yatung Posted January 23, 2013 Report Share Posted January 23, 2013 Hello Everyone, I am a beginner at systemc. I am interested in sc_fifo channel and investigated the OSCI simulator source code. I found sc_fifo has a member function named "data_written_event" and its prototype is like below: virtual const sc_event& data_written_event() const; I want to get a callback/notify when a specific sc_fifo channel is written or read. My solution is: - Preface I used the sc_get_top_level_objects() and get_child_objects() to iterate out all the sc_object. (This is the way I get the sc_fifo object) - Make a callback/sensitive by user code 1. Try to get the written/read event data member of sc_fifo 2. Use the add_static() member function of sc_event to register a written/read event callback for this sc_fifo Is the solution above workable? ---------------------------------------------- - My Test Result 1. Try to get the written/read event data member of sc_fifo ==> Because of the "operator=" is overwritten as private: sc_fifo& operator = ( const sc_fifo<T>& ); I canNOT get the event in user code. ex: sc_event e; e = sc_fifo_obj->data_written_event(); //<-- Error! Of course. 2. add_static() is s private member function of sc_event class and I can neither use it in user code. Can you experts guide me how to do it or give me any hint? Appreciate your feedback. by yaTung Quote Link to comment Share on other sites More sharing options...
