Monitor Sends an Item to Reference Model

1. Collecting an item - all overhead bytes of a frame - and sending this item to reference model, was the preferred method.

Pros

2. Low memory consumption during synchronized state.
3. Memory buffer is handled only by the reference model.

How To Do It (SPECMAN Code)

4. First declare a method to send the data. Collect a data item and send via this method. The function is declared as follows:
   
   ohd_mesByte : out method_port of ohd_clr_t is instance;
   keep bind(ohd_mesByte, empty);
   
   Collecting a data item is design specific and will not be shown.
5. In the receive side - the reference model declare an input method:
   
   ohd_message : list of byte;
   keep soft ohd_message.size() == 0;
   ohd_mesByte : in method_port of ohd_clr_t is instance;
   keep bind(ohd_mesByte, empty);
   ohd_mesByte(b : list of byte) is {
     ohd_message.add(b);
   };--ohd_mesByte
