Abstract
Failing test pattern simulations are performed to determine initial defect suspects based on injecting faults to defect candidate sites which are derived based on test responses. Initial inter-cell bridge suspects are then determined from cells in the initial defect suspects based on layout information and electrical information of the circuit. Passing test pattern simulations are performed to determine inter-cell bridge suspects from the initial inter-cell bridge suspects.
