A watchdog circuit for monitoring a plurality of virtual machines provided by one core of a plurality of cores. The watchdog circuit may include a first memory portion, a second memory portion, and a control logic configured to count a number of pulses, to, when starting the watchdog circuit, store a global watchdog counter value in the first memory portion, and to store a local counter value for each virtual machine of the one or more virtual machines in the second memory portion, and, after a predefined number of pulses, to modify the global watchdog counter value and the local counter values, and, if the global watchdog counter value fulfills a predefined global watchdog reference criterion or any of the local watchdog counter values fulfills a predefined local watchdog reference criterion, to output an error signal.
