Hi Yu,
Those are fundamentally the same scripts, except for the
restrictions of the random event generating programs.
@DesignSearch uses RSFgen by Doug Ward (written
almost 20 years ago). The @stim_analyze script works
with make_random_timing.py.
The real question is which such program is capable of
generating events suitable to your needs.
make_random_timing.py is capable of handing far more
advanced designs (which does not mean it can handle
any design - it cannot).
