CANoe is a development and testing software tool from Vector Informatik GmbH. The software is primarily used by automotive manufacturers and electronic control unit (ECU) suppliers for development, analysis, simulation, testing, diagnostics and start-up of ECU networks and individual ECUs. Its widespread use and large number of supported vehicle bus systems makes it especially well suited for ECU development in conventional vehicles, as well as hybrid vehicles and electric vehicles. The simulation and testing facilities in CANoe are performed with CAPL, a programming language.
In 1996 the first CANoe license was sold by Vector. Since then, the software has become established worldwide as a tool for ECU development. In addition to its primary use in automotive in-vehicle electronic networking, CANoe is also used in industries such as heavy trucks, rail transportation, special purpose vehicles, avionics, medical technology and many more.
New technologies based on IP architectures in the automotive industry[8] are supported by CANoe.[9] Beyond the scope of communication in a single car, CANoe is used in the development of cooperative systems via V2X.[10][11]
At the beginning of the development process for an ECU or ECU, CANoe is used to create simulation models that simulate the behavior of the ECUs. Throughout the further course of ECU development, these models serve as a base for analysis, testing and integration of the bus systems and ECUs.
Data is displayed and evaluated in either raw or symbolic format. Back in 1992, Vector developed the DBC data format, which has become a de facto standard for exchanging CAN descriptions in the automotive field. Other relevant standards are supported for other bus systems, e.g. FIBEX for FlexRay, LDF for LIN, Fibex for SOME/IP, EDS/DCF/XDD for CANopen.[5]
While CANoe can simulate the whole communication in a vehicle, it also includes a Test Feature Set, for creating automated test sequences. These automated test sequences can be controlled fully automated by usual CI tools (such as Jenkins etc). The Test Feature Set included in CANoe has a long history and is therefore available in variants; creation of test cases can be created in CAPL (Communication Access Programming Language - a C-like programming language), in XML, or in C#. The tests can either be manually programmed or generated automatically by different generators.
CANoe's Ethernet option includes Ethernet Conformance Tests (TC8 test suite).
CANoe's LIN option includes LIN Conformance slave tests.
Versions
Version 1.0 was released in 1996.[12] The latest version of CANoe is 18.[3]
Program Levels
Different variants of CANoe are available. They differ in functional scope (pro, run, pex), supported bus systems (CAN, FlexRay, etc.) and supported higher protocols (SAE J1939, CANopen, etc.).
The product supports the languages German, English and Japanese.
