LV 124 / LV 148 – THE CHALLENGES

  • INCREASED ECU COMPLEXITY

    ECU complexity is constantly increasing and therefore ECU testing is becoming more complex as well. The manual documentation effort is getting too high.

  • SHORT TESTING TIMES

    Testing times are getting shorter in order to meet time-to-market requirements, putting even more pressure on the testers.

  • AUTOMATED TESTING NEEDED

    Manual testing becomes obsolete as it cannot cover the complexity needs required by the norm, in the given time, with the needed reproducibility and documentation requirements.

KNOW-HOW

WHAT OUR CUSTOMERS SAY

Ralf Zimmermann

This innovative modular concept, which gives us the opportunity to monitor a high number of pins in parallel, with a high resolution of up to 10us, as required in the LV124, allows us to make a deeper analysis of our products and especially find sporadic errors earlier in the development phase.

Ralf ZimmermannTechnical Project LeadContinental™ AG
Thomas Richter

Because of RTStand we were able to detect a sporadic error we would not have found with the old approach. This saved us a lot of money, as the failure has been detected in a very early stage of development of our gateway.
