Abstract
In an automated test equipment system for testing a circuit board containing a plurality of interconnected digital devices, an in-circuit test is created for a device under test based on stimuli used to test devices which drive the device under test. The method includes the steps of determining, from the electrical interconnect data for the devices on the circuit board, which devices have an output driving an input of the device under test; testing each of the driving devices; observing the response of the device under test during testing of the driving devices; and using the test stimuli for the driving devices and the observed response of the device under test as an in-circuit test for the device under test.
