Computer aided sneak circuit analysis on `As Built' wiring data

摘要

Conventional SNeak Circuit Analysis (SCA) method pays much attention and expenditure to generation of unctional network trees. Because of the huge amount of physical wiring data at late design cycle, i.e. the "as built" data, effective computer a ided analysis program is highly demanded. We developed our Computer Aided Network Tree Generation System (CANTGS) based on commercially available database softare. The system is designed to handle input of varous kinds of wiring data, data validity check and reduction, compoent modeling, connectivity database construction, path tracing, and to give out functional network trees for futhrer analysis. The corresponding overall SCA scheme, as well as technical aspects of every stage of data processing, are presented in this paper. Illustrative results on a tailored launch vehicle control system are also included.
