Hi:

And I see it also works with public derive two sc_module?

So
"you are trying to inherit multiple times from sc_module.  In short, this
is not allowed in SystemC"
why I still can run?


#include <iostream>
#include "systemc"
#include <vector>
using namespace std;
using namespace sc_core;



class a: public sc_module {
public:
        void run(){
                cout<<"I am here in a"<<endl;
        };
        SC_HAS_PROCESS(a);
        a(sc_module_name na):sc_module ("a"){SC_THREAD(run)};
};
class b: public sc_module {
public:
        void test(){
                                cout<<"I am here in b"<<endl;
                        }
        SC_HAS_PROCESS(b);
        b(sc_module_name na):sc_module ("b"){SC_THREAD(test);};
};

class c: public a, public b {
public:

        c(sc_module_name na):a(na),b(na){};
};

int sc_main ( int argc, char **argv ) {

       c m1("master1");
       sc_start();
       return 0;
}

Thank you very much
