Simulation method for automotive electronic equipment immunity testing

Since safety is critical for automotive electronics devices, severe immunity tests are applied, then automotive component suppliers have to spend time in design and testing. Using simulation is one of key to realize effective design and testing, however, conventional simulation techniques do not enable the designer to predict malfunction frequencies despite that they are important for devising solutions. This paper proposes a simulation technique for predicting malfunction frequencies, noticing the transmission level of applied noise. Using this technique, we verified that simulation results well agreed with measurement results for frequencies up to 200 MHz.
