How Do You Use a CANoe?

In this tutorial, we will explore how to use CANoe, a powerful software tool for developing, analyzing, and testing automotive systems based on the Controller Area Network (CAN) protocol.

Getting Started

Before diving into the details of using CANoe, let’s start with a brief overview of its capabilities. CANoe offers a comprehensive set of features to simulate, analyze, and test CAN-based systems. It allows you to create virtual networks and nodes, generate messages, monitor communication, and perform various tests.


To begin using CANoe, first download and install the software from Vector’s official website. Follow the installation instructions provided by the setup wizard. Once installed, you can launch CANoe from your desktop or start menu.

Creating a New Configuration

To start working on a new project in CANoe, you need to create a configuration file. Click on File -> New -> Configuration... Enter a name for your configuration file and choose an appropriate location to save it.

Adding Nodes

In order to simulate a networked system in CANoe, you need to add nodes. Nodes represent individual electronic control units (ECUs) or devices in the network. To add a node, right-click on the Network folder in the Configuration View, select Add Node., and provide relevant details such as node name and node type.

Sending Messages

In order to send messages between nodes in CANoe, you need to define message objects. To do this, select the desired node under the Network folder in the Configuration View, right-click on it and choose Add -> Message Object. Specify the message ID, data length, and other required parameters.


Once you have set up your network configuration and defined message objects, you can start simulating the communication between nodes. To begin the simulation, click on the Start Simulation button in the toolbar or select Simulation -> Start from the menu. You can monitor the communication in real-time using various monitoring panels available in CANoe.

Logging Messages

If you want to log the messages exchanged during simulation for later analysis, you can enable logging in CANoe. To do this, go to Simulation Setup -> Logging, select the desired logging options, and specify a path to save the log file.

Analyzing Communication

CANoe provides powerful analysis capabilities to help you understand and troubleshoot communication issues. You can use various analysis windows and panels to view message content, check signal values, analyze bus load, detect errors, and more.

Signal Display Window

The Signal Display window allows you to view and analyze individual signals within a message. You can plot signal values over time, analyze signal changes during different scenarios, and perform signal-related calculations.

Error Frame Window

In case of any error frames or bus-off conditions detected during communication, you can use the Error Frame window to investigate the root cause of these errors. It provides detailed information about error frames along with timestamps for further analysis.


In addition to simulation and analysis capabilities, CANoe also offers a wide range of testing features. You can create test cases using CAPL (CAN Access Programming Language), simulate test scenarios, and evaluate the behavior of your system under different conditions.

Test Case Editor

The Test Case Editor in CANoe allows you to define test cases for automated testing. You can specify the expected behavior, define pass/fail criteria, and execute the test cases against your simulated network.

Report Generation

After performing tests, you can generate detailed reports in various formats such as HTML or PDF. These reports provide a summary of test results, including passed and failed test cases, log files, and other relevant information.


CANoe is a powerful tool for developing, analyzing, and testing CAN-based systems. With its comprehensive set of features and user-friendly interface, it enables efficient development and validation of automotive networks. By following the steps outlined in this tutorial, you should now have a good understanding of how to use CANoe for your projects.

Remember to explore the extensive documentation provided by Vector to further enhance your knowledge and skills in using CANoe.
