Register Feedback
preset/load, synchronous clear, synchronous load, and clock enable
control for the register. These LAB-wide signals are available in all LE
modes. The addnsub control signal is allowed in arithmetic mode.
The Quartus II software, in conjunction with parameterized functions
such as library of parameterized modules (LPM) functions, automatically
chooses the appropriate mode for common functions such as counters,
adders, subtractors, and arithmetic functions. If required, you can also
create special-purpose functions that specify which LE operating mode to
use for optimal performance.
Normal Mode
The normal mode is suitable for general logic applications and
combinatorial functions. In normal mode, four data inputs from the LAB
local interconnect are inputs to a four-input LUT (see
Quartus II Compiler automatically selects the carry-in or the data3
signal as one of the inputs to the LUT. Each LE can use LUT chain
connections to drive its combinatorial output directly to the next LE in the
LAB. Asynchronous load data for the register comes from the data3
input of the LE. LEs in normal mode support packed registers.
