Accurately Predict and Mitigate EMC/EMI in Automotive Systems

The SIMULIA electromagnetic portfolio helps catch EMI early — from a single component to the full vehicle.

Modern Vehicles Demand a New Approach to EMC/EMI

Electrified powertrains, high-density electronics and advanced communication systems are raising the stakes for electromagnetic compatibility (EMC). Managing electromagnetic interference (EMI) across these interdependent systems is no longer something physical testing alone can solve. Certain coupling paths don't appear until full vehicle integration. By then, a redesign is costly.

SIMULIA offers a comprehensive portfolio of electromagnetic (EM) simulation solutions, including CST Studio Suite® technology, available on the 3DEXPERIENCE® platform. It combines full-wave solvers in the time and frequency domains, a multiconductor transmission-line method, RLC extraction and hybrid solvers—all coupled to a powerful circuit simulator.

The result: engineers can predict, visualize and mitigate issues at every level, from individual components to the complete vehicle system.

EMC/EMI Challenges

Power Electronics

Interactions between high- and low-power components and surrounding subsystems generate EMI that's increasingly hard to manage in complex power systems.

High-Speed PCBs & Electronics

High-density PCB layouts and rising data rates in infotainment and ADAS systems make signal and power integrity issues difficult to catch through testing alone.

Vehicle-Level EMC Integration

As vehicle complexity grows, EMC compliance gets harder — and some coupling paths, like those over long cables, don't show up in lab testing until integration.

CoSite Interference Mitigation

Placing antennas close together increases the risk of mutual interference, threatening V2X system performance.

Thermal Management

High power density and variable operating conditions make thermal management of power electronics in electric vehicles especially demanding.
