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.
Keywords�� automatic testing   models   based-signal   device model   route model   UUT model
