logic function Definition

A primitive, Intel^® FPGA IP, macrofunction, or state machine, which may be represented as either a name or a symbol in a design file.

A logic function can be a top-level design entity, which is a logic function that is the root of a design hierarchy, or a lower-level logic function (or, subdesign). A logic function can instantiate any number of lower-level logic functions, and is the parent for the lower-level logic functions.

The following logic function types are supported in the Quartus^® Prime software:

• AHDL subdesigns
• Block Design (.bdf) File entities
• EDIF cells inside EDIF designs
• Verilog HDL modules
• VHDL entity-architecture design units

Logic functions are also referred to as design entities or entities.
