Abstract
An integrated circuit testing device, such as an ATE, configured with an architecture comprising a distinct software layer and a distinct hardware layer with an interface for tester abstraction providing a communication conduit between the software layer and the hardware layer. The software layer communicates in device under test terms whereas the hardware layer communicates in the terms of the testing apparatus. Various communication interface points are provided to the software and hardware layers, as well as the interface for tester abstraction.
Claims8
An automatic testing equipment comprising:
- a runtime software layer comprising indications of integrated circuit device under test pin information, the runtime software layer communicating in device under test terms;
- a runtime hardware layer comprising indications of integrated circuit automatic test equipment instrument information, the runtime hardware layer communicating in automatic test equipment hardware terms;
- and
- an interface for translating the device under test terms from the runtime software layer to the automatic test equipment hardware terms of the runtime hardware layer.
