A kind of approach based on signal model for resource configuration in ATE
-
摘要: 讨论了一种基于面向对象的信号模型构造方法在自动测试系统(ATE)测试环节中的应用,以解决测试资源有限和配置自动化的问题,并给出了一种由所需信号自动获取其资源信息的实现方法.通过分析测试资源与生成信号之间的关系,提出了由已知信号逐步递推获取资源信息的方法,并从理论上探讨了该方法的实现过程.提出了以生成信号的仪器资源信息和继承优先级为指标,从生成成本和生成层次上考察建立信号通道的思路.Abstract: Aiming to alleviate the limited test resource situation and provide an automatic configuration process, a signal modeling method based on object-oriented analysis was proposed with a general description language, and according to this consideration, an implementation approach that can acquire resource related information from a given signal was discussed. On the base of the possible relations between resources and signals, the recurrence expressions were presented, and the signal's resource condition and inherit priority were put forward to evaluate the cost and feasibility for the signal's generation and configuration.
