CLASS

uvm_link_base

The uvm_link_base class presents a simple API for defining a link between any two objects.

Using extensions of this class, a uvm_tr_database can determine the type of links being passed, without relying on "magic" string names.

For example: |

 virtual function void do_establish_link(uvm_link_base link);
   uvm_parent_child_link pc_link;
   uvm_cause_effect_link ce_link;

   if ($cast(pc_link, link)) begin
      // Record the parent-child relationship
   end
   else if ($cast(ce_link, link)) begin
      // Record the cause-effect relationship
   end
   else begin
      // Unsupported relationship!
   end
 endfunction : do_establish_link
