  1. Hi Philipp, Great! Yes, it is better asking for the user input directly instead of pausing. Anyway, I was interested about this sc_pause, so I can do some testing with it. Vielen dank
  2. Hi everybody, I have a simple question (not so sure if the answer is simple too). Is it possible to "pause"/"halt" the simulation temporarily? It would be useful for me in two scenarios: Whenever the simulation reaches a specified point in the code. Just like a breakpoint, but not having the need to use a debugger. So whenever the user presses a key, the simulation goes on. Whenever the simulation reaches a point, where a user needs to send an input. It is similar to the previous one, but the here the user would need to enter an input (int, double, string, etc.). I understand that this may be harder for the simulation. So, any ideas? Is there any sc_pause? I know that there is a sc_halt, but it looks like it works only with threads, which would not be suitable to be called from an AMS module. Thanks a lot! ;-)
  3. 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); }; Until now I was adding an object, let's call it "tdf_some": #include <systemc-ams> class tdf_some_module : public sca_tdf::sca_module { public: sca_tdf::sca_in<int> in; sca_tdf::sca_out<int> out; tdf_some_module(sc_core::sc_module_name nm) {} void processing() { out.write( in.read() ); } }; Then, in the previous class I would change to: #include <systemc-ams> class some_module : public sc_core::sc_module { public: sca_tdf::sca_in<int> in; sca_tdf::sca_out<int> out; // Add new TDF module tdf_some *ts; some_module(sc_core::sc_module_name nm) { // Instantiate and bind ports ts = new tdf_some("ts"); ts->in(in); ts->out(out); } }; Looks like a very simple question (and I hope so), but I still haven't been able to solve it. Any ideas? Thanks
  4. Perfect! In the end was that silly problem Thanks a lot, maybe I would never have seen it
  5. Hi all! I have an error that I never had before with AMS. I have a few sc_modules with in and out TDF ports. Inside these sc_modules I have sca_modules, which are connected to those in and out TDF ports. This have been working fine until now, but I created a new class of module exactly the same way as the others and I have this error. I checked in the library and it seems like my sca_module is not assigned to any view: if (view_interface == NULL) { std::ostringstream str; str << "Error: " << name() << " a sca_module must be associated with a concrete view!" << std::endl; str << "It is not allowed to instantiate the sca_module base class." << std::endl; SC_REPORT_ERROR("SystemC-AMS",str.str().c_str()); } I know that maybe it not clear. I can give more details. But I am totally lost with this. Any ideas? Thanks
  6. It works I needed to update my SystemC version (from 2.2 to 2.3), but I finally made it! Thanks a lot Philipp!
  7. Hi all, I have been trying to do something that I'm not sure it's possible. I have some TDF modules that are connected to each other by sca_in and sca_out ports. All of this modules will have at least one of each in/out ports. My idea was that maybe some of them will have some extra in/out ports. For example, if I want two TDFs outputs to go to one TDF input, it is not possible using just one port. Instead, those TDF modules would have a vector of sca_in's so, if I need an extra port, this will be initialized and bound to a signal. All this is already done and compiling. My problem is that when I initialize and bind that new port, it is not specifically assigned to a TDF so I get this error: "Error: (E100) port specified outside of module: port 'sca_tdf_in_0' (sc_port_base)". I understand the reason of this error, but I would like to know if it is possible to assign this port to its TDF. Here I will show my code, maybe it's helpful. class 'gen' is a generator of doubles. It sends an increasing double through its 'out' port. class 'pass' is just getting whatever comes from its 'in' port and sending it out through its 'out' port. class 'waste' is where the 'magic' may be. Receives whatever which is coming from 'pass'. main.cpp: #include <systemc-ams> #include "gen.h" #include "waste.h" #include "pass.h" int sc_main(int argc, char *argv[]) { gen g("g"); pass p("p"); pass p2("p2"); waste w("w"); sca_tdf::sca_signal<double> sig("sig"); sca_tdf::sca_signal<double> sig2("sig2"); sca_tdf::sca_signal<double> sig3("sig3"); g.out(sig); p.in(sig); // Both 'p' and 'p2' receive from the same signal 'sig'. p2.in(sig); // This works perfectly. p.out(sig2); // The out port of both are bound to different signals. p2.out(sig3); // Otherwise, I would get an error. w.in(sig2); // This is a normal binding (to 'p' and 'sig') that works just fine. w.bind(sig3); // Here's where I want to implement my idea. Look at 'waste.h' sc_core::sc_start(500.0, sc_core::SC_MS); sc_core::sc_stop(); return 0; }; waste.h: #ifndef WASTE_H #define WASTE_H #include <systemc-ams> #include <vector> SCA_TDF_MODULE(waste) { sca_tdf::sca_in<double> in; // Main 'in' port std::vector<sca_tdf::sca_in<double>*> secondary_ins; // Vector of extra 'in' ports std::vector<sca_tdf::sca_in<double>*>::iterator it; // Iterator int ins; // Number of extra 'in' ports SCA_CTOR(waste) { it = secondary_ins.begin(); ins = 0; } // This initializes the extra 'in' port and adds it to the vector // Here should go the 'assignation' if it is possible. void new_in() { sca_tdf::sca_in<double> *sec_in = new sca_tdf::sca_in<double>(); secondary_ins.insert(it, sec_in); ins++; } // This method is called in 'main.cpp' and it might assign // the new 'in' port to the given signal void bind(sca_tdf::sca_signal<double> &s) { new_in(); secondary_ins.at(secondary_ins.size()-1)->bind(s); } void processing() { double d = in.read(); std::cout << name() << " - main_in : " << d << std::endl; for(int i=0; i<secondary_ins.size(); i++) { double d2 = secondary_ins.at(i)->read(); std::cout << name() << " - sec_in(" << i << "): " << d2 << std::endl; } } }; #endif So basically that's it. Any ideas? Is it even possible? Thanks a lot
  8. I tried that before, the problem is that it is not possible to have a resistor with the value 0 (I get an error). And I think it makes sense, because of the equation (there may be a divisio by zero?). Anyway, I will create a module like that with a very low non-zero value. Thanks again
  9. Lately, I have been dealing with some issues related to the ELN Networks. I am modelling some ELN modules as if they were completely independent, meaning that they can be connected to each other through its terminals no matter what modules it is connected to (considering, of course, the limitations of an ELN network). My problem is that sometimes I would like to have some kind of ELN Cable so I could connect an ELN Node to an ELN Ground (Node Ref), for example. Sounds crazy, but since I am creating a generic way of connecting these modules, sometimes I cannot directly connect a terminal to a ground. So, is there a way to avoid that problem since it is not possible to 'bind' a node? Would be useful to have an ELN Cable? Thanks a lot!
  10. I found out that is some kind of loop that I am creating in my module, among the ELN's and TDF's. Setting the vsink in parallel works fine.
  11. Ok, setting the vsink's in parallell with the resistors it works when it comes to the basic ELN. But in the configuration with my sc_modules: node_ref -> vsource -> node -> r -> node -> r -> node_ref |-> vsink ->| |-> vsink ->| I have the following error: I'm still not sure why
  12. Hi Karsten, Thanks for the answer. I may not be using the vsink in a proper way (maybe like isink). As I noted in the previous post, the sequence of my resultant electrical network is this: node_ref -> vsource -> node -> vsink -> node -> r -> node -> vsink -> node -> r -> node_ref If I'm doing it wrong, what should be the proper way to use a vsink and a resistor? Do I have to use a Reference Node instead of a simple node? Thank you again
  13. Hi everyone, I have been working with SystemC-AMS lately and having nice results, but now I'm facing some issues with the sca_eln::sca_tdf::sca_vsink module. I created some sc_modules with ELN modules inside. Quite briefly, the final electrical network (which I get from putting those sc_modules together) that I have been having problems with is: ELN: node_ref -> vsource -> node -> vsink -> node -> r -> node -> vsink -> node -> r -> node_ref SC :|-----GENERATOR-----|->|-----------PIPE-----------|->|----------PIPE------------| -> |---SINK---| If understood correctly the sca_eln::sca_tdf::sca_isink module is like a voltage source with v = 0 V, so they should not be connected in parallel. I do not know if the vsink works in a similar way, being a current source, so there should not be two connected in a row. Taking a look at the Users guide it is noted for both modules that "No equation added to the equation system", so I'm not sure if this is a conflict because of what I just mentioned. The error I'm getting is: I would like to know the reason why this is not working, if anyone happen to find any The idea of having vsink's there is because I want to send the value from the electrical network in that spot to a TDF module. I'm not sure if this is ok or is a crazy idea. I hope I explained everything clearly, otherwise, just ask and I'll try to do it better Thanks a lot! Kike
