Softwired LUT submode uses F4, F5 and F6 LUTs and internal PFU feedback routing to generate complex logic
functions up to three LUT-levels deep. Multiplexers can be independently congured to route certain LUT outputs to
the input of other LUTs. In this manner, very complex logic functions, some of up to 22 inputs, can be implemented
in a single PFU at greatly enhanced speeds.
It is important to note that an LUT output that is fed back for softwired use is still available to be registered or output
from the PFU. This means, for instance, that a logic equation that is needed by itself and as a term in a larger equa-
tion need only be generated once, and PLC routing resources will not be required to use it in the larger equation.
