1. Intel® Stratix® 10 LAB and ALM Overview
The logic array block (LAB) is composed of basic building blocks known as adaptive logic modules (ALMs). You can configure the LABs to implement logic functions, arithmetic functions, and register functions.
You can use a quarter of the available LABs in the Intel® Stratix® 10 devices as memory LABs (MLABs). Certain devices may have a higher MLAB ratio.
The Intel® Quartus® Prime software and other supported third-party synthesis tools automatically choose the appropriate mode for common functions such as counters, adders, subtractors, and arithmetic functions.
