Cyclone FPGA Family Data Sheet
Preliminary Information
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
Figure 6).
The
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.
