting the clock enable signal turns off the corresponding
LAB-wide clock.
Each LAB can use two asynchronous clear signals and an asynchronous
load/preset signal. By default, the Quartus II software uses a NOT gate
push-back technique to achieve preset. If you disable the NOT gate
push-up option or assign a given register to power up high using the
Quartus II software, the preset is achieved using the asynchronous load
