Software development

What are the advantages of the multi-layer software development in PRUFREX control devices?
  • The multi-layer system architecture of PRUFREX control devices (hardware driver, firmware and application layer) allows different types of collaboration between PRUFREX and our clients.
  • One form is complete software development on the part of PRUFREX. Using a specification, the scope is determined and fully realised at PRUFREX.
  • Another option is for the customer to develop the application layer themselves. This is made possible using our model-based software development with a corresponding toolchain. The customer receives the control device with a basic application that can be adapted and extended. This software is then integrated by PRUFREX and the control devices delivered with it installed.
  • Finally, software development can also be completely taken over by the customer. PRUFREX’s role here is as the supplier of the hardware platform, while the software development is wholly in the hands of the customer. In this case, PRUFREX offers support and training.
  • Transitions can also be made smoothly between these development models.
What tools are used in software development?
  • Software development takes place in C and in model-based form with Matlab / Simulink.

  • To quality-assess the program codes generated, we use analysis tools such as MISRA-C Checker.

  • We also use automotive toolchains such as CANape and ETAS/Inca.

Quality in supplier management

How can counterfeits be detected using proper Supply Chain Management?

Through our established contact with manufacturers, purchases from third-party sources can be guaranteed by the manufacturer. On top of this, our development department always inspects purchases. This includes, for example, comparative measurements and X-rays of the chip structure. This ensures that only original components enter into customer projects.
