clock-extension

Description

The clock-extension extension class is used to extend - see SIM_extend_class - CPU and clock classes with event posting functionality. The interfaces frequency and, for CPU classes, event_delta are to be provided by the class which is extended with this extension class.

The clock-extension class creates an instance of the vtime class - see vtime class - in the 'vtime' port of the parent object. The parent object should use the event_handler interface of the vtime object: event_handler's documentation describes the requirements to the parent object.
