This wiki describes the simulation work focused on single-particle samples (with and without pileup) and a work on validation of the geometry. The single particle samples created at ANL are discussed here https://twiki.cern.ch/twiki/bin/viewauth/Atlas/UpgradeSimulationInnerTracker The ongoing discussion of how to do full simulations can be found in ATLPHYSVAL-385.

Here are a few results obtained using the single-particle samples for the Extended Barrel 4 geometry. They are based on 1 GeV single particle sample created at ANL https://twiki.cern.ch/twiki/bin/viewauth/Atlas/UpgradeSimulationInnerTracker#EVNT_Single_particle_samples
