## The vdpath & mega_lpm Libraries

The library of parameterized modules (LPM) 2.1.0 standard defines a set of parameterized functions and their corresponding representations in an EDIF netlist file. These logic functions allow you to create and functionally simulate an LPM-based design without targeting a specific device family. After the design is completed, you can target the design to any device family.

When the MAX+PLUS® II software processes projects that include Viewlogic-provided vdpath LPM functions, it uses functions from the Altera-provided mega_lpm library. This library includes all standard LPM functions except the truth table, finite state machine, and pad functions. Altera does not directly support the `lpm_ram_dq`, `lpm_ram_io`, and `lpm_rom` functions. Refer to Instantiating RAM & ROM Functions in Viewlogic Powerview Designs for instructions on instantiating RAM and ROM functions.

| Choose Megafunctions/LPM from the MAX+PLUS II Help menu for more information about LPM functions.
