Abstract:
A system, method, and device to test an electronic circuit are disclosed having a stage to supply a driving signal to a load comprising a pull-up switch and a pull-down switch and a pre-driver stage including pre-driver circuits. The electronic circuit including circuits for testing the pre-driver stage under the control of an automatic testing equipment (ATE) to operate a built-in self-test sequence including test commands for the pre-driver stage under the control of an external test signal issued by the ATE. The system includes a time measuring circuit to measure duration of signals at the output of the stage coupled to a pass-fail check circuit, and to evaluate if the duration of signals at the output of the stage to determine whether the output satisfies a pass criterion.
