The Quartus II software and supported third-party synthesis tools, in
conjunction with parameterized functions such as the library of
parameterized modules (LPM) functions, automatically choose the
appropriate mode for common functions such as counters, adders,
subtractors, and arithmetic functions.
Normal Mode
The normal mode is suitable for general logic applications and
combinational functions. In this mode, up to eight data inputs from the
LAB local interconnect are inputs to the combinational logic. The normal
mode allows two functions to be implemented in one Stratix III ALM, or
an ALM to implement a single function of up to six inputs. The ALM can
support certain combinations of completely independent functions and
various combinations of functions that have common inputs.
shows the supported LUT combinations in normal mode.
