The stimulus and analysis requirements of system ing multiple functions at the same time. The systems will need to automatically reconfigure themselves depending on the stimulus at one or more of their sensor ports. So, a benign or static test stimulus that may be sufficient to level testing differs from the functional testing verify a lower level subsystem will not be suf- of the various sub-systems, boards and compo- ficient to fully exercise the dynamic operation nents that make up the system for a number of the full system under all or even a few of its of reasons. For instance, these types of sys- operating conditions. tems are becoming increasingly multi-role and To provide an environment adequate for multi-mode in nature, perhaps even perform- functional evaluation of the system, the test stimulus must be long and unique
