Will Cable Harness EMI Risk Autonomous Vehicle Safety?

As vehicles become progressively autonomous and more safety-critical functions are electrified, product engineers are counting on simulation to address electromagnetic interference (EMI) and electromagnetic compatibility (EMC) of large, interconnected electronic systems. That includes the cable harnesses that are crucial for transmitting electrical power and control signals to the electronics within cars, ships and aircraft.

Until now, though, there’s been no easy way to accurately simulate the interaction of cables, antennas, printed circuit boards and other subsystem components on a real platform. Instead, engineers were spending months, and sometimes even years, building full platform models from scratch, without guaranteed accuracy.

All that has changed with a datalink that integrates two leading electromagnetic simulation tools: Ansys EMC Plus and Ansys HFSS.

The datalink between HFSS and EMA3D Cable enables accurate, complex cable modeling
