xplmi_glitch_detector_example.c File Reference

Overview

This file illustrates glitch detector usage To build this application, xilmailbox and xilpm libraries must be included in BSP and xilplmi library must be in client mode.

This example is supported for Versal and Versal Net devices.

Procedure to run the example.

Generate pdi with glitch_detection_overlay cdo. Load the Pdi. Select the target. Download the example elf into the target.

Procedure to test glitch on hardware

Refer versal plm wiki to configure the glitch detector

This code intends to provide an example to test the glitch detector functionality by generating the test glitch. User must disable that and have a programmable power supply for Vcc_PMC and generate the actual glitch by varying the power supply
