How can we add some approximate times to a TLM model..
We can get other approximate figures, such as bus utilisation and even perhaps power consumption using extensions to these techniques... Approximately-timed
Supported directly by the non-blocking transport interface.
Appropriate for architectural exploration and performance analysis.
Processes typically need to run in lockstep with SystemC simulation time.
Delays annotated onto process interactions are implemented using wait calls.
Multiple transaction phases with timing points.
Four phases of the base protocol, namely BEGIN_REQ, END_REQ, BEGIN_RESP, and END_RESP.
Uses a backward path (see additional material).
