SystemC片上系统设计的源代码： 书籍介绍： SystemC是被实践证明的优秀的系统设计描述语言

This example shows how you can create hierarchical
constraints.  A constraint class is created to specify an
initial set of constraints.  A derived constraint class is
then generated, which inherits all of the base constraints
and adds a few more.

This example also shows how keep_only()/keep_out() methods
can be used in conjunction with constraints.

NOTE: keep_only()/keep_out() methods can only be used on
objects that are not involved with complex constraints.  In
this case, the msg variable is independent of all of the
other variables in the packet, so we can use simple
constraints on it. This makes constraint solving much faster
for this variable.

The following source files are part of this example:

  test.cc       A test that contains a derived constraint definition
                and a test that uses the constraint
  packet.h      Definition of a user-defined type with three
                unsigned fields and one array field
  packet_ext.h  Extensions for the user-defined data type
  packet_constraint.h  Base constraint for the packet type
  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
