隨著高頻通訊時代的來臨，全球各國紛紛提高對電磁干擾與電磁相容性的要求。在電子產品設計中，可以用接地、電磁屏蔽、濾波三種方式來降低電磁干擾及完成電磁相容設計。但最根本的解決方式則是減少電磁輻射產生的機率。高頻率clock的運作是電子系統中產生電磁輻射的主要來源，採用非同步電路設計能夠有效的減少電磁輻射產生的途徑。本研究主旨在於將System描述合成為同步與非同步混合設計電路。透過將SystemC軟體描述部分轉換成非同步電路與原本硬體同步電路部份進行結合。包含同步電路、非同步電路及同步到非同步的溝通介面，藉由此架構來達成低耗電極低電磁干擾電路的實作。

Because the age of high frequency communication comes, every country over the world increases the demand for electro-magnetic interference (EMI) and electro-magnetic compatibility (EMC). Ground connection, electromagnetic screen and filter can be used to reduce EMI and to achieve the design of EMC in electronic products. But the fundamental way is to decrease the generating of electro-magnetic radiation. The high frequency clock generation is the major source of electro-magnetic radiation in electronic products and this can be avoided by exploiting asynchronous circuits to decrease electro-magnetic radiation generation. The purpose of this thesis is to propose a methodology to automatically synthesize SystemC description to mixed-design circuits containing synchronous circuit, asynchronous circuit and their interface for low power and low EMI design.
