Multi-master AXI interface connections

Question

Do we need to have three instantiations of AXI master interface in top file if we have 3 AXI masters and then send these three interfaces to 3 AXI agent instantiations using the config_db? Or, how does it work in case of a multi-master scenario to make connections of interface with the DUT?

Answer 1

Yes, to fully verify your DUT, you need one interface in your testbench for each DUT interface. Since your DUT has 3 AXI interfaces, you need 3 AXI interface instances in the testbench, and you add all 3 of them to the uvm_config_db to be passed to each AXI agent.
