LE Operating Modes
LE Operating Modes
Normal Mode

In addition to the three general routing outputs, LEs in a LAB have register chain
outputs, which allows registers in the same LAB to cascade together. The register
chain output allows the LUTs to be used for combinational functions and the registers
to be used for an unrelated shift register implementation. These resources speed up
connections between LABs while saving local interconnect resources.
Cyclone III device family LEs operate in the following modes:
■
■
LE operating modes use LE resources differently. In each mode, there are six available
inputs to the LE. These inputs include the four data inputs from the LAB local
interconnect, the LE carry-in from the previous LE carry-chain, and the register chain
connection. Each input is directed to different destinations to implement the desired
logic function. LAB-wide signals provide clock, asynchronous clear, synchronous
clear, synchronous load, and clock enable control for the register. These LAB-wide
signals are available in all LE modes.
The Quartus
functions, such as counters, adders, subtractors, and arithmetic functions, in
conjunction with parameterized functions such as the library of parameterized
modules (LPM) functions. You can also create special-purpose functions that specify
which LE operating mode to use for optimal performance, if required.
Normal mode is suitable for general logic applications and combinational functions.
In normal mode, four data inputs from the LAB local interconnect are inputs to a
four-input LUT
carry-in (cin) or the data3 signal as one of the inputs to the LUT. LEs in normal
mode support packed registers and register feedback.
