TLM Sockets

[rahuljn]

Hi Guys

Is it possible to connect one tlm_initiator_socket to more than one tlm_target_socket and vice versa.

If no, why?

And what about one tlm_initiator_socket to more than one tlm_initiator_socket upward in the hierarchy

Same question for simple sc_in/sc_out

Thanks

Rahul

1. Yes, see LRM 13.2.4 r)

2. No, see LRM table 60

3. You can connect one sc_in to drive many sc_out, but not the other way round. See the description of sc_writer_policy at LRM 6.3

Hi Alain

 

I have a initiator module with

tlm::tlm_initiator_socket<BUS_WIDTH,tlm::tlm_base_protocol_types,2> initiator_socket;
and a target module with

tlm::tlm_target_socket<BUS_WIDTH> target_socket1;
tlm::tlm_target_socket<BUS_WIDTH> target_socket2;

 

And in top, I have

initiator_inst->initiator_socket.bind(target_inst->target_socket1);
initiator_inst->initiator_socket.bind(target_inst->target_socket2);

 

When I run this, it says

Error: (E107) bind interface to port failed: interface already bound to port: port 'initiator.tlm_base_initiator_socket_0' (tlm_initiator_socket)
 

 

But when I have a initiator module with

tlm::tlm_initiator_socket<BUS_WIDTH> initiator_socket;

and a target module with

tlm::tlm_target_socket<BUS_WIDTH,tlm::tlm_base_protocol_types,2> target_socket;

and in top I have tow instance of initiator and connected to target like

initiator_inst1->initiator_socket.bind(target_inst->target_socket);
initiator_inst2->initiator_socket.bind(target_inst->target_socket);

 

It works fine.

Why the Ist case above is not working ?
