This example builds on the previous randomization examples,but adds a new feature: it uses a seed file to control the randomization seeds.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 structures  test.cc     A test that uses the introspection interface to              randomize the data objects  Makefile    Targets for sun-gnu, hppa-native and linuxA 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 LinuxThis simulation must be run twice.  After first run completesthen run the simulation again.%%Categories            notebook examples introspection randomization%%Cmdln         osci    %%REGSRC/runme %%REGSRC/test.cc "%%TBCMDLNARGS"%%Cmdln         schdl   %%REGSRC/runme %%REGSRC/test.cc "%%TBCMDLNARGS"%%Cmdln         ncsc    %%REGSRC/runme %%REGSRC/test_reg.cc "%%TBCMDLNARGS"%%TBARGS        ncsc    --stop hdl_elab --sconly sctop%%LinePrefix    all%%CheckTest     all     %%REGSRC/checktest.sh origrun.log %%TBLOG %%REGSRC/tb_log%%RealClean             %%REGBLD/seedfile.txt %%REGBLD/initval %%REGBLD/logfile.diff
