CANoe is the comprehensive software tool for development, test and analysis. Using CANoe, you can create simulations of entire networks or the remaining bus:

CANoe – Simulation of Entire Networks or Remaining Bus

Introduction

Usage of a single CANoe model in all phases of development

CANoe models can be distributed by the OEM or created on the supplier side

Function development and regression testing is supported

Gateway simulation for different bus systems is possible

One of the primary use cases of CANoe is to test ECUs and networks. These tests are used to verify individual development steps, test prototypes or to perform regression and conformance tests. CANoe services the System Under Test at all interfaces. This assures the fullest possible test coverage.

The Test Feature Set in CANoe consists of the following components:

Test Modules/Test Units

Constraints and Conditions

Collection of test functions

(Test Service Library)

Automatic report generation

Direct control of I/O hardware
