TRANSITION DELAY FAULT MODEL (TDF) (Contd...) In this case, the output of the AND gate is always going to be 0 (since B is tied to ground). Therefore transition can’t be created in Y net. As B net is tied to ground, transition can’t be created in B net. In A net, transition can be created but it can’t be propagated to an observation point (SFF3) [as B net is tied to ground, Y is always 0] Therefore, in this scenario, none of the TDF faults will get detected.
