Abstract
A method of testing a semiconductor device against electrostatic discharge includes operating the semiconductor device, and, while operating the semiconductor device, monitoring a functional performance of the semiconductor device. The monitoring includes monitoring one or more signal waveforms of respective one or more signals on respective one or more pins of the semiconductor device to obtain one or more monitor waveforms, and monitoring one or more register values of one or more registers of the semiconductor device to obtain one or more monitor register values as function of time. The method includes applying an electrostatic discharge event to the semiconductor device while monitoring the functional performance of the semiconductor device. The method can further comprise determining a functional change from the one or more monitor waveforms and the one or more monitor register values as function of time.
