Hello Forum, I want to have std::list<int> as type for a sc_port and sc_signal. In the e-book "SystemC : From The Ground Up" and "IEEE Std 1666™-2011" I found the necessary information. So I created a wrapper class that implements the necessary overloaded operators, and the sc_trace function that are needed for this purpose. // List that is traceable by sc_trace class TraceList { private: std::list<int> lst; public: // Methods for accessing list std::list<int>& read() { return lst; } void write(std::list<int> var) { lst = var; } // CTOR TraceList() { } // CTOR for init values TraceList(std::list<int> var) { lst = var; } // Required by sc_signal<> and sc_fifo<> TraceList& operator= (const TraceList& var) { lst = var.lst; return *this; } // Required by sc_signal<> bool operator== (const TraceList& var) const { return lst == var.lst; } // Required functions by SystemC friend ostream& operator<< (ostream& os, const TraceList& var) { os << "{"; auto it = var.lst.begin(); while (it != var.lst.end()) { os << *it; it = std::next(it); } os << "}"; return os; } void sc_trace(sc_trace_file* tf, const TraceList& var, const std::string& nm) { int pos = 0; auto it = var.lst.begin(); while (it != var.lst.end()) { // use namespace, compiler otherwise chooses wrong function sc_core::sc_trace(tf, *it, nm + std::to_string(pos++)); it = std::next(it); } } }; I get these kind of errors: Severity Code Description Project File Line Suppression State Error C2665 'sc_core::sc_trace': none of the 60 overloads could convert all the argument types

Hi, I wish to perform a trace for all the signals in my design. Since I didn't find a reference how to do this, I tried to implement it by myself. The main concept I used is to run recursively on all child objects of sc_module objects (using the get_child_objects() method). If a child object is sc_signal, the sc_trace method is performed. I created a test-case and ran it with Accellera compiler 2.3. However, I'm getting the following warning: Warning: (W710) object cannot not be traced: system.sig In file: ..\..\src\sysc\tracing\sc_trace.cpp:145 Could you please help me to fix the code? Regards, Ness case_system.h case_walker.h case_system.cpp case_walker.cpp sc_main.cpp

Hi, I have a query regarding sc_trace. Is it possible to have directly get all the signals and ports dumped into the VCD file. I am trying something like this in sc_main: Top top1("top1"); sc_trace_file *tf = sc_create_vcd_trace_file("waveforms"); sc_simcontext *context = sc_get_curr_simcontext(); sc_object *optr = context->first_object(); while(optr) { if (std::string(optr->kind()) == "sc_signal") optr->trace(tf); optr = context->next_object(); } With this I am not getting anything into the waveforms.vcd. Could anyone please suggest the correct way to do the above. Thanks for the help. -- Samyak Jaroli Student, India

Dear all, is it possible to apply standard SystemC tracing to tlm_extensions? I defined my own tlm extension to add a reset and a value fields to the standard payload: class reg_extension : public tlm::tlm_extension<reg_extension>{ public: reg_extension(); tlm::tlm_extension_base* clone() const ; void copy_from(tlm::tlm_extension_base const &); bool reset; sc_bv<16> value; }; Then, my testbench declares and uses it to carry data to/from the target: class testbench : public sc_module , public virtual tlm::tlm_bw_transport_if<> { public: tlm::tlm_initiator_socket<> initiator_socket; reg_extension * payload_data; ... } void testbench::run() { tlm::tlm_generic_payload * trans; sc_time time; mem = new mem_manager(); trans = mem->allocate(); payload_data = new reg_extension; payload_data->value = sc_bv<16>("00001111"); payload_data->reset = 1; trans->set_data_length(sizeof(register_data_t)); trans->set_auto_extension(payload_data); trans->set_address(0); trans->set_write(); initiator_socket->b_transport(*trans, time); ... } In my main, I try to apply standard tracing: int main(int argc, char* argv[]) { toplevel top("top"); sc_trace_file* fp = sc_create_vcd_trace_file("wave"); fp->set_time_unit(1, SC_NS); sc_trace(fp, top.tb.payload_data->reset, "reset" ); sc_trace(fp, top.tb.payload_data->value, "value" ); sc_start(); sc_close_vcd_trace_file(fp); return 0; } The code compiles correctly, but: with SystemC 2.2.0, the generated trace is weird (see attached - I truncated the value as it had far too many digits) things get worse when compiling with SystemC 2.3.0, as the execution returns this error: My impression is that memory is somehow not managed - this would explain the wrong size for the value field, the huge correponding value, and the bad_alloc. Please note that I forced some wait invocations to advance simulation time, so that write operations onto the extension fields occur at different simulation times. Thank you in advance, Regards, S. wave.vcd

How to output "float (double)" from sc_fixed type class using sc_trace? I have an existing model (all in floating point design, using "sc_signal<double>"), and am trying to convert it to its fixed point one (i.e. using sc_signal<sc_fixed< ,,,, > >"). sc_signal<double> ch_a; sc_signal<sc_fixed<16,8, SC_RND, SC_SAT> > ch_a_fix; sc_trace(tf, ch_a, "ch_a" ); // floating point channel tracing, it traces signal in "double". sc_trace(tf, ch_a_fix, "ch_a_fix ); // fixed point channel tracing: it traces signal in "integer numbers". The question is, how can I trace the sc_fixed type class (sc_signal<sc_fixed<...:> >) in floating point numbers? For waveform viewer-wise, I'm using gtkwave for now. I have found one posting that has the same question that I have now. But it doesn't have any replies there. http://www.accellera.org/Discussion_Forums/helpforum/archive/msg/msg?list_name=help_forum&monthdir=200802&msg=msg00035.html Many thanks in advance.
