Sensitivity Analysis of IR-Drop in Power Grids to Resistance and Geometric Variability

As integrated circuit scaling approaches sub-2nm technology nodes, power delivery networks (PDNs) become increasingly sensitive to both process-induced and geometry-dependent resistance variability. This internship project focuses on evaluating the impact of such variations on IR-drop in power grids using an in-house circuit-level model. The study systematically analyzes how fluctuations in interconnect resistance—arising from manufacturing variations and geometric design parameters—affect voltage distribution across the PDN. By quantifying the sensitivity of IR-drop to these factors, the work provides critical insights for robust PDN design and variation-aware optimization in advanced technology nodes.

Required knowledge and skills:

• Basic understanding of circuit modeling and power grids
• Interest in process and geometric variability in advanced nodes
• Experience with Python, MATLAB, or SPICE
• Analytical mindset and attention to detail
• Willingness to learn and collaborate in a research environment
