FPGA-in-the-Loop

Test designs in real hardware

Creating an FPGA-in-the-loop link between the simulator and the board enables you to:

  • Verify HDL implementations directly against algorithms in Simulink® or MATLAB®.

  • Apply data and test scenarios from Simulink or MATLAB to the HDL design on the FPGA.

  • Integrate existing HDL code with models under development in Simulink or MATLAB.

Before you can use FPGA-in-the-loop (FIL) simulation, you must download the support package for your board. See Download FPGA Board Support Package. Alternatively, you can manually create custom board definition files for use with FIL simulation. See FPGA Board Customization.

After you download a board support package, select a simulation workflow. See FPGA-in-the-Loop Simulation Workflows. To learn how FIL simulation works, see FPGA-in-the-Loop Simulation.
