Abstract
An apparatus and method is provided for switching input pins to scan channels to increase test coverage. In one embodiment, a scan system connects a small number of input pins to several scan channels so that the input pins may be selectively switched. The input pins may transmit independent test vectors to test a large number of test areas on a semiconductor chip. The scan system may include a switching device such as a multiplexer (MUX).
