Analysis Port in OVM :

Simple Fifo Example :

// Produce Class 
class producer extends verif_component;
    tlm_put_if #( int ) put_port;
    task run();
        for( int i = 0; i < 10; i++ )
        begin
        $display("about to put %d",i);
        put_port.put( i );
        end
    endtask;
endclass

// Consumer Class
class consumer extends verif_component;
    tlm_get_if #( int ) get_port;

    task run();
        int i;
        forever
        begin
        get_port.get( i );
        $display( "Just got %d" , i );
        end
    endtask
endclass

class producer extends verif_component;
    tlm_put_if #( int ) put_port;
    task run();
        for( int i = 0; i < 10; i++ )
        begin
             $display("about to put %d",i);
             put_port.put( i );
        end
    endtask;
endclass

class consumer extends verif_component;
  tlm_get_if #( int ) get_port;
   task run();
      int i;
     forever begin
       get_port.get( i );
        $display( "Just got %d" , i );
     end
  endtask
endclass

// Environement Class
class env;
   producer p = new;
   consumer c = new;
   tlm_fifo #( int ) f = new;
   function void connect;
                // Connect Port and Export
      p.put_port = f.blocking_put_export;
      c.get_port = f.blocking_get_export;
   endfunction
endclass

// Top Level Program
program top;
env = new();
       initial begin
         env.connect();
   verif_component::run_all_threads();
   end
endprogram
