Accessing channel via port

[Tim_]

Hello,

 

the class sc_port offers the function get_interface().

Is there also an option to get the bound channel?

 

Cheers!

Hello,

 

I am interested in getting the address of a channel during the binding.

So, I have modified the bind function of the class class sc_port_b in this way to the see address:

    SC_VIRTUAL_ void bind( IF& interface_ )
	{
    std::cout << "Address in bind: " << &interface_ << std::endl;
    base_type::bind( interface_ ); }

And I use this sender/receiver example:

#include "systemc.h"

class Sender: public sc_module {

public:

  sc_fifo_out<int> fifo_out;

  SC_HAS_PROCESS(Sender);

  Sender(sc_module_name mn):
    sc_module(mn)
  {
    SC_THREAD(main);
  }

  void main()
  {
    for(int i=0; i<50; i++) {
      std::cout << "writing " << i << std::endl;
      fifo_out.write(i);
    }
  }
};


class Receiver: public sc_module {

public:

  sc_fifo_in<int> fifo_in;

  SC_HAS_PROCESS(Receiver);

  Receiver(sc_module_name mn):
    sc_module(mn)
  {
    SC_THREAD(main);
  }

  void main()
  {
    while(true) {
      int value = fifo_in.read();
      std::cout << "read " << value << std::endl;
    }
  }
};

class Top: public sc_module {

public:

  Sender sender_;
  Receiver receiver_;
  sc_fifo<int> fifo_;

  Top(sc_module_name mn):
    sc_module(mn),
    sender_("sender"),
    receiver_("receiver")
  {  }

  void before_end_of_elaboration()
  {
    sender_.fifo_out.bind(fifo_);
    receiver_.fifo_in.bind(fifo_);
  }
};

int sc_main(int argc, char **argv)
{
  Top t("top");
  std::cout << &t.fifo_ << std::endl;

  sc_start();

  return 0;
}

My output (without the read/write messages) looks like this one:

0x7fff82b16d70
Address in bind: 0x7fff82b16d80
Address in bind: 0x7fff82b16d70

Can somebody help me out and explain to me why the address is different in the second binding?

I appreciate any help

 

 

Best regards,
