Worked on the SegmentLinking/cmssw repository to enhance simulation parameter control by introducing configurable mixing options in the Mixing.py module. Focused on configuration management and simulation, the work added new parameters for bunch spacing and flat pile-up distribution, allowing users to select between BS and Flat options for more precise scenario setup. Updated the defineMixing logic in Python to parse and apply these parameters, streamlining the process of tuning and validating CMSSW simulations. This feature reduced manual configuration steps, improved reproducibility, and aligned with project maintainability goals, while no major bugs were addressed during the period as efforts centered on extensibility.
