This section provides some basic hints on how to use HDL Coder functionality in combination with Simulink-programmable FPGA I/O modules and Xilinx FPGA Synthesis software.


Before installing the HDL Coder Integration Package, please make sure to have the following Software installed:

  • MATLAB Release R2021b

  • Simulink

  • MATLAB Coder

  • Simulink Coder

  • Simulink Real-Time

  • HDL Coder

  • Xilinx Vivado Design Suite 2020.1

  • Speedgoat I/O Blockset 9.3.0 or later


Download the latest HDL Coder Integration Package (HCIP) from the downloads section of the Speedgoat Customer Portal. If the HCIP is not available, please contact Speedgoat Support.

Installation Steps

To install the Speedgoat HCIP, proceed as follows:

  1. Start MATLAB and navigate to the previously downloaded archive file

  2. Double-click the archive file in MATLAB to unzip it

  3. Enter the following command in the MATLAB Command Window:

    >> hdlCoder_integration_package_installer

FPGA Synthesis Software Settings

To use the HDL Coder functionality in combination with the Xilinx FPGA Synthesis software, use the hdlsetuptoolpath command before opening HDL Workflow Advisor to properly configure the system environment. Additional information is available at set up system environment to access FPGA synthesis software. If you use Speedgoat Simulink-programmable FPGA I/O modules together with HDL Coder from MathWorks, the correct Xilinx software version must be installed:

Xilinx Vivado Design Suite 2020.1

I/O ModuleSoftwareComments

Xilinx Vivado Design Suite 2020.1

Alternatively, the free-of-charge WebPACK version can be used as well.









Xilinx Vivado Design Suite 2020.1


Xilinx Vivado Design Suite 2020.1

Alternatively, the free-of-charge WebPACK version can be used as well.

The following command sets the synthesis tool path to point to an installed Xilinx "Vivado Design Suite HLx Edition" (Vivado HL Design Edition).

>> hdlsetuptoolpath('ToolName','Xilinx Vivado','ToolPath','C:\Xilinx\Vivado\2020.1\bin\vivado.bat');

Optionally, hdlsetuptoolpath commands can be added to the MATLAB startup.m script so that they are automatically executed when MATLAB starts.

We recommend installing the Xilinx Design Edition. However, if you choose to use Xilinx System Edition (incl. System Generator), ensure to not select any MATLAB release during the System Generator installation, as this may lead to conflicts. The link to the MATLAB release can later be set using hdlsetuptoolpath, as described above.

For previous MATLAB releases find the corresponding Xilinx Vivado version dependencies in previous versions.
