Abstract:
Tolerance design, including toleranc e analysis and distribution, is an important part of the electronic system’s reli-ability design. The traditional design needs to construct mathema tic model of material circuit, which involves large amount of workload and lacks of practicability. This paper discusses the basic theory of electronic system’s reliability tolerance design and presents a new design method based on EDA (Electronic Design Automatic) software. This method has been validated through the
application research on reliability tolerance design of the DC hybrid contactor’s control circuit.

Key words: Reliability, Tolerance analysis, EDA (Electronic Design Automatic)

摘要：容錯設(shè)計，包括容錯分析與分配，是電子系統(tǒng)的穩(wěn)定性設(shè)計中一個重要的組成部分。在傳統(tǒng)的設(shè)計過程中需要對物理線路建立數(shù)學模型，這其中包含了巨大的工作量并且缺乏實用性。在該篇論文中，將討論電子系統(tǒng)的穩(wěn)定性容錯設(shè)計并且提出一種基于EDA（電子設(shè)計自動化）軟件的新方法。該方法已經(jīng)在直流混合開關(guān)控制電路的穩(wěn)定性容錯設(shè)計的應(yīng)用研究中得以驗證通過。
