We report results of simulation to evaluate the ability of the eclipse mapping method to reproduce the spatial distribution of flickering in cataclysmic variables stars.

Flickering is a fast intrinsic brightness scintilation occurring on time scales from seconds to minutes with amplitudes of 0.01 - 1 mag. Flickering is observed in all sources believed to be powered by accretion is considered a fundamental signature of accretion. Nevertheless, it is one of the least undestood aspects of the accretion process.
