The program includes the C++ iostream header, main TLM 2.0 header and the header of the two modules which will be used:

#include <iostream>

#include "tlm.h"
#include "Or1ksimSC.h"
#include "LoggerSC.h"
	  

The two iostream entities used are brought into the local namespace.

using std::cerr;
using std::endl;
