The trend of high frequency and high speed has brought many new problems to the Automotive Electronic circuit Hardware Reverse Engineer, among which the problem of electromagnetic compatibility is the most prominent.

The overall layout of the PCB board, chip selection, circuit wiring diagram, distribution of vias and through holes, ground wire design, the influence of various connectors, anti-interference design, filter design, and ground loop design are everywhere electromagnetic compatibility problem.
Due to the lack of high-speed analysis and simulation guidance in traditional PCB design, the signal quality cannot be guaranteed, and most of the problems cannot be discovered until the board is tested. This greatly reduces the efficiency of the design and increases the cost, which is obviously disadvantageous in the fierce market competition.

Therefore, for high-speed PCB design reverse engineer, a new design idea is proposed-a “top-down” design method, which requires the use of software to simulate and predict the electromagnetic compatibility of the designed system.
Aiming at the problem of electromagnetic disturbance in an automobile window electronic switch system after electromagnetic compatibility testing, this paper proposes to use the existing simulation software to simulate and analyze its PCB board diagram, and finally finds optimization measures to improve, which greatly shortens the product development cycle.
