Functional testing & simulation

Realistic validation of your device intelligence

Ensuring flawless device functionality requires test systems that replicate the interaction of sensors, actuators and logic under real-world conditions. We develop customized functional test benches that precisely simulate complex operating states and fully verify every interaction of your product.

In modern product development, a simple “pass/fail check” is no longer sufficient. A functional test bench from WSK Elektronik simulates the entire operating environment of your product. Whether it involves communication via complex bus systems or the mechanical actuation of control elements: We build systems that test your hardware and software as a functional unit and ensure that your innovations respond exactly as they should in every situation.

Precise verification for complex system interactions

During prototype validation and series release, functional testing is the decisive quality gate. Insufficient test coverage can lead to costly software updates or field complaints that may jeopardize trust in your brand. WSK Elektronik understands functional testing as a combination of maximum testing depth and efficient test automation

We build systems that simulate physical input signals and use intelligent feedback to ensure that the internal control algorithms operate flawlessly. This creates a reliable basis for your product liability and compliance with functional safety standards.

Mapping complex usage scenarios and environmental conditions

To secure market readiness, all conceivable operating states must be tested reproducibly. Our test benches use state-of-the-art simulation technologies to bring the real world into the test field:

  • Sensor & actuator simulation: Generation of precise analog and digital input signals to simulate temperature sensors, pressure sensors or speed sensors, while simultaneously simulating the load of the actuator outputs.
  • Communication validation: Complete integration and verification of bus communication, such as CAN, LIN or Ethernet, to seamlessly monitor data exchange between your product and higher-level systems.
  • Haptics & interaction tests: Use of specialized robotics or linear technology to simulate human operation – from precisely defined button presses to the haptic feedback of rotary controls.

Deterministic measurement data acquisition and system integrity

The most critical risk in complex functional tests is non-deterministic timing behavior or incorrect signal interpretation. We address these challenges with a high-performance architecture:

  • Real-time monitoring: The system operates with deterministic cycle times to reliably detect time-critical processes and communication timeouts of your device under test.
  • Precision signal conditioning: Use of hardware with extremely high common-mode rejection and low noise to cleanly isolate even the smallest signal responses in industrially disturbed environments.
  • The WSK software framework: The entire control and test logic is based on a modular software architecture. By using LabVIEW, TwinCAT and high-level languages such as C# / C++, even complex test sequences can be implemented in a stable, high-performance way and precisely tailored to the respective testing task.

Your path to a customized functional test system

The development of a system for functional testing and simulation is an investment in the reliability of your control logic. To ensure that this investment delivers 100% test coverage, we combine our mechatronic expertise with systematic process planning. Within our proven 6-step process proven 6-step process, we place particular emphasis on three critical pillars in simulation projects:

1. Modeling the test environment

We support you in translating the physical boundary conditions of your product into precise simulation parameters in order to create a realistic hardware-in-the-loop (HiL) environment.

2. Development of the interaction logic

We implement the complete integration of all necessary communication protocols and physical interfaces for bidirectional data exchange.

3. Automation of fault analysis

We implement algorithms that immediately detect deviations in system behavior and store high-resolution snapshots of all signal states for fault diagnosis during development.

Planning reliability through validated functional processes

A functional test bench from WSK Elektronik is far more than a measuring device – it is the safeguard for your digital device intelligence. 

By combining robust mechatronics with intelligent software simulation, we minimize the risk of undetected logic errors and software bugs. We support you from the initial interface definition through to final integration into your quality assurance processes. Rely on testing technology that is just as smart as your products. 

Let us work together to safeguard the functional reliability of your innovations. Contact us for an initial technical consultation.

Frequently asked questions about our functional testing and simulation systems

Yes. Our software framework is open to the integration of external models. We support you in transferring your theoretical simulations into a real hardware-in-the-loop environment in order to test your prototypes against real physical loads.

We design according to the principle of “software agility”. Through the graphical interface of our WSK framework, you can independently adjust test steps, limit values and simulation parameters. New variants can be integrated without downtime using modular adapter kits and configurable software profiles.

Absolutely. Behavior in the event of faults is an essential part of functional validation. We integrate automated fault simulation modules that deliberately generate line interruptions, short circuits or corrupted bus data in order to verify the robustness of your safety algorithms.

We use high-precision DAC modules (digital-to-analog converters) and signal generators that are regularly calibrated automatically. Through a readback function, the system continuously monitors whether the simulated signal actually reaches the device under test within the specified tolerance.
