Abstract:
1. A method of testing a device of the type that includes a plurality of pins with a system comprising a pulse generation circuit, a relay pin matrix, an oscilloscope, and a controller, wherein the pulse generation circuit is electrically coupled with the relay pin matrix, oscilloscope, and controller, and wherein the controller is electrically coupled with the relay pin matrix and oscilloscope, the method comprising: programmatically controlling the relay pin matrix with the controller to relay a signal from the pulse generation circuit to at least one pin from among the plurality of pins of the device; producing a triggering signal with the controller; transforming the triggering signal into a test signal and a ratio signal with the pulse generation circuit, wherein the test signal is operable to test at least one of a transient induced latch-up or an electrical overstress characteristic of the device, transforming the triggering signal into the test signal and the ratio signal further comprising: measuring the test signal and the ratio signal with the oscilloscope during the testing; in response to relaying the test signal to at least one pin of the device and measuring the ratio signal, determining at least one of the transient induced latch-up or electrical overstress characteristic of the device.
