Abstract:
Electronic devices, such as IC devices, are tested by determining a failure net within the electronic device that is causing a device failure. After identifying the failure net, the failure net is locally stressed. The stress is applied so that only the net being tested is subjected to the stress, and the remaining nets and components of the device are not stressed. A change in a signal produced by the failure net is observed while the failure net is being subjected to the stress. Testing in this manner assists in identifying the failure net as a failure source of the device.
