The surge of electronic systems in modern vehicles mandates a careful examination of Electromagnetic Interference (EMI) and Compatibility (EMC) issues. With an increasing number of components, including advanced driver assistance systems, concerns such as cross talk, radiation, and interference arise, posing threats to reliable system operation. Addressing these issues early in the design phase is crucial. Electromagnetic simulation plays a crucial role in EMI/EMC analysis by identifying and resolving problems through software simulations, minimizing the need for costly modifications later on. This approach enables optimized system layouts, strategic shielding, and precise component placement, ensuring enhanced electromagnetic compatibility in the evolving modern vehicle electronics.
