A port map is a VHDL construction that maps signals in an architecture (actual part) to ports on an instance (formal part) within that architecture. Port maps can be in a component instantiation, in a block or in a configuration. These connections can be coded via named associations as well as via positional associations. Syntax:

constant clk_period : time := 10 ns; BEGIN -- instantiate the Unit Under Test (UUT) uut: entity work.six_order_fir_filter PORT MAP ( clk => clk,

The instantiation statement connects a declared component to signals in the architecture. The instantiation has 3 key parts: • Label - Identiﬁes unique instance of component • Component Type - Select the desired declared component • Port Map The port names from the component declaration, also called “formals”, are associated with an arrow ’⇒’ with the signals of the entity (“actuals”). In the example, the output port SUM is declared third in the component declaration. In the port map statement, however, this port is connected to the signal W_SUM in the second place. 2016-05-29 VHDL Syntax Reference (Author's Note: This document contains a reference on VHDL syntax that you may encounter during this course.It is by no means complete.There are many references available online that you may check for more complete material. The following is intended simply to provide a quick and concise reference on commonly used syntax in VHDL.) Port map is the part of the module instantiation where you declare which local signals the module’s inputs and outputs shall be connected to. In previous tutorials in this series we have been writing all our code in the main VHDL file, but normally we wouldn’t do that.

We map signals to ports using a keyword port map. uut : adder_ff port map( a =>a, b =>b, cin => cin, sum =>sum, carry => carry); Then we start injecting input values to signal. Port map is a concurrent statement. it is used to refer existing hardware ports. while, process contains sequential statements which takes very less time to give the results.that's why port map is Dealing with unused signals in VHDL Using open and others appropriately. It's often the case when writing VHDL that some of your FPGA signals will not be used.

This is followed by information on how to create the project using the Xilinx tools.

The example above shows the previously defined design entity AOI being used as a component within another, higher level design entity MUX2I, to create a design hierarchy with two levels. The design entity MUX2I also contains a second component, named INV. In order to write the VHDL for this circuit, we need to cover two Description: A generic map gives the value to a generic.

Ex. A1: adder port map (v,w,x,y,z) v,w, and y must be bit_vectors, y and z bits The signals which we use in our VHDL port map, such as in the example above, must be declared before they can be used. As VHDL is a strongly typed language, the signals we use in the port map must also match the type of the port they connect to.

Think of this process as using functions in high level programming languages such as C++, Where the component is the function and port mapping is calling the function to the main program.

This allows VHDL tools Description: A port map maps signals in an architecture to ports on an instance within that architecture. Port maps can also appear in a block or in a configuration There is a reserved keyword in VHDL, open which can be used in place of a signal name when you do the port mapping.
