JorgeAbarca Posted March 7, 2020 Report Share Posted March 7, 2020 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); } } Quote Link to comment Share on other sites More sharing options...
Eyck Posted March 7, 2020 Report Share Posted March 7, 2020 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); } }; Quote Link to comment Share on other sites More sharing options...
