register a callback for a certain time point
This function allows to register a callback for certain time points of a transaction (see #axi::fsm::protocol_time_point_e). The callback will be invoked after the FSM-actions are executed.
e | the timepoint |
cb | the callback taking a reference to the transaction and a bool indicating a snoop if true |

triggers a non-blocking snoop response if the snoop callback does not do so.

overridevirtual |
The forward transport function. It behaves blocking and is re-entrant.
This function initiates the forward transport either using b_transport() if blocking=true or the nb_transport_* interface.
trans | the transaction to send |
blocking | execute in using the blocking interface |
