Functional Test

A functional test—also called electro-emulation test—is often done for pre-assembled components before their final installation.

The functional test simulates/emulates the real environment and forces switching operations that could otherwise only be done after installation. Voltages, currents and other measurement values are programmed and switching sequences are run in the exact same way, as it would happen in reality.

A test step—programmed in the editor and translated by the compiler—contains commands that change the conditions inside of the unit under test (UUT) during the test. The interconnection of the necessary voltages happens through test point cards, power cards or remote interfaces.

Afterwards an electrical test verifies and measures the effects of the switching operation. Step by step the test systems validates the accurate interaction of the components and if timing and performance are correct.

Testing options:


  •     Display and control units
  •     Central electronics of vehicles
  •     Dashboards
  •     Switching cabinets
  •     Complete vehicles
  •     Home appliances

In case a manufacturer owns an ISO 9001 certification, results are logged per unit under test (UUT) and forwarded into a database for further analysation in statistics or for retracing issues.
