UUT and model data for multiple test-techniques

Techniques for constructing a single description of the unit under test (UUT) for use with multiple test methods are proposed. They conclude a consistent user interface, a set of library and model tools, and a coherent set of data structures. The board and library software provide: an interface for use in bulk loading of board data; interactive software tools to allow modification and correction of the board and device descriptions; mechanisms for test preparation tools to be used to select data from the library; and facilities to allow the user to create special versions of models for use in the preparation and running of test data for a single board
