Abstract:
Method and system generally relating to integrated circuits are disclosed. In such a method, a secure lockdown mode for the integrated circuit is initiated. System states of a system internal to the integrated circuit are obtained after initiation of the secure lockdown mode. This obtaining of the system states includes: reading out of the system states from storage devices internal to the integrated circuit; and loading the system states into temporary storage of the integrated circuit. The system states are output via a port of the integrated circuit before closing the port responsive to the secure lockdown mode.
