During June 2025, Dhananjay Nadkarni focused on parameter tuning for performance and power estimation in the tathagatasrimani/codesign repository. He updated the tech_params.yaml configuration file, refining initial values for area, dynamic power, latency, and leakage power to better align with revised hardware models. Leveraging his skills in hardware design and parameter tuning, Dhananjay ensured that these changes improved the accuracy and reproducibility of performance and power estimation workflows. The work was anchored to a single, traceable commit, supporting reproducible results and transparent parameter management. YAML was used as the primary language for configuration and workflow integration.
