【摘要】 针对通用测试系统对系统统一模型的迫切需求以及目前ATE(AutomaticTest Equipment)模型化设计的不足,基于信号建立了一套完整、有效的ATE系统模型.此模型将ATE系统的硬件资源以及UUT(Unit Under Test)均进行了模型化处理.提出了基于TFF(Test Foundation Framework)的基本信号模型;提出了完全基于信号的仪器驱动模型;提出了基于测试与诊断相结合思想的UUT模型;提出了基于模型间信息共享的思想和路径以逻辑开关描述思想的路径模型.该模型体系为系统资源配置、仪器可互换、测试程序自动生成以及故障诊断提供了强有力的模型基础,从而大大加快了ATE的设计过程,从很大程度上降低了开发成本.更多还原

【Abstract】 Aiming at the problems in the modeling design of general purpose automatic test equipment(ATE) and in order to satisfy the requirement of the model of ATE,a integrated ATE model was presented based on signal.The ATE hardware and unit under test(UUT) are both made models.A basal signal model was established based on test foundation framework(TFF).The device driver model based on signal was proposed.The UUT model was proposed based on the thought of integrating test and diagnosis.The route model was pointed out based on the thought of sharing information between models and the thought of describing route with logic switch.This model gave direction to the resource allocation,instrument’s interchangeability,the automatic generation of test program set(TPS) and fault diagnosis.So the use of the model can quicken the design process greatly and reduce the cost greatly.更多还原
