Graph Generation

Hello All,

Using get_chil d_objects() I can traverse through hierarchy and can find any ports & instances

But I cannot find how these ports are connected. All what I want to do is to create a database which I can use for visualization by post processing.

Is there any way to do this ?

Regards,

Sumit

In some cases yes, you can do it by playing with dynamic casts. For example:

#include <systemc.h>

SC_MODULE(test) {
    sc_signal <int> xsig{"xsig"};
    sc_signal <unsigned> xsig2{"xsig2"};
    sc_in <int> xin{"xin"};
    sc_out <unsigned> xout{"xout"};

    SC_CTOR(test) {
        xin(xsig);
        xout(xsig2);
    }
};

int sc_main(int argc, char **argv) {
    test t0{"t0"};
    sc_start(SC_ZERO_TIME);

    cout << hex;

    for (auto * obj : t0.get_child_objects()) {
        cout << obj->kind()  << " " << obj->name() << " @ " << obj;

        if(sc_port_base* port = dynamic_cast<sc_port_base*>(obj))
            if (sc_prim_channel * chan = dynamic_cast<sc_prim_channel*>(port->get_interface()))
                std::cout << " ( binded to " << chan->name() << " @ " << chan << ")";
        cout << endl;
    }

    return 0;
}

Possible output:

sc_signal t0.xsig @ 0x111f878
sc_signal t0.xsig2 @ 0x111f938
sc_in t0.xin @ 0x111f9e8 ( binded to t0.xsig @ 0x111f878)
sc_out t0.xout @ 0x111fa90 ( binded to t0.xsig2 @ 0x111f938)

SystemC however does not store information about hierarchical bindings.
