Synchronous process. 24 Sep 2020 See examples of the two ways to instantiate a VHDL module: component instantiation and entity instantiation (direct instantiation). Used to associate an Architecture with an Entity. – Package.

A VHDL file and the entity it contains have the same name.

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

A digital system in VHDL consists of a design entity that can contain other entities that are then considered components of the top- use ieee.std_logic_1164.all ; use Work.anu.all; entity Parity_Generator1 is port ( input_stream : in input; clk : in std_logic ; parity :out bit ); end Parity_Generator1;. Converts a VHDL entity definition into a component, instance or signal definitions , using the clipboard. Inspired by Sublime Text VHDL Utils.

I am using Entity-Architecture Pair Configuration instead of Lower-Level Configuration, so that I can decribe two architectures for the same entity in a single VHDL file, and then use Entity-Architecture Pair Configuration to configurate the entity in the upper-level VHDL file.
