Detailed Description

The traffic generator is a master module that generates stimuli for the memory system, based on a collection of simple generator behaviours that are either probabilistic or based on traces.

It can be used stand alone for creating test cases for interconnect and memory controllers, or function as a black box replacement for system components that are not yet modelled in detail, e.g. a video engine or baseband subsystem.

◆ drain()

DrainState BaseTrafficGen::drain ( )

overridevirtual

Notify an object that it needs to drain its state.

If the object does not need further simulation to drain internal buffers, it returns DrainState::Drained and automatically switches to the Drained state. If the object needs more simulation, it returns DrainState::Draining and automatically enters the Draining state. Other return values are invalid.

Note: An object that has entered the Drained state can be disturbed by other objects in the system and consequently stop being drained. These perturbations are not visible in the drain state. The simulator therefore repeats the draining process until all objects return DrainState::Drained on the first call to drain().

Returns: DrainState::Drained if the object is drained at this point in time, DrainState::Draining if it needs further simulation.

Implements Drainable.

◆ getPort()

Get a port with a given name and index.
