  We discuss top-quark physics at the ILC with a focus on the full off-shell
processes for $t\bar{t}$ and $t\bar{t}H$ production, including top-quark decays
and also leptonic $W$ decays. A special focus is on the matching of the
resummed vNRQCD threshold calculation and the fixed-order NLO QCD continuum
calculation, where we present an update on the validation of the matching. All
of the calculations have been performed in the \wz event generator framework.
