To use the component instantiation method, you first have to declare the component in the declarative scope of where you want the module instance. That usually means in the VHDL file’s declarative region, but you can also define them in packages. The listing below shows the syntax of the component declaration.

We'll use a structural or hierarchical approach in the VHDL code, i.e. the architecture portion contains references to components MYAND2 and MYOR2. The entity/architecture pairs for these components will be described in a package file. 2. A component declaration statement in the top level file of the design hierarchy. 3. A component instantiation statement for each instance of the full adder component.

2016-01-29 2015-07-15 3.1 Syntactic Analysis. The first thing VHDL Mode does when indenting a line of code, is to analyze the line, determining the syntactic component list of the construct on that line. A syntactic component consists of a pair of information (in lisp parlance, a cons cell), where the first part is a syntactic symbol, and the second part is a relative buffer position. We'll use a structural or hierarchical approach in the VHDL code, i.e. the architecture portion contains references to components MYAND2 and MYOR2. The entity/architecture pairs for these components will be described in a package file.

In VHDL, you can create and use parameterized functions, including library of parameterized modules (LPM) functions supported by the Quartus II software.. To create a parameterized logic function in VHDL, the logic function's Entity Declaration must include a Generic Clause that lists all parameters (or "generics") used in the logic function and their optional default values.

Full adder trial layout. In Figure1 is reported a trial layout on ALTERA Quartus II using a Cyclone V FPGA. The signed full adder VHDL code presented above is pure VHDL RTL code so you can use it independently on every kind of FPGA or ASIC..

As generics have a limited scope, we can call the same VHDL component multiple times and assign different values to the generic. We can use generics to configure the behaviour of a component on the fly. VHDL was originally a hardware documentation language. Not a simulation nor a synthesising one. I agree that component instantiation is painfully verbose, but it's more readable in case the entity is not declared on the same source file. Also, on really big projects.
