| // Title: Another SV Consumer |
| // |
| // Topic: Description |
| // |
| // A simple SV consumer TLM model that prints received transactions (of type |
| // ~uvm_tlm_generic_payload~ and sends them out its ~ap~ analysis port. |
| // |
| // The ~in~ member exports the ~tlm_blocking_transport_if~ interface, which |
| // is called via a model whose port is connected to the export. |
| // |
| // Instead of an export, a blocking target socket could have been used. To do |
| // this, comment-out the current declaration for ~in~ and uncomment the socket |
| // declaration. Any port connected to this component must now be compatible |
| // with the blocking target socket. |
| // |
| // 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 imp 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. |
