The GLAST Large Area Telescope (LAT) is a project for a high-energy gamma-ray observatory. The LAT tracker consists of an array of tower modules, composed of planes of silicon-strip detectors (SSDs) interleaved with converter sheets. The photon detection is based on the pair conversion principle and silicon-strip detectors are used to precisely track the electron and positron produced by the initial gamma-ray. The tracker digital signal read-out has been reproduced by means of a full simulation code describing all the physical process that take place in a SSD. The simulation has been applied to a trigger timing study and the LAT tracker hit capture efficiency has been evaluated. The results obtained will be shown.
