Voltage spike detector and system for detecting voltage spikes in semiconductor devices

A system comprising:

• a voltage spike detector to:
• detect a voltage spike in a first analog signal received from a semiconductor device;
• and
• convert the first analog signal to a digital signal, including:
• generating a first pulse corresponding to the voltage spike;
• and
• transforming the first pulse into a stretched pulse having a desired width.

An apparatus comprising:

• an analog front end to:
• detect one or more voltage spikes in an analog signal, wherein the analog signal is obtained from a semiconductor device over a duration of a test program performing a test on the semiconductor device;
• and
• convert the analog signal to a digital signal with one or more first pulses representing the one or more voltage spikes, respectively;
• and
• a controller coupled to the analog front end, the controller to:
• generate location information of the one or more first pulses in the digital signal, wherein the location information is to include a first array of time stamps, the time stamps in the first array of time stamps corresponding to one or more stretched pulses in the digital signal.
