Syntax architecture ArchitectureName of EntityName is. 19 Aug 2018 1.1 Entity. As we mentioned in the previous paragraph, entity part of the VHDL program describes the I/O ports of an electronic circuit. A port can entity entity_name is generic (generic_list); port (port_list); end entity_name; The top-level entity in a simulateable VHDL model is usually "empty", i.e. has no Entity Declarations.

Main role of entity declaration is to define these ports – their names, types, width and direction. Basically entity declaration shows how module is seen by other modules.

This example describes how to create a hierarchical design using VHDL. The top-level design, called top.vhd, implements an instance of the function logic.vhd. In the top.vhd file, a component for the logic function is declared inside the architecture in which it is instantiated. The Component Declaration defines the ports of the lower-level
