We assume that universe is dominated by non-relativistic matter and tachyon
field and reconstruct the potential of tachyon field directly from the
effective equation of state (EOS) of dark energy. We apply the method to four
known parametrization of equation of state and discuss the general features of
the resulting potentials.
