Example (Counter)

In this example a C++ class is defined using the the SC_MODULE macro.

   sc_in  < bool       > clk, enable, reset;
   sc_out < sc_int<10> > sum;

   void m() // Behaviour 
      if (reset) sum = 0;
      else if (enable) sum = sum.read()+1; // Use .read() since sc_out makes a signal.

   SC_CTOR(mycounter) // constructor
     { SC_METHOD(m);
       sensitive << clk.pos();

Modules inherit various attributes appropriate for an hierarchic hardware design including an instance name field and a channel binding capability.
