The "GLITCH" port is used for voltage glitching. It's connected to two MOSFET elements, as the following figure shows:

The CW1173 glitch output can be commanded to turn on either of those MOSFETs via scope.io.glitch_hp and scope.io.glitch_lp fields:

scope.io.glitch_hp = True #enable high power glitch
scope.io.glitch_hp = False #disable high power glitch

scope.io.glitch_lp = True #enable low power glitch
scope.io.glitch_lp = False #disable low power glitch

Be careful using this feature, as you don't want to short the MOSFETs for too long. It's also possible to damage the ChipWhisperer-Lite by burning these MOSFETs up if used incorrectly. See tutorial Fault_2 (https://chipwhisperer.readthedocs.io/en/latest/tutorials/fault_2-openadc-cwlitearm.html#tutorial-fault-2-openadc-cwlitearm) for more information.
