The 3 Most Common CANoe Examples with Tips for Users

CANoe offers many application areas and functionalities. It´s not easy to get an overview of this. To simplify your work, we will guide you here through 3 of the most common CANoe application examples. You will receive simple yet effective tips:

  • Typical pitfalls & how to avoid them
  • What your optimal CANoe tool environment might look like

Let´s start: What is your task?

  1. Developing ECUs
  2. Automated ECU testing
  3. System validation

1. Developing ECUs

You develop an ECU and need the associated remaining bus simulation. You monitor the network traffic and make use of the comprehensive analysis possibilities of CANoe, such as the Trace Window or Graphics Window or Logging. You also stimulate the network traffic or selectively intervene in the remaining bus simulation.

 

Avoid these pitfalls:

A remaining bus simulation in the form of handwritten code is error-prone and very maintenance-intensive.

Changes in the communication matrix lead to inconsistencies of the remaining bus simulation.

What your Vector solution looks like:

Configure in CANoe your OEM specific Interaction Layer that automatically takes over the complete send behaviour of the network.

2. Automated ECU Testing

You develop ECUs and want to test their functions using automated testing. In doing so, you bring your system to its limits. You stimulate ECU functions, selectively inject errors, and monitor the ECU reactions on your network.

 

Avoid these pitfalls:

The tests are not reproducible or are poorly reproducible as soon as they are performed interactively and manually.

The non-automated test execution ties up scarce resources or important staff.

Manually created test protocols can be further processed incompletely or poorly.

What your Vector solution looks like:

Create your tests with vTESTstudio. With this tool, you can either select predefined test primitives or develop your own.  CANoe hereby performs as a tool for automatic test execution and generates an extensive test protocol. The tests can be reproduced at any time and you can adjust the appearance of your test protocol to your needs.

3. System Validation

You want to assure the complete system functionality. It is necessary here to provide the corresponding system environment for your System Under Test (SUT) and to incorporate analog and digital inputs and outputs in the test.

 

Avoid these pitfalls:

Missing time synchronization between network events and stimulation or measurement of the inputs and outputs.

The specific signal conditioning of the inputs and outputs of the SUT is not only time-consuming but can also be error-prone.

What your Vector solution looks like:

Make use of the openness of CANoe and integrate it into a group of various run-time environments into a co-simulation. The VT System ensures that events for the stimulation of inputs and outputs of the SUT as well as network  events are synchronized. The VT System modules are specifically developed for the ECU test – a special signal conditioning is therefore not necessary.
