Tutorial: Using the logic estimator
9.6 Using ALU Mapping
One of the new features introduced in DK 3.0 was ALU Mapping. This is only supported on FPGA
devices which contain embedded ALU primitives, such as multipliers or MAC units. When this feature is
enabled, DK will automatically target embedded ALUs, making use of them where they will result in the
biggest increase in performance or reduction in logic area. It is possible to limit the number of ALUs
which will be used, if some of them are being specifically used for other purposes. The settings for ALU
Mapping are accessed through the
Project->Settings menu, from which you must select the Synthesis tab,
as shown below:
