    system c beginner

    Here is a short list of topics in no particular order you need to be comfortable with in order to be have an easier time learning SystemC: [Note: Others might chime in with variations on this list (add/subtract), and this is not necessarily a complete list, but I am fairly certain if you are able to comfortably use the topics I list below, you will have very little trouble syntactically with learning SystemC. In addition to C++, it helps if you have some familiarity with event driven simulation (e.g. SystemVerilog or VHDL). Also, if you have deep knowledge in another OO language (e.g. Java or SystemVerilog), you might have an easier time learning the C++ part.] Difference between declaration and definition Pass by value vs pass by reference Use of const (5 distinct cases) Casting C++ style (4 types) Implicit vs explicit conversions Use of function overloading and how to deal with ambiguity issues Use of std::string Use of streaming I/O How to declare, define and use classes Definition of default constructor Purpose and syntax of copy constructor How to declare and use namespaces Operator overloading as member functions and global functions. The difference between overloading and overriding. Relationship between class and struct How to extend classes and multiple inheritance Purpose of public and private Storage types and lifetimes: static, automatic, dynamic How to properly use new and delete Use of pointers and understanding of issues with pointer arithmetic Use of arrays and issues Advantages and use of std::vector<> Use of try-catch and throw Use of initializer list in constructor and a proper understanding of the order of construction Polymorphism and RTTI RAII Rule of 4 (6 if using C++11 or later) How and where to define templates/generic programming (does not need to be deep knowledge - just the basics) Use of templates and nested templates. Definition of full and partial template specialization. Different types of constructors and destructors Use of virtual inheritance (hint: it's not polymorphism) Extra topics: More STL including at least std::map<>, std::set<> Boost Modern C++ users (2011 onward) should know about: nullptr Uniform initialization Use of auto Use of ranged for Lambda definition, binding and use constexpr std::unique_ptr<>m std::shared_ptr<>

    clock generation in system c

    Hello @veeresh k, This example does not have a dedicated clock generator. // These statements are what driving the clock signal to with High time of 1 ns and low time of 1 ns. for (i=0;i<10;i++) { clock = 0; sc_start(1, SC_NS);// Run simulation for 1 ns. clock = 1; sc_start(1, SC_NS);// Run simulation for 1 ns. } What message you receive from the SystemC kernel refers to the timescale of 1 ps e.g.: Info: (I702) default timescale unit used for tracing: 1 ps You can get the SystemC API documentation for the sc_clock from here: SystemC sc_clock api reference. If you need a sample you can find a use-case reference here(though a little bit-dated): https://github.com/AmeyaVS/SystemC_ramblings/blob/ff1a111063842bfcd6f5de6bb3db74917dc6331c/src/03_fir/firsytemmain.cpp#L26 Hope it helps. Regards, Ameya Vikram Singh

    First, make sure that you are proficient in C++ as SystemC is a C++ library, which makes extensively use of advanced C++ features! Then, read a good introductory book on SystemC. I am personally not familiar with the SystemC Primer so cannot judge it. I found the book "SystemC from the Ground Up" by David C. Black, Jack Donovan et al. very helpful to learn SystemC.
