Abstract: With the production of many plug-in hybrid electric vehicles and electric vehicles, the degree of integration is increasing for electronic components used in steering, braking, suspension, infotainment, BMS and instrument panel systems. Consequently, the possibility of malfunction due to the mutual interference of electromagnetic waves generated from the systems has increased, and the system design should consider resistance to electromagnetic wave generation and interference based on the electromagnetic wave standards. Power integrity refers to the stabilization of power supply system in the PCB design process, and integrity signals can be composed by strengthening the power supply, which is vulnerable to noise. This allows us to predict, modify, and solve the structural problems of circuits before producing the PCB, thereby minimizing the redesign of PCB. As a result, we can shorten the development time, save the cost, and improve the reliability of electromagnetic waves for systems.
