Hi, I assume its a basic question . Can someone please help me understand the basic flow of initiator and target by using a blocking interface in a c++ way. I had read the tutorial on doulous ,but i dint get the required explnation from my side. I do know the concepts of c++,but implementation wise i am bit on the slower side. It would be great if someone could explain it here through step wise. Thanks in advance. Ps: just for reference i am putting up the code.initiator.h,target.h,top.h,main.cpp Regards, Shubham

Hey everyone, As of now , i am reffering textbook "SYSTEM C-FROM THE GROUND UP". I am finding that textbook very helpful and wanted to go through the solutions of example problems given in that book. If am able to figure out my approach is right or wrong ,then it would be very helpful in getting much proficient with system c. Can anyone,please tell me where can i find them? I am not able to find solutions on the link provided in the textbook. Thanx in advance. Regards, Veeresh K

Hi , I am trying to trace out the wave for the input and the output. I have tried for different ways,but not getting the desired results. One of the way was,i created 2 same signals with diff. name in testbench file and tried to trace ,but i was not successful in doing so. Any suggestions to do? Thank you. ? Ps:- I have attached the code through which m trying to trace.Plz,help me out with this.I have modified the code according to the errors,So thats the reason for using namespace sc::core while declaring fifo tracing input.I am posting full code along with the errors. /////////ERRORS///////////////////////////////////// testbench.cpp: In function 'int sc_main(int, char**)':testbench.cpp:16:18: error: no match for call to '(sc_core::sc_fifo<sc_dt::sc_int<32> >) (sc_core::sc_fifo_in<int>&)'testbench.cpp:17:19: error: no match for call to '(sc_core::sc_fifo<sc_dt::sc_int<32> >) (sc_core::sc_fifo_out<int>&)'testbench.cpp:21:29: error: no matching function for call to 'sc_trace(sc_core::sc_trace_file*&, sc_core::sc_fifo_in<int>&, const char [6])' ////////////////////CODE///////////////////////////// #ifndef EXAMPLE_H #define EXAMPLE_H using namespace sc_dt; typedef sc_int<32> sc_int32; SC_MODULE(example) sc_fifo<sc_int32> fifo; //producer thread void producer_thread(); //consumer thread void consumer_thread(); SC_CTOR(example) : fifo(2) { SC_THREAD(producer_thread); SC_THREAD(consumer_thread); }; }; #endif ///////////////////////////////////////// #include <systemc.h> #include "example.h" using namespace sc_dt; void example::producer_thread() { int unsigned number_of_accesses = 4; for (int i = 0; i < number_of_accesses; i++) { sc_int32 value(i); cout << "[" << sc_time_stamp() << "] writing to FIFO value: " << value << ", free: " << fifo.num_free() << endl; fifo.write(value); cout << "[" << sc_time_stamp() << "] wrote to FIFO value: " << value << endl; wait(1, SC_NS); } } //consumer thread void example::consumer_thread() { sc_int<32> value(0); for (;;) { wait(4, SC_NS); fifo.read(value); cout << "[" << sc_time_stamp() << "] read from FIFO value: " << value << endl; } } ////////////////////////////////////////////////MAIN.CPP//////////////////// #include "systemc.h" #include "example.h" using namespace sc_dt; int sc_main(int, char* []) { sc_core::sc_fifo_out<int> output1; sc_core::sc_fifo_in<int> input1; //create the instance of the example example eg1("example_inst"); eg1.fifo(input1); eg1.fifo(output1); sc_trace_file*tf=sc_create_vcd_trace_file("fi"); sc_trace(tf,input1,"input"); sc_trace(tf,output1,"output"); sc_start(); if(not sc_end_of_simulation_invoked()) { sc_stop; } sc_close_vcd_trace_file(tf); return 0; }

Hi. I have taken this example from a book and tried to execute it,But i got few errors. I have compared this code with std 2011 and made changes according to that like using namspace sc_core . I am not able to find a right solution for this one. Can someone plese help me out with this.I have posted the code below along with the error,check it out. Thank you. //error////////// In file included from testbench.cpp:6:0:head1.h: In member function 'void www::woperation()':head1.h:16:9: error: 'class sc_core::sc_port<sc_core::sc_fifo_out_if<int> >' has no member named 'write'In file included from testbench.cpp:7:0:head2.h: In member function 'void rrr::roperation()':head2.h:17:9: error: 'class sc_core::sc_port<sc_core::sc_fifo_in_if<int> >' has no member named 'read'  ////////code///// #include<systemc.h> #include"Head1.h" #include"Head2.h" int sc_main(int argc, char* argv[]) { sc_fifo<int> fifo(10); writer w("writer"); reader r("reader"); w.out(fifo); r.in(fifo); sc_start(-1); return 0; } //header1 #include<systemc.h> SC_MODULE(reader) { sc_port<sc_fifo_in_if<int> > in; void roperation() { int val; while (true) { wait(10, SC_NS) for (int i = 0; i <= 15; i++) { in.read(val); cout << val << endl; } } cout << "Availaible : " << in.num availaible() << endl; } SC_CTOR(writer) { SC_THREAD(woperation); } }; //header2 #include<systemc.h> SC_MODULE(writer) { sc_port<sc_fifo_out_if<int> > out; void woperation() { int val = 0; while (true) { wait(10, SC_NS); for (int i = 0; i <= 20; i++) { out.write(val++); } } } SC_CTOR(writer) { SC_THREAD(woperation); } };

Hi, I have came across this counter example from other website. Can u please tell me ,where have we intitialised the main clock. I know the default time period is 1ps,but i am not getting the start of the clock is from which point. I am not knowing the reason for its generation in waveform viewer. Thank you. Below is the code: #include "systemc.h" #include "design.cpp" int sc_main (int argc, char* argv[]) { sc_signal<bool> clock; sc_signal<bool> reset; sc_signal<bool> enable; sc_signal<sc_uint<4> > counter_out; int i = 0; // Connect the DUT first_counter counter("COUNTER"); counter.clock(clock); counter.reset(reset); counter.enable(enable); counter.counter_out(counter_out); sc_start(1, SC_NS); // Open VCD file sc_trace_file *wf = sc_create_vcd_trace_file("counter"); // Dump the desired signals sc_trace(wf, clock, "clock"); sc_trace(wf, reset, "reset"); sc_trace(wf, enable, "enable"); sc_trace(wf, counter_out, "count"); // Initialize all variables reset = 0; // initial value of reset enable = 0; // initial value of enable for (i=0;i<5;i++) { clock = 0; sc_start(1, SC_NS); clock = 1; sc_start(1, SC_NS); } reset = 1; // Assert the reset cout << "@" << sc_time_stamp() <<" Asserting reset\n" << endl; for (i=0;i<10;i++) { clock = 0; sc_start(1, SC_NS); clock = 1; sc_start(1, SC_NS); } reset = 0; // De-assert the reset cout << "@" << sc_time_stamp() <<" De-Asserting reset\n" << endl; for (i=0;i<5;i++) { clock = 0; sc_start(1, SC_NS); clock = 1; sc_start(1, SC_NS); } cout << "@" << sc_time_stamp() <<" Asserting Enable\n" << endl; enable = 1; // Assert enable for (i=0;i<20;i++) { clock = 0; sc_start(1, SC_NS); clock = 1; sc_start(1, SC_NS); } cout << "@" << sc_time_stamp() <<" De-Asserting Enable\n" << endl; enable = 0; // De-assert enable cout << "@" << sc_time_stamp() <<" Terminating simulation\n" << endl; sc_close_vcd_trace_file(wf); return 0;// Terminate simulation }

Hi, I am new to system c. I am trying to learn it step by step,but getting messed up with arrival of every new topic. Any suggestions for good book ? Currently i am studying system c primer by J.Bhasker. Please, help me out. Thank you.

Can someone please explain with a simple example of up/down counter?
