ABSTRACT:
A method and circuitry for testing in situ the components mounted on a circuit board. First, a component is removed from the board. A testing circuit is then installed in place of the removed component. The testing circuit allows test patterns to be applied to a selected component on the board from the board I/O pins. The selected component responses are collected by the testing circuit and applied to the board output pins. In this manner, individual components on the board can be tested in situ from pins on the board.
