This chapter describes the features of the logic array block (LAB) in the Cyclone
The LAB is composed of basic building blocks known as adaptive logic modules (ALMs) that you can
configure to implement logic functions, arithmetic functions, and register functions.
You can use a quarter of the available LABs in the Cyclone V devices as a memory LAB (MLAB).
®
The Quartus II software and other supported third-party synthesis tools, in conjunction with parameterized
functions such as the library of parameterized modules (LPM), automatically choose the appropriate mode
for common functions such as counters, adders, subtractors, and arithmetic functions.
This chapter contains the following sections:

LAB
The LABs are configurable logic blocks that consist of a group of logic resources. Each LAB contains dedicated
logic for driving control signals to its ALMs.
MLAB is a superset of the LAB and includes all the LAB features.
