This example shows how to overload the operation of the
next() method inside a constraint, in order to have
functions called before and/or after randomization.
Overloading the next() method is a powerful way of
customizing randomization.

NOTE: You can also overload the next() method in an
extended data object.

The following source files arg part of this example:

  constraint.h a user defined constraint which constrains
               a data object with respect to the current
               value of an sc_signal<> object.
  test.h       a SystemC module definition with a signal to
               which the constraint is applied 
  test.cc      definition of the SystemC sc_main routine
               where the SystemC module is instantiated and
               simulation begun.
  Makefile     Targets for sun-gnu, hppa-native and linux

A makefile for use with SystemC is provided with targets for
three different platforms:

  make sun-gnu        # Gnu C++ compiler on Sun
  make hppa-native    # HP C++ compiler on HP
  make linux          # Gnu C++ compiler on Linux
