System Level Testing on complete systems is used to verify their functional specification and performance requirements. Such testing will find errors in the assemblies that make up the system or in the system as a whole. The test specification incorporates the expected customer usage pattern. System level testing gives best results when the individual components have also been tested at unit level. The testing identifies any issues due to the interaction of the multitude of components with each other as well with the environment and the user. This human factor aspect i.e. the effect of the envisaged user behaviour forms an important part of any system level test system.
Conventionally, custom built test jigs or manual processes are used for system testing with detailed manual work instructions for performing the system level testing. Some disadvantages of this approach are the strong dependence on operator skill, high time to test, & lower reliability. A System Level ATE (SLATE) will automate, supervise and augment the test process to boost the operator accuracy and speed of testing by replacing the test jig and manual controls by a computer controlled system with simplified easy to use interface with the DUT.
