VHDL entity and architecture descriptions include: VHDL Recursive Component Instantiation The entity declaration can also declare VHDL generics.
In VHDL -93., an entity-architecture pair can be instantiated directly. In this case a component declaration is not required. This is more compact, but does not allow the flexibility of configuration. Component instantiation is like plugging a hardware component into a socket in a board (Fig.
Imagine you need to write 2 RAM modules. VHDL generic example for two similar RAM entity VHDL Entity Declaration. We use the entity to define the external interface to the VHDL component we are designing. This mainly involves defining the inputs and outputs, although we can provide further configuration details as well. The syntax below shows how we declare an entity in VHDL. University of HartfordByXavier Flowers & Merlene BuchananSaeid Moslehpour The Quartus10.0 altera_mf altshift_taps_component was missing a VHDL generic “ram_block_type”.

A component must be declared before it is instantiated.
The first one creates a simple 2-bit ripple carry adder that made up of just two full adders (it can add together any two-bit inputs). The second example uses a generic that creates a ripple carry adder that accepts as an input parameter the WIDTH of the inputs. Therefore, it is scalable for any input widths. This VHDL project presents a simple VHDL code for a comparator which is designed and implemented in Verilog before.Full VHDL code together with test bench for the comparator is provided. The design for the comparator based on the truth table and K-map are already presented here.There are two 2-bit inputs A and B to be compared. Three output signals are A_less_B (1 if A < B, else 0), A_equal_B
We will also use component instantiating method and structural VHDL coding in Xilinx .

13.1.3 Packaging Components Let us now turn to the issue of design management for large projects and see how we can make management of large libraries of entities easier using packages and components. Digital system design: many VHDL components available, some as parameterized VHDL code (for re-usability). So, when instantiating these components into a top-level file, we both map the signals (port map) and the parameters (generic map). StopWatch design: We need to instantiate six counters.

Simplified Syntax. label : [ component ] component_name VHDL Components A VHDL component describes predefined logic that can be stored as a package declaration in a VHDL library and called as many times as necessary in a program. You can use components to avoid repeating the same code over and over within a program.

In this case, you can now use your signal as v_normal_in_sig(i) to connect to the ith generated instanciation of your entity/component. Note that if you are using VHDL-2008, you can do the following instead type vector_array is array (natural range <>) of std_logic_vector; signal v_normal_in_sig : vector_array(7 downto 0)(15 downto 0);
This tutorial covers the various aspects of component instantiations in VHDL through a very simple example. It covers also the use of generics and constants.
In VHDL-93, the component name may be followed by the keyword is, for clarity and consistancy. also the keywords end component may be followed by a repetition of the component name: component component_name is port (port list); end component component_name;
