Abstract :
A simple circuit example is presented to demonstrate that the set of checkpoints should include the fan-out stems of primary inputs for irredundant combinational circuits. It is shown that transistor faults are not sufficient to constitute a complete set of checkpoints for combinational MOS circuits.
