| // Title: UVMC Connection Example - SV to SC, SV side |
| // |
| // This example shows an SV producer driving an SC consumer via a TLM connection |
| // made with UVMC. |
| // See <UVMC Connection Example - SV to SC, SC side> to see the SC portion |
| // of the example. |
| // |
| // (see UVMC_Connections_SV2SC.png) |
| // |
| // Note: This example is derived from the UVM Connect examples, so the diagram |
| // depicts components with TLM2 sockets. TLM2 is not available in OVM, so this OVM |
| // components use TLM1 blocking put ports. Whether sockets or ports/exports, the |
| // connection syntax is the same. |
| // |
| // The ~sv_main~ top-level module below creates and starts the SV portion of this |
| // example. It does the following: |
| // |
| // - Creates an instance of a ~producer~ component |
| // |
| // - Registers the producer's ~out~ socket with UVMC using the string "foo". |
| // During elaboration, UVMC will connect this port with a port registered with |
| // the same lookup string. In this example, the match will occur with the |
| // consumer's ~in~ port on the SC side. |
| // |
| // - Calls ~run_test~ to start UVM simulation |
| // |
| // TLM connections would normally be made in the ~connect~ callback of |
| // a UVM component. This example does not show that for sake of highlighting |
| // the UVMC connect functionality. |
