MATLAB VHDL Simulation

MATLAB VHDL Simulation design are developed tailored to your project needs. With the help of diverse tools and methods, VHDL (VHSIC Hardware Description Language) models can be easily modeled in MATLAB. To co-simulate VHDL and MATLAB code, we must use a VHDL simulator or implement MATLAB with ModelSim, which is one of the general methods. As we have all latest research methodologies and best developers we ensure your projects success. To configure and conduct co-simulation of MATLAB and VHDL, a detailed guide is offered below:

Measures for MATLAB and VHDL Co-Simulation

1. Organize VHDL Code: Our VHDL code and testbenches should be scripted and organized properly. We have to verify our VHDL code, whether it is modeled correctly and examined for improper syntax.
2. Configure ModelSim: Among users, one of the prevalent VHDL simulators is ModelSim. On our system, we must assure, if we installed and set up the ModelSim. For MATLAB synthesization, ModelSim is considered as a general approach. We can utilize other simulators such as Altera Quartus, Xilinx Vivado and more.
3. MATLAB Setup: MATLAB is required to be installed and initialized on our system. Especially for co-simulation, MATLAB should contain the required toolkits and support packages.
4. Design VHDL Testbench: To simulate the features, develop a Testbench for our VHDL code. For the purpose of interacting with MATLAB, we can use Testbench.
5. Co-Simulation Configuration: In order to interact with the VHDL simulator (ModelSim), the co-simulation platform is meant to be initialized in MATLAB.

Instance of Workflow

1. Develop VHDL Code

A VHDL file (example.Vhd1) needs to be developed.

library ieee;

use ieee.std_logic_1164.all;

entity example is

port (

clk : in std_logic;

rst : in std_logic;

data_in : in std_logic_vector(7 downto 0);

data_out : out std_logic_vector(7 downto 0)

);

end example;

architecture Behavioral of example is

begin

process(clk, rst)

begin

if rst = ‘1’ then

data_out <= (others => ‘0’);

elsif rising_edge(clk) then

data_out <= data_in;

end if;

end process;

end Behavioral;

We must develop a Testbench (example_ tb. Vhd1)

library ieee;

use ieee.std_logic_1164.all;

entity example_tb is

end example_tb;

architecture Behavioral of example_tb is

signal clk : std_logic := ‘0’;

signal rst : std_logic := ‘1’;

signal data_in : std_logic_vector(7 downto 0) := (others => ‘0’);

signal data_out : std_logic_vector(7 downto 0);

component example

port (

clk : in std_logic;

rst : in std_logic;

data_in : in std_logic_vector(7 downto 0);

data_out : out std_logic_vector(7 downto 0)

);

end component;

begin

uut: example

port map (

clk => clk,

rst => rst,

data_in => data_in,

data_out => data_out

);

clk <= not clk after 10 ns;

process

begin

rst <= ‘1’;

wait for 20 ns;

rst <= ‘0’;

data_in <= “00000001”;

wait for 20 ns;

data_in <= “00000010”;

wait for 20 ns;

data_in <= “00000100”;

wait;

end process;

end Behavioral;

2. Configure ModelSim

It is required to assure that, whether ModelSim is installed and initialized on our system. To compile and simulate our VHDL code, we can utilize ModelSim GUI.

vcom example.vhdl

vcom example_tb.vhdl

vsim example_tb

3. MATLAB Setup

For HDL and co-simulation, assure whether we installed MATLAB with required toolkits. HDL Verifier toolbox can be required for our project.

4. VHDL Testbench

As a means to simulate the VHDL design within the MATLAB function, a Testbench should be developed and deployed.

% Create a MATLAB script for co-simulation

vhdlSystem = ‘example_tb’; % Name of your VHDL testbench

vsim(‘tclstart’, ‘do sim.do’);

vsim(vhdlSystem);

% Define signals and their mapping

hdl_sim(‘addwave’, ‘uut/clk’, ‘uut/rst’, ‘uut/data_in’, ‘uut/data_out’);

vsim(‘run’, 1000); % Run simulation for 1000 time units

% Use MATLAB to generate stimuli and capture results

data_in = [1, 2, 4]; % Example input data

data_out = zeros(size(data_in));

for i = 1:length(data_in)

hdl_sim(‘force’, ‘uut/data_in’, dec2bin(data_in(i), 8));

hdl_sim(‘run’, 20); % Run for 20 time units

data_out(i) = bin2dec(hdl_sim(‘peek’, ‘uut/data_out’));

end

disp(‘Simulation results:’);

disp(data_out);

5. Co-Simulation Configuration

To interact with the VHDL simulator, we need to set up the MATLAB. For communicating with ModelSim, the HDL Verifier toolkit offers functions such as vcom, vsim and hdlverifier.

% Example MATLAB script to perform co-simulation with ModelSim

vsim(‘tclstart’, ‘do sim.do’);

vsim(‘example_tb’);

% Adding signals to the waveform

vsim(‘addwave’, ‘uut/clk’);

vsim(‘addwave’, ‘uut/rst’);

vsim(‘addwave’, ‘uut/data_in’);

vsim(‘addwave’, ‘uut/data_out’);

% Running the simulation

vsim(‘run’, 1000); % Run simulation for 1000 time units

% Example: changing signal values and running the simulation

hdlforce(‘example_tb/uut/data_in’, ‘00000001’);

vsim(‘run’, 20);

data_out1 = hdlpeek(‘example_tb/uut/data_out’);

hdlforce(‘example_tb/uut/data_in’, ‘00000010’);

vsim(‘run’, 20);

data_out2 = hdlpeek(‘example_tb/uut/data_out’);

disp([‘Data Out 1: ‘, data_out1]);

disp([‘Data Out 2: ‘, data_out2]);
