Silicon pixel detectors are at the core of the current and planned upgrade of the ATLAS
experiment at the LHC. Given their close proximity to the interaction point, these detectors will
be exposed to an unprecedented amount of radiation over their lifetime. The current pixel detector
will receive damage from non-ionizing radiation in excess of 1015 1 MeV neq cm2, while the
pixel detector designed for the high-luminosity LHC must cope with an order of magnitude larger
fluence. This paper presents a digitization model incorporating effects of radiation damage to the
pixel sensors. The model is described in detail and predictions for the charge collection efficiency
and Lorentz angle are compared with collision data collected between 2015 and 2017 ( 1015
1 MeV neq cm2).
