  1. 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 abl´╗┐e to find solutions on the link provided in the textbook. Thanx in advance. Regards, Veeresh K

    clock generation in system c

    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 }
  3. Dear Sir, I am getting the following errors in running this program: error C2466: cannot allocate an array of constant size 0 error C2133: 'matrix' : unknown size Assume I am getting m and n through functions already written and declared in constructor. SC_MODULE(sc_fifo_array) { public: SC_HAS_PROCESS(sc_fifo_array); sc_fifo_array(sc_module_name name_):sc_module(name_) { int m,n; int *matrix[m]; for (int i=0; i<m; i++) matrix=new int[n]; matrix[0][0]=20; cout<<"\nmatrix="<<matrix[0][0]<<"\n"; } public: int m,n; }; Does system C does not support variable size matrix?

    Errors in code

    Hi Attached is the code for parallel to serial and serial to parallel conversion i have two problems in converter.cpp 1- count is not incrementing the value 2- Lout is not getting value of PS_reg in SPPS48 i am getting the following error ./../../SPPS48.h: In constructor 'SPPS48::SPPS48(sc_core::sc_module_name)': ../../../SPPS48.h:51:9: error: 'struct SPPS48' has no member named 'M1' ../../../SPPS48.h:51:16: error: expected type-specifier before 'SPPS' ../../../SPPS48.h:51:16: error: expected ';' before 'SPPS' ../../../SPPS48.h:52:3: error: 'M1' was not declared in this scope ../../../SPPS48.h:60:3: error: 'M2' was not declared in this scope ../../../SPPS48.h:60:10: error: expected type-specifier before 'SPPS' ../../../SPPS48.h:60:10: error: expected ';' before 'SPPS' ../../../SPPS48.h:69:3: error: 'M3' was not declared in this scope ../../../SPPS48.h:69:10: error: expected type-specifier before 'SPPS' ../../../SPPS48.h:69:10: error: expected ';' before 'SPPS' convert.cpp main.cpp SPPS.h SPPS48.h

    Reading a binary File

    Hello I wand to read the binary file in System C. Can I use the malloc() function as we used in C to store the content of the file in some buffer. Thanks. The fread() command is used in System C or there is some other command in System C.
  6. hai to all Iam karthik,doing my masters in VLSI DESIGN ,i found my interest in system level design and i wish to do project in systemcTLM based simulation.As a starter ,learning systemC language and i want to learn how systemc TLM differ by verilog,VHDL and other languages by results.i.e by simulation...kindly guide me regarding by suggesting some projects or papers in these domains.. keywords:co-simulation,systemc based simulations..
