Topics

Startup and Connection

Set Up for HDL Cosimulation
To cosimulate your HDL code with a MATLAB or Simulink^®design, you must first:
金宝appEDA工具和硬件支持
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

创建一个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 an HDL simulator 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 theuse_instance_objargument for MATLAB functionsmatlabcpandmatlabtb.
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.
Use HDL Parameters in Cosimulation
Use Verilog parameters or VHDL generics in cosimulation.

Featured Examples

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.

Open Script

Cosimulation for Testing Filter Component Using MATLAB Test Bench

Run either Mentor Graphics® ModelSim®/Questasim® or Cadence® Xcelium® with MATLAB® in batch mode to test an HDL component using a MATLAB test bench, by using the HDL Verifier™ functionmatlabtb. The functionmatlabtbfacilitates this testing by feeding MATLAB-generated input data into the HDL component and feeding the output from the component back into MATLAB. When you generate complex waveforms in HDL, usingmatlabtbenables you to spend more time running tests than writing test waveforms.matlabtbalso reads the results, so the testing process can leverage MATLAB to apply data transformations to the output before plotting. For more information on writing test benches for cosimulation, see Create a MATLAB Test Bench.

Implement Filter Component of Oscillator in MATLAB

Implement a filter component for an HDL project in Mentor Graphics® ModelSim®/Questasim® or Cadence® Xcelium® by using MATLAB® the HDL Verifier™ functionmatlabcp. Instead of using HDL to model a complex component for use in an HDL project, you can usematlabcpto implement the component instead.matlabcpneeds a MATLAB function modeling the component behavior, along with an empty HDL component for input and output ports declared. These files are necessary asmatlabcpuses the empty component as a shell for communication between MATLAB and the HDL simulator, while the MATLAB function provides the functionality. Usingmatlabcpwhen verifying a single component allows MATLAB to simulate the various parts of the system, saving time and effort needed to create HDL code for testing. This approach shifts the focus onto generating tests and testing the component in question, creating a more efficient verification workflow. For information on creating the necessary files formatlabcp, see Create a MATLAB Component Function.

Implement Spectrum Display Component in MATLAB

Run MATLAB® with Mentor Graphics® ModelSim®/Questasim® to visualize the output of a larger HDL project, by using the HDL Verifier™ functionmatlabcp.matlabcpneeds a MATLAB function modeling the component behavior, along with an empty HDL component with input and output ports declared. These files are necessary asmatlabcpuses the empty HDL component as a shell for communication between MATLAB and the HDL simulator, while the MATLAB function provides the functionality of the component. Usingmatlabcpallows MATLAB to process the simulator data as the simulation progress, saving time needed to transform the original outputs into a visual format.
