There are two system watchdog timers (SWDT) instances on the device, and both have the same programming model.

Table 1. System Watchdog Timers
SWDT Instance Name Description I/O Signal Prefix Alternate Name
LPD_SWDT For RPU SWDT0_ WWDT0
FPD_SWDT For APU SWDT1_ WWDT1

It is possible to implement an external watchdog timer (WDT) to monitor the health of other processors and controllers. This can be done in the PL or external to the device. See the Versal ACAP System Software Developers Guide (UG1304) for an example framework for the PLM firmware.
