Dear Sir, I am new to SystemC. Pl. advise how to access ex1[0] etc. in the following program: #include "systemc.h" #include <stdio.h> SC_MODULE(exfifo) { SC_CTOR(exfifo) { SC_METHOD(fifo_pop); sc_fifo<int> packet_fifo(5); } void fifo_pop(void) { int val; if ((ex1[0].packet_fifo).nbread(val)) cout << "\n hi \n"; WAIT(2, SC_NS); } 　 }; 　 　 int sc_main(int argc, char* argv[]) { cout << "Maha Ganapatim Veera Nangai Gnanananda\n"; sc_vector<exfifo>("ex1", 4); sc_start(10, SC_NS); return 0; } Throwing ex1 undeclared identifier. Left side of packet_fifo must have class/struct/union Appreciate your help. If things are to be done differently, pl. indicate complete steps as I am a newbie. Thanks.

Hallo, i have been trying to change de defalut sc_fifo size, but i dosen´t work at all. main.cpp sc_fifo<ressource> ff_in_ch; // ressource si a self-defined data-type class X sc_fifo_out<ressource> ffin; class Y sc_fifo_in<ressource> ffin; How can i change the size of the sc_fifo? I have tried this: sc_fifo<ressource> ff_in_ch(64); but it dosen´t work at all. Thanks in adavanced!

Hi all, I created two modules with interfaces as below: M1 : sc_port<sc_fifo_out_if<T>, 0> a M2 : sc_port<sc_fifo_in_if<T>, 0> a2; I have a third module which is also my top module i.e M3 and tried binding M1 output to M2 input to create a communication channel. I have tried using sc_fifo<T> but it doesn't work. How do I bind M1 output to M2 input inside M3 module? Please not that T is a struct. Thanks

Hi everyone, I'm met some problem. In box below you can see my code. struct Some_stuct { int data; float data_f; }; class payload_t { public: unsigned char *data; unsigned lenght; inline friend ostream& operator << ( ostream& os, payload_t const & v ) { os << "(" << v.data << "," << std::boolalpha << "," << v.lenght << ")"; return os; } }; SC_MODULE(tx) { sc_port<sc_fifo_out_if<payload_t> > out_port; void process() { Some_stuct data; payload_t out_data; while(true) { data.data = 5; data.data_f = 6; out_data.data = reinterpret_cast<unsigned char*>(&data); out_data.lenght = sizeof(Some_stuct); out_port->write(out_data); data.data++; data.data_f++; wait(1, SC_NS); } } SC_CTOR(tx) { SC_THREAD(process); } }; SC_MODULE(rx) { sc_port<sc_fifo_in_if<payload_t> > in_port; void process() { int realData = 0; payload_t in_data; while(true) { wait(in_port->data_written_event()); wait(171, SC_NS); in_data = in_port->read(); Some_stuct *val = reinterpret_cast<Some_stuct*>(in_data.data); cout << sc_time_stamp() << " " << val->data << " " << val->data_f << endl; } } SC_CTOR(rx) { SC_THREAD(process); } }; int sc_main(int argc, char* argv[]) { rx rx_i("rx"); tx tx_i("tx"); sc_fifo<payload_t> buf(8); tx_i.out_port(buf); rx_i.in_port(buf); sc_start(); getchar(); return 0; } I'm have two blocks: transmitter and receiver. When we call method write to fifo from transmitter, actually we will send address of our local data. And when i will read from buffer, I will receive address of transmitter local data. But if transmitter works more faster than receiver, my rx block will receive "New" data and sended data will loss. How to solve this problem? I should receive correct data

Hi all, I am defining the sc_fifo as, sc_fifo<sc_lv<FLIT_SIZE> > fifo_rx1 (BUFFER_SIZE); and BUFFER_SIZE and FLIT_SIZE are defined in another header file as, const unsigned int FLIT_SIZE = 39; const int BUFFER_SIZE = 50; The problem I encounter is, whenever I change the BUFFER_SIZE, I do not get any change in the performance of my system. And I checked that sc_fifo is getting defined at default size of 16 (with num_free() ). As I understand the size_ variable in sc_fifo class is of int type, so I am not sure what is the problem exactly, Help is appreciated. Thank you. Sincerely, Gurunath

Hello All, I have a question about determining the source of event for a module (module_a) connected to multiple modules (module_b1, module_b2, and module_b3) through sc_fifos (sf_b1_to_a, sf_b2_to_a, and sf_b3_to_a). module_a has a process that processes both clocked and non-clocked events. I use clk.posedge() to determine the source of clocked and non-clocked events. The process in module_a is made sensitive to clk.pos(), sf_b1_to_a.data_written(), sf_b2_to_a.data_written(), and sf_b3_to_a.data_written(). The problem is when the module_a process is triggered due to one of the non-clocked events (i.e., sf_b1_to_a.data_written(), sf_b2_to_a.data_written(), or sf_b3_to_a.data_written()) I don't know how to determine which one actually triggered the module_a process. I have an idea to determine the source of the event. I'd like to validate my idea. My idea is that I use a global fifo, and when any of modules module_b1, module_b2, or module_b3 write to the corresponding sc_fifo, write its ID to the global fifo as well. Then, when module_a is triggered for a non-clocked event, I read the global fifo and determine which fifo has written to the global fifo. Is this a valid assumption that the order that modules b1, b2, and b3 write to the global fifo, the same as the order that the SystemC kernel triggers module_a for their respective data_written() events? Thank you so much in advance! Regards, Alireza

Hell All, I posted a question entitled "Determining source of events using global fifo" on Sep 9, 2013. Surprisingly, I have not got a reply for this post so far. What is wrong with this post? Any idea? Can anyone see my post? Thanks, Alireza

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
