  1. SOLVED: Nevermind, I made some mistakes in calling the wrong methods for writing/reading from ports. Thanks for your attention anyway! I'm trying to implement this example of a memory and a cpu that are communicating. CPU <==> MEM The modules use a single bidirectional data-line for reading/writing. I defined a signal in sc_main: sc_signal<int,SC_MANY_WRITERS> s_memdata; which I connect to the CPU and MEM module through their ports: sc_inout<int> p_memdata; The CPU is writing to the s_memdata signal: p_memdata.write(getrnddata());
  2. Dear reader, I recently started exploring SystemC and SystemC AMS. I'm working through this presentation/tutorial by TU Delft. I'm trying to connect two SCA_TDF modules through a sca_tdf::sca_signal to build the Binary Amplitude Shift Keying modulator. In the constructor of my 'transmitter' I creating two instantiations of a 'mixer' and a 'sine'. mix = new mixer("mixer", rate ); mix->in_bit(in); mix->carrier(wave); mix->mixed(out); sin = new sine("sin", freq, rate ); sin->out(wave); Whereas signals, ports and pointers of this transmitter are define
  3. Hello to everybody, I would like to know some more information about signals offered by SystemC. How does the signal's structure look like? Is it allocated as an array of data ? Is it just a variable? Do signals have any overhead? For instance what will happen if I use 5000 signals? Thank you in advance !!!!
  4. Hi again! Maybe this is too obvious, but I've been wonderin for a while now and never found the answer (and dared to ask for it ). Is it possible to directly pass whatever comes from an tdf_in port to a tdf_out port? Not only that, is it possible to do it in a sc_module instead of a sca_module? For a better explanation I'll leave a piece of code. Let's say I have: #include <systemc-ams> class some_module : public sc_core::sc_module { public: sca_tdf::sca_in<int> in; sca_tdf::sca_out<int> out; some_module(sc_core::sc_module_name nm); }
