The DAQ software for ATLAS Inner Pixel Tracker system testing for HL-LHC

The ATLAS experiment is preparing for the High-Luminosity LHC era, by replacing the current innermost detector with an advanced all-silicon tracker (pixels and strips) to withstand radiation damage and increased particle activity. Pixel module quality control tests span various production stages which necessitates a robust data acquisition software capable of handling high data rates for fast readout and performing calibrations at MHz frequencies on several front-ends simultaneously. Yet Another Rapid Readout software, adaptable to diverse hardware platforms including ATLAS Phase-II readout board, facilitates these testing scenarios. This contribution highlights YARR's key features and developments towards benchmarking the performance of the ATLAS inner tracker pixel modules using the official ATLAS Phase-II readout system.
