Figure 1–7. ALM in Normal Mode
Note to
(1) Combinations of functions with fewer inputs than those shown are also supported. For example, combinations of
Normal mode provides complete backward-compatibility with four-input LUT
architectures.
For the packing of 2 five-input functions into one ALM, the functions must have at
least two common inputs. The common inputs are dataa and datab. The combination
of a four-input function with a five-input function requires one common input (either
dataa or datab).
In the case of implementing 2 six-input functions in one ALM, four inputs must be
shared and the combinational function must be the same. In a sparsely used device,
functions that could be placed in one ALM may be implemented in separate ALMs by
the Quartus II software to achieve the best possible performance. As a device begins
to fill up, the Quartus II software automatically uses the full potential of the Stratix V
ALM. The Quartus II Compiler automatically searches for functions using common
inputs or completely independent functions to be placed in one ALM to make efficient
use of device resources. In addition, you can manually control resource use by setting
location assignments.
functions with the following number of inputs are supported: 4 and 3, 3 and 3, 3 and 2, and 5 and 2.
