| // Title: SC Consumer |
| // |
| // Topic: Description |
| // |
| // A simple SC consumer TLM model that prints received transactions (of type |
| // ~tlm_generic_payload~ and sends them out its ~ap~ analysis port. |
| // |
| // This example uses the ~simple_target_socket~, a derivative of the TLM |
| // core class, ~tlm_target_socket~. Unlike the ~tlm_target_socket~, the simple |
| // socket does not require the module to inherit and implement all four |
| // target socket interface methods. Instead, you only need to register the |
| // interfaces you actually implement, ~b_transport~ in this case. This is what |
| // makes these sockets simple, flexible, and convenient. |
| // |
| // While trivial in functionality, the model demonstrates use of TLM ports |
| // to facilitate external communication. |
| // |
| // - Users of the model are not coupled to its internal implementation, using |
| // only the provided TLM port and socket to communicate. |
| // |
| // - The model itself does not refer to anything outside its encapsulated |
| // implementation. It does not know nor care about what might |
| // be driving its ~in~ socket or who might be listening on its ~ap~ |
| // analysis port. |
