Description

Interfaces Implemented

Notifiers

cell-change

Notifier that is triggered after the object's cell was changed.

object-delete

Notifier that is triggered just before Simics object is deleted.

queue-change

Notifier that is triggered after the object's clock was changed. New clock can be obtained with the SIM_object_clock function.

Commands for this class

• info – print information about the object

• print-statistics – print statistics
• status – print status of the object

Commands for interface table

policy

Optional attribute; read/write access; type: s
