Uvmkit_register_bind_intf_vif and uvmkit_register_bind_intf_vif_inst

I am trying to bind interface to RTL module but I am not sure which one should I use to register it in UVM ?
one is uvmkit_register_bind_intf_vif
and the other is uvmkit_register_bind_intf_vif_inst

Here is a snippet code for this. In RTL side, we have a module defined as shown below.
RTL code :


module rs ( clk, rstb, valid, data );
...
endmodule

And there would be 4 instances for this module inside DUT (tb)
Here is top tb file :


module tb;
.....
  rs rs0 (.clk(tb_clk), .rstb(tb_rstb), ....);
  rs rs1 (.clk(tb_clk), .rstb(tb_rstb), ....);
  rs rs2 (.clk(tb_clk), .rstb(tb_rstb), ....);
  rs rs3 (.clk(tb_clk), .rstb(tb_rstb), ....);
.....
endmodule : tb

interface code :


interface my_intf ( input clk, input rstb, inout valid, inout[31:0] data);
      clocking master_cb @(posedge clk);
           input rstb;
           output valid;
           output data;
    endclocking : master_cb
......
endinterface

bind code : (how to use uvmkit_register_bind_intf* to register these bind codes into UVM resource database ? )


bind rs:rs0 my_intf  my_intf_inst0 (...)
bind rs:rs1 my_intf  my_intf_inst1 (...)
bind rs:rs2 my_intf  my_intf_inst2 (...)
bind rs:rs3 my_intf  my_intf_inst3 (...)

In reply to zz8318:

You are referring to code/macros that are not part of the UVM standard. You should read the documentation that comes with your library for additional information.

In the local library, here is what I found.


// This macro deposits the virtual interface referencing the interface 
// variable into the resource database provided by <uvm_pkg>, 
// under the "uvmkit_interface_registry" scope.
// In effect, this is done:
// |uvm_pkg::uvm_resource_db#( virtual IF_TYPE )::set("uvmkit_interface_registry",
// |                                                            <interface path>,
// |                                                            <interface instance>);
// Note:  This macro should be used when using the bind technique to instance the interface.

But I am not sure how to bind the interface to 4 instances separately ? It looks like we only can bind an interface to a RTL module ?
