Develop and Test Software of Distributed Systems with CANoe4SW
CANoe4SW is the comprehensive tool for development, test, and analysis of software in cyber physical systems — individual software components as well as subsystems and entire distributed systems. CANoe4SW supports software developers and testers in all markets (medical, railway, automotive, …) throughout the entire development process of distributed systems and IoT devices. Virtual execution environments on the computer, in virtual machines, or in the cloud enable software to be tested for any targeted OS based on Windows or Linux, e.g., Ubuntu, CentOS, SUSE.
The System Under Test is accessed by its functional system interfaces at a pure software level. This enables early “black-box” SIL testing independently of hardware availability. CANoe4SW integrates seamlessly in CI/CT environments.
In addition, the support of connectivity protocols such as MQTT provides access to IoT devices and back end software running in the cloud.
- Interactively develop and test distributed systems
- Easily automate tests to ensure quality at a system-level
- Divide and conquer the system
by isolating single components using models for both physical and software environments
- Test early in the development process
by utilizing virtual execution environments
- Cover dynamic aspects of the software under test
by stimulating and monitoring value curves over time
- Simulate failure scenarios
not easy to be covered in real environments, e.g. downtime of cloud services
- Utilize CI/CT environments
right from the beginning by being independent of hardware and other software components
Monitoring over Time
Monitoring over time fully integrated software components: Run your software under test asynchronously in virtual execution environments. Observe dynamic aspects while stimulating the application via its functional system interfaces at a software level.
Environment simulation by models: Build a “natural ecosystem” for your software under test. Simulate both physical and software environments. Test single software components in isolation before integrating into subsystems.
Interactive Development and Test
Interactive development and test in an exploratory way: Stimulate the software under test using panels, waveform generators, and scripts. Analyze the reaction of your application and value relations via graphical and text-based analysis windows.
Automated testing with the test design tool vTESTstudio: Leverage the flexibility of various test design methods such as graphical diagrams and tabular sequences. Benefit from flexible parametrization concepts and universal variant support. Ensure traceability from requirements to test cases and results.
Debugging on the host: Profit from the power to debug in the development environment rather than on the target. Observe application behavior, view and modify internal variables, watch call stacks, etc. while stimulating the application via interactive or automated tests.
Highlights Version 15
- Python Support:
For SIL tests in virtual environments Python is now supported as programming language for the software under test; additionally application models can be realized in Python.
- Testing by OTA Protocols:
The new hardware VH4110 (IoT Enabler) enables easy access to connected devices by OTA (Over-the-Air) protocols like WLAN, Bluetooth, etc.
- Experimental Testing:
The „Application Panel“ allows easy interactive stimulation of application layer objects, e.g. to call a method of the system under test.
- Fast Access To MATLAB Models:
The new Model Viewer for MATLAB gives fast access to models described with MATLAB/Simulink.
- Coupling With 3rd-Party Tools:
The support of the XIL API standard allows coupling with 3rd-party tools.
Test of IoT Applications
Connectivity Features Service
The Connectivity Features Service allows you to easily connect your System Under Test (pure software or a real device) to a back end or local broker. MQTT is already supported, further protocols are planned.
For more details, see Connectivity Features Service for IoT
Interfaces to 3rd-Party Tools
CANoe4SW supports the integration of other tools via open interfaces and various well-established standards.
An interface to MATLAB/Simulink enables model in the loop tests as well as the simulation of MATLAB models. FMI (Functional Mock-up Interface) is as a tool-independent standard to exchange models or to establish tool couplings.
Open APIs allow 3rd-party tools to exchange simulation values with CANoe4SW and to control the overall simulation as well as the automated test execution.
The integration with various test management systems ensures traceability from requirements and test specifications to test cases and test results.
Platforms, Programming Languages, and Protocols
Any Windows or Linux based platform is supported. The software under test can be executed on the same PC as CANoe4SW, a virtual machine or a remote host. The supported programming languages are currently C, C++ and Python.
The MQTT protocol allows access to IoT devices and back end software running in the cloud. Support of further IoT protocols e.g. AMQP is planned.
Continuous Integration and Test
Automated tests with CANoe4SW can easily be integrated into continuous integration and test environments using CANoe4SW Server Edition. CANoe4SW Server Edition is the virtual runtime for simulating and testing in a server environment under Windows or Linux.
MIL, SIL, HIL
Seamless Integration Into the Development Process
System setups and tests created with CANoe4SW can seamlessly be re-used in CANoe for hardware/software integration tests and system validation. This allows a consistent development and testing tool chain for MIL, SIL and HIL. The feature set of CANoe4SW is also available to all CANoe users. For further details please refer to CANoe.
The seamless integration of CANoe4SW and VectorCAST/QA enables automatic measurement of code coverage during system level tests in virtual environments. Untested portions of the application can quickly be identified. Using this data VectorCAST/QA additionally identifies correlations between tests and code. As the code changes, it automatically computes the minimum set of tests required to provide complete testing of the change.
