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. SeeDownload FPGA Board Support Package. Alternatively, you can manually create custom board definition files for use with FIL simulation. SeeFPGA Board Customization.

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

Accelerating Communications System Simulation Using FPGA-in-the-Loop

Uses FPGA-in-the-Loop (FIL) simulation to accelerate part of a communications system. The application uses the Viterbi Algorithm to decode a convolutional encoded random stream that is BPSK modulated, sent through an AWGN channel, and then demodulated. Using a sample-by-sample approach leads to a modest speedup over normal Simulink® simulation, while using the "Process as Frames" option leads to further speedup.

Open Model

Algorithm Verification with a FIL Source Block

Verify an HDL design quickly and efficiently using FPGA-in-the-Loop (FIL). The test bench is synthesized together with the Design Under Test (DUT), the result is downloaded to an FPGA board, and the test is run with FIL. Using FIL for this process enables high speed generation and processing of test stimulus, with results returned to Simulink for analysis. This example executes these tasks for an image processing use case.
