Look-Up Tables (LUTs) are one of the fundamental building blocks used inside Field-Programmable Gate Arrays (FPGAs) to implement digital logic. A LUT stores predefined output values for every possible combination of its input signals, allowing an FPGA to reproduce Boolean logic functions without requiring a dedicated physical circuit for every operation. When an FPGA design…
