  We can control the structure and timing of an entity using generic constants. For example, in the following VHDL description generic constant N is used to specify the number of bits for the adder. During the simulation or the synthesis process, the actual value for each generic constant can be changed. entity ADDER is generic (N : INTEGER := 4 ;

  A VHDL entity is simply a declaration of a module’s inputs and outputs, i.e. its external interface signals or ports. A VHDL architecture is a detailed description of the module’s internal structure or behavior. You can think of the entity as a “wrapper” for the architecture, hiding the details of what’s ...

  Component instantiation is a concurrent statement that can be used to connect circuit elements at a very low level or most frequently at the top level of a design. A VHDL design description written exclusively with component instantiations is known as Structural VHDL. Structural VHDL defines behavior by describing how components are connected.
