  We report the study of top-quark reconstruction in $e^+e^- \to t\bar{t}$
events at a 500 GeV linear collider using the LCD Fast Simulator. The final
states of 6 jets as well as 4 jets and lepton are used. In order to reconstruct
the jets, the performance of charged and neutral cluster separation are
studied. We compare top-quark reconstruction for the LCD Small and LCD Large
detectors, including the effect of varying the calorimeter granularity.
