Introduction

In this tutorial we show how a to write a

Matlab function code and covert it to a VHDL

code. We will write a simple multiplexer

code for the purpose of illustration.

• Create a new Project in Matlab and create a Function File named mux_func(a,b,sel)

• Save the function file with name mux_func.m

Step1: Create a Function File

• Create another script file enter the code as shown

• Save the script file with some name like test.m

• This script file is used to test the function mux_func that was created earlier

Step 2: Create a script file

• Run the test file to ensure that the function works as intended

• To do this just click on the Run button in the Editor tab

Step 3: Run the Test file

Run Editor

Select the APPS tab and click on the HDL Coder

Step 4: Select HDL Coder

Step 5: Specify Project Name to your

HDL Code Project

Once you click the HDL coder in step 4 a window will pop up just like the one below where you can specify a project name for you HDL coder project with the name of your choosing. In this case mux_hdl was given as project name

Step 6: Select File to Convert

The HDL Coder screen will open as shown

Browse for the Files

Click here to Add MATLAB function

Add the function file mux_func to convert

Browse and select the mux_func function file

Click on WorkFlow
