A logic function that uses parameters to achieve scalability, adaptability, and efficient silicon implementation. Quartus^® II supports a variety of parameterized functions (also called "parameterized modules"), including functions belonging to the Library of Parameterized Modules (LPM).

LPM functions provide architecture-independent design entry for all Quartus II-supported devices. The Quartus II Compiler includes built-in compilation support for LPM functions used in schematic, AHDL, VHDL, Verilog HDL, and EDIF input files.
