近年來(lái)出現(xiàn)的離散事件系統(tǒng)（DES）理論為數(shù)模混合電路的測(cè)試提供了一種新的解
決思路，本文對(duì)DES 理論在求取數(shù)?；旌想娐返目蓽y(cè)試性和最小測(cè)試集中的應(yīng)用進(jìn)行了論述。該種方法可以在計(jì)算機(jī)上用C++語(yǔ)言實(shí)現(xiàn)。
關(guān)鍵詞：數(shù)模混合電路，離散事件系統(tǒng)，可測(cè)試性，最小測(cè)試集,故障覆蓋率。
The research of the testability of Mixed-signal circuits based on the DES theory
ZHANG Qibo, LU Changhua, JIANG Weiwei (Hefei University of Technology, Hefei 230009) Abstract：The discrete event system theory that is developed in the recent years gave a new method for the mixed-signal circuits testing. This paper illustrates the application of the DES in the getting of testability and the minimum test set of the mixed-signal circuits. This method can be realized on computer by the C++.
Keywords: the Mixed-signal circuits ,the Discrete event system theory ,the Testability ,the Minimum test set ,the Fault efficiency.
