VHDL permet l'assemblage de "composants" ce qui constitue une description structurelle. Ce composant peut être appelé plusieurs fois dans un même circuit. Pour différencier ces mêmes composants, il est nécessaire de leur donner un nom d'" instance ".


In this case, there is no need to write twice the same module. It should be possible to parameterize the component during the instantiation. In order to implement parameterization of an entity VHDL introduce the generic clause. In the entity declaration, all the values that have to be customized can be passed using generic clause.

A digital system in VHDL consists of a design entitythat can contain other entities that are then considered components of the top-level entity. Each entity is modeled by an entity declarationand an architecture body. One can consider the entity declaration as the interface to the outside world that defines the input and output signals, while Every component we design in VHDL requires two separate parts - an entity and an architecture. The entity defines the external interface to the VHDL component we are designing, including a definition of the inputs and outputs.

The visible components are instantiated in the declarative part of the architecture body. architecture structural of mux4to1 is component and3 port( in1,in2,in3 :in 

The connections between these submodules are defined within the architecture of a top module. As you can see, a fulladder can be built with the help of two halfadders (module1, module2) and an OR gate (module3). In VHDL-93, the component name may be followed by the keyword is, for clarity and consistancy.
