// Title: TLM Implementation Port Declaration Macros
25 
//
26 
// The TLM implementation declaration macros provide a way for components
27 
// to provide multiple implementation ports of the same implementation
28 
// interface. When an implementation port is defined using the built-in
29 
// set of imps, there must be exactly one implementation of the interface.
30 
//
31 
// For example, if a component needs to provide a put implementation then
32 
// it would have an implementation port defined like:
33 
//
34 
//| class mycomp extends uvm_component;
35 
//|   uvm_put_imp#(data_type, mycomp) put_imp;
36 
//|   ...
37 
//|   virtual task put (data_type t);
38 
//|     ...
39 
//|   endtask
40 
//| endclass
41 
//
42 
// There are times, however, when you need more than one implementation
43 
// for an interface. This set of declarations allow you to easily create
44 
// a new implementation class to allow for multiple implementations. Although
45 
// the new implementation class is a different class, it can be bound to
46 
// the same types of exports and ports as the original class. Extending
47 
// the put example above, let's say that mycomp needs to provide two put
48 
// implementation ports. In that case, you would do something like:
49 
//
50 
//| //Define two new put interfaces which are compatible with uvm_put_ports
51 
//| //and uvm_put_exports.
52 
//|
53 
//| `uvm_put_imp_decl(_1)
54 
//| `uvm_put_imp_decl(_2)
55 
//|
56 
//| class my_put_imp#(type T=int) extends uvm_component;
57 
//|    uvm_put_imp_1#(T,my_put_imp#(T)) put_imp1;
58 
//|    uvm_put_imp_2#(T,my_put_imp#(T)) put_imp2;
59 
//|    ...
60 
//|    function void put_1 (input T t);
61 
//|      //puts coming into put_imp1
62 
//|      ...
63 
//|    endfunction
64 
//|    function void put_2(input T t);
65 
//|      //puts coming into put_imp2
66 
//|      ...
67 
//|    endfunction
68 
//| endclass
69 
//
70 
// The important thing to note is that each `uvm__imp_decl creates a
71 
// new class of type uvm__imp, where suffix is the input
72 
// argument to the macro. For this reason, you will typically want to put
73 
// these macros in a separate package to avoid collisions and to allow
74 
// sharing of the definitions.
