Topics

Startup and Connection

Set Up for HDL Cosimulation

To cosimulate your HDL code with a MATLAB or Simulink® design, you must first:

Supported EDA Tools and Hardware

List of supported third-party EDA software and FPGA boards.

Set Up MATLAB-HDL Simulator Connection

Cosimulation requires a connection between MATLAB and your HDL simulation tool.

TCP/IP Socket Ports

Provides some direction for choosing TCP/IP socket ports.

Cross-Network Cosimulation

Provides instructions for performing cosimulation across a local network.

Run MATLAB-HDL Cosimulation

Run your test bench or component, including the cosimulation of your HDL module.

Cosimulation with System Object

Create a MATLAB System Object

You can verify HDL modules using the HDL Cosimulation System object™.

Verify Viterbi Decoder Using MATLAB System Object and HDL Simulator

This example shows you how to use MATLAB® System objects and Mentor Graphics® ModelSim®/QuestaSim® or Cadence® Incisive®/Xcelium® to cosimulate a Viterbi decoder implemented in VHDL.

Import HDL Code for MATLAB System Object

Generate a MATLAB System object to cosimulate your HDL code.

Cosimulation with Function

Import HDL Code for MATLAB Function

Generate a MATLAB function to cosimulate your HDL code.

Test Bench and Component Function Writing

This section explains how you use the use_instance_obj argument for MATLAB functions matlabcp and matlabtb.

Verify Raised Cosine Filter Design Using MATLAB

This tutorial guides you through the basic steps for setting up an HDL Verifier™ cosimulation that uses MATLAB and the HDL Simulator.

Automatic Verification

Automatic Verification of Generated HDL Code from MATLAB

Verify generated HDL code using a generated cosimulation script.

Verify Code with HDL Test Bench (HDL Coder)

Simulate the generated HDL design under test (DUT) with test vectors from the test bench using the specified simulation tool.

All Cosimulation

HDL Cosimulation

The HDL Verifier software consists of MATLAB functions, a MATLAB System object, and a library of Simulink blocks, all of which establish communication links between the HDL simulator and MATLAB or Simulink.

Prepare to Import HDL Code for Cosimulation

Prepare for cosimulation and choose whether to cosimulate your HDL code as a function, System object, or block.

Supported Data Types

If your HDL application needs to send HDL data to a MATLAB function, you may first need to convert the data to a type supported by MATLAB and the HDL Verifier software.

Race Conditions in HDL Simulators

Describes ways to avoid race conditions in hardware cosimulations with MATLAB and Simulink software.

Featured Examples

Testing a Filter Component in MATLAB®

Testing a Filter Component in MATLAB®

How MATLAB® can be used as a test bench for an HDL component. We compile an HDL low pass filter and then test it using matlabtb.

Batch Mode Cosimulation for Testing a Filter Component

Batch Mode Cosimulation for Testing a Filter Component

Illustrates running ModelSim® or Incisive® HDL Simulator in batch mode to test an HDL component with a MATLAB® test bench. In this demonstration, we compile an HDL low-pass filter - designed and generated with the Filter Design HDL Coder™ - and then test its response using the HDL Verifier™ function matlabtb. The entire cosimulation is executed in batch mode.

Implementing the Filter Component of an Oscillator in MATLAB®

Implementing the Filter Component of an Oscillator in MATLAB®

This examples shows how MATLAB® can be used to implement a filter component used in an HDL model. The example compiles a VHDL/Verilog oscillator, defines a filter component that is modeled using MATLAB, and runs the HDL simulation. This example requires a temporary directory to generate a working ModelSim VHDL or Incisive Verilog project. After creating the HDL project, this example starts the HDL simulator (this requires access to ModelSim/Incisive from the command line). This example uses shared memory to complete the link and therefore requires the HDL simulator to be on the same computer as MATLAB. Once the project is compiled, the simulation can be run from within ModelSim/Incisive.

Manchester Receiver

Manchester Receiver

The Manchester Receiver example shows how to use the HDL Verifier™ to design, test, and verify a VHDL Manchester Receiver model with clock recovery capabilities.

Implementing a Spectrum Display Component in MATLAB®

Implementing a Spectrum Display Component in MATLAB®

MODSIMSPECDISP shows how MATLAB® can be used to implement a VHDL component that is used to display the spectrum of a signal from a VHDL project in ModelSim®. This example compiles a VHDL source containing a frequency hopping sine wave feeding a lowpass filter and defines a spectrum display component in MATLAB. The MATLAB component buffers its inputs into frames of 128 samples and displays the spectra of the unfiltered and filtered signals as the simulation is running. This example requires a temporary working directory to generate a working ModelSim VHDL project. After creating the VHDL project, this example starts ModelSim (this requires access to ModelSim from the command line). This example uses shared memory to complete the link and therefore requires ModelSim to be on the same computer as MATLAB. Once the project is compiled, the simulation can be run from within ModelSim.
