This is a very simple example to show how a user canrandomize data. This example builds on examples 1-3, whichshowed how to create user-defined data types.This example uses the static scv_random::set_global_seed()method to force the initial seed value. This method ensuresthat two simulation runs will produce the same results, aslong as the number of random objects and order of randomobject creation is unchanged. There are more sophisticatedmethods for ensuring reproducibility, but we use thesimplest form for this example.The following source files are part of this example:  data.h      The definition of a user-defined structure  data_ext.h  Extensions for the user-defined data types.  test.cc     A test that uses the introspection interface to              randomize the data objects  Makefile    Targets for sun-gnu, hppa-native and linuxIn order for a structure to have introspection capability, auser must define a scv_extensions<> template specializationfor the particular struct.A makefile for use with SystemC is provided with targets forthree 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%%CATEGORIES            notebook examples introspection randomization%%TBARGS        ncsc    --stop hdl_elab --sconly sctop%%LinePrefix    all%%Files         none    %%REGSRC/test.cc %%REGSRC/test_reg.cc%%Files         osci    %%REGSRC/test.cc%%Files         schdl   %%REGSRC/test.cc%%Files         ncsc    %%REGSRC/test_reg.cc%%CheckTest     all     %%REGSRC/checktest.sh %%TBLOG %%REGSRC/tb_log.au%%REALCLEAN             %%REGBLD/logfile.diff
