Mitsubishi Electric Corp. has developed a new methodology to improve testing for electromagnetic compatibility (EMC) of its DIATONE automotive navigation/audio systems using NI AWR Design Environment, specifically Microwave Office circuit design software and AXIEM 3D electromagnetic (EM) simulation. The new flow has improved the sound quality of the DIATONE systems while decreasing overall analysis times by a factor of 10 and reducing design costs by more than 50 percent.

“Thanks to NI AWR Design Environment's ability to perform circuit simulation and EM analysis in one environment and to easily modify the circuit layout to identify the source of the noise, we were able to quickly improve the sound quality of our automotive navigation system while at the same time cutting development costs in half,” said Hajime Koyama, Manager, Design-C Section, Car Multimedia Manufacturing-B Dept. of Mitsubishi Electric.
