The system watchdog timer (SWDT) helps to maintain a healthy and secure system by detecting errant software, deadlock conditions, tampering, and unexpected behavior.

The AMD Versal™ adaptive SoC SWDT includes a generic watchdog timer based on the MPSoC SWDT with the addition of a windowed environment mode that is derived from an AMD LogiCORE™ IP. The windowed mode also adds a Q&A token response handshake. The following table lists the SWDT implementations.
