The original C++ code

#include "systemc.h"

using namespace sc_core;

// Virtual and non-virtual unction call with cast to base module type

struct A : public sc_module
{
    A(const sc_module_name& name) : sc_module(name)
    {}
    
    void f() {
        char m = 1;
    }
};


class C : public A 
{
public:
    sc_signal<bool> dummy{"dummy"};

    SC_HAS_PROCESS(C);
    C(const sc_module_name& name) : A(name) {
        SC_METHOD(proc_func); sensitive << dummy;
    }
    
    void f() {
        short m = 2;
    }

    void proc_func() {
        f();
        C::f();
        A::f();
    }
};

class D : public C 
{
public:
    sc_signal<bool> dummy{"dummy"};

    SC_HAS_PROCESS(D);
    D(const sc_module_name& name) : C(name) {
        SC_METHOD(proc_func); sensitive << dummy;
    }

    void f() {
        int m = 3;
    }

    void proc_func() {
        f();
        D::f();
        C::f();
        A::f();
    }
};
// ...
