Abstract:
1. A process of testing a functional circuit comprising: A. capturing response data bits from the functional circuit in scan cells of plural serial scan paths; B. shifting one of the captured response data bits out of and one stimulus data bit into one of the serial scan paths while disabling all the other serial scan paths from shifting while shifting one of the captured response data out of and one stimulus data bit into the one serial scan path in response to a mode input signal remaining in one state; and C. shifting one of the captured response data bits out of and one stimulus data bit into another one of the serial scan paths while disabling all the other serial scan paths from shifting while shifting one of the captured response data bits out of and one stimulus data bit into the another one serial scan path in response to the mode input signal changing state once and then remaining in the one state.
