The LAB consists of 16 logic elements (LE) and a LAB-wide control block. An LE is the smallest unit of logic in the Cyclone® 10 LP device architecture. Each LE has four inputs, a four-input look-up table (LUT), a register, and output logic. The four-input LUT is a function generator that can implement any function with four variables.
