Extended LUT Mode
Use extended LUT mode to implement a specific set of seven-input functions. The set
must be a 2-to-1 multiplexer fed by two arbitrary five-input functions sharing four
inputs.
extended LUT mode. In this mode, if the seven-input function is unregistered, the
unused eighth input is available for register packing.
Functions that fit into the template shown in
These functions often appear in designs as “if-else” statements in Verilog HDL or
VHDL code.
This input is available
