how to connect modules inside another module

[JorgeAbarca]

i have a module called dispenser, which is my top hierarchy module and it has tow sub modules inside (module1 and module2). how can i connect them inside my main module ?

i have tried something like this and it is failing. know that it is possible to do it using Pointers, but i am trying in this way. how can i do it? 

SC_MODULE(dispenser){

sc_in<bool> input1; 

sc_in<bool>input2; 

sc_out<bool>out1;

sc_signal<bool> s1;

 

SC_CTOR(dispenser){

 

module1 m1("module1");

m1.in1(input1);

m1.in2(input2)

m1.outA(s1);

 

module2 m2 ("module2");

m2.input1(input1);

m2.input2(s1);

m2.out(out1);

      }

 

}

You declare your modules as local variables in the constructor. Leaving the constructor they are destroyed. Something like this should work:

SC_MODULE(dispenser){
    sc_in<bool> input1; 
    sc_in<bool>input2; 
    sc_out<bool>out1;
    sc_signal<bool> s1;
    module1 m1;
    module2 m2;

    SC_CTOR(dispenser): input1("input1"), input2("input2"), out1("out1"), s1("s1"), m1("module1"), m2("module2") {
      m1.in1(input1);
      m1.in2(input2)
      m1.outA(s1);
      m2.input1(input1);
      m2.input2(s1);
      m2.out(out1);
    }
};

I highly advice to name all signals and ports. If you start debugging this will ease you live. If you are using newer versions of SystemC you can write it like:

SC_MODULE(dispenser){
    sc_in<bool> input1; 
    sc_in<bool>input2; 
    sc_out<bool>out1;
    sc_signal<bool> s1;
    module1 m1;
    module2 m2;

    SC_CTOR(dispenser): SC_NAMED(input1), SC_NAMED(input2), SC_NAMED(out1), SC_NAMED(s1), SC_NAMED(m1), SC_NAMED(m2) {
      m1.in1(input1);
      m1.in2(input2)
      m1.outA(s1);
      m2.input1(input1);
      m2.input2(s1);
      m2.out(out1);
    }
};

If you compile using C++11 you can also doing it like this:

SC_MODULE(dispenser){
    sc_in<bool> input1{"input1"}; 
    sc_in<bool>input2{"input2"}; 
    sc_out<bool>out1{"out1"};
    sc_signal<bool> s1{"s1"};
    module1 m1{"m1"};
    module2 m2{"m2"};

    SC_CTOR(dispenser){
      m1.in1(input1);
      m1.in2(input2)
      m1.outA(s1);
      m2.input1(input1);
      m2.input2(s1);
      m2.out(out1);
    }
};
