Programmable Logic Cells
Softwired LUT submode uses F4 and F5 LUTs and internal PFU feedback routing to generate complex logic func-
tions up to three LUT-levels deep. Figure 3 shows multiplexers between the K
LUTs. These multiplexers can be independently configured to route certain LUT outputs to the input of other LUTs.
In this manner, very complex logic functions, some of up to 21 inputs, can be implemented in a single PFU at
greatly enhanced speeds.
Figure 5 shows several softwired LUT topologies. In this figure, each circle represents either an F4 or F5 LUT. 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
equation need only be generated once and PLC routing resources will not be required to use it in the larger equa-
tion.
