基于用户规则的PCB板级后验证系统

PCB - board post verification system based on user - specifed rules

针对PCB仿真模型预购难求,PCB仿真难以实现的情况,本文提出并实现了一种基于用户规则的PCB板级后验证系统。本系统以芯片外围电路设计规则为主体建立器件规则库,在规则容易获取的同时用户的设计经验也得以继承。同时针对PCB图的特有复杂性,提出了一种合理而实用的分区算法,使验证工作正确、高效地完成。

According to the situation of scarcity of PCB simulation models, a PCB -board post verification system software based on the user - specifed rules was proposed and realized in this paper. Because the database for component - rules is based on the design - rules of the circuits around the ICs, the component - rules are conveniently achieved by users and the experience for design was well inherited. At the same time ,the blocking algorithm is presented and adopted here according to the complexity of the PCBs . The experiment results prove that the key algorithm are of practicality and high effectivity for the verification task.
