Simulator
The standalone simulator features a set of trace players, traffic generators and miscellaneous components that can be coupled with DRAMSys.
Concept
Initiators in the simulator are split up into two disctinct components: RequestProducers and the RequestIssuer.
RequestProducers are simple C++ classes that implement the RequestProducer interface. Upon calling the nextRequest() method of a producer, a new Request is either generated on-the-fly or constructed from a trace file.
The RequestIssuer is the SystemC module that connect to DRAMSys. The Issuer has no knowledge of where the requests are coming from. It simply calls the nextRequest() method of its associated producer to obtain the next request to be sent to DRAMSys. Using this concept, the generation and the issuing of request is completely decoupled to make very flexible initiator designs possible.
Requests are an abstraction over the TLM payloads the issuer generates. A request describes whether it is a read or a write access or an internal Stop request that tells the initiator to terminate.
Configuration
