    Abstract—A design challenge in automobile electronic system is the compliance to electromagnetic compatibility (EMC) requirements. Traditionally, EMC issues are not detected until a prototype has been built, it will require many procedures and time to rectify these issues. In this paper we present an EMC simulation process including board-level S-parameter extraction, transient analysis and near-field simulation. Finally, the simulation results are compared with measurement data.

    在車輛電子產品設計中,如何達到符合電磁相容性(EMC)的要求,是工程師所面臨的挑戰。在傳統的設計流程中,無法於設計階段確保產品的EMC特性,必須等到試作件完成後,才能進行相關的EMC特性檢測,但在此階若無法滿足相關標準的需求,則必須花上許多的時間進行產品改善,甚至可能在此階段無法提出有效的改善方案,而需要進行重新設計,但即便回歸重新設計的階段,依舊需要於試作件完成後,才確認是否有達到相關規範要求。為此本文提出一個EMC電腦模擬流程,期望於設計階段確認其產品相關EMC特性,其流程包括PCB板的S參數計算,電流擾動的模擬分析和近場模擬。且最後將模擬結果與量測數據進行比對。
