What are Electromigration and IR Drop in silicon?
Electromigration (EM) is the physical displacement of metal atoms in conductors due to high current densities, leading to open circuits. IR Drop is the voltage drop across the power network due to wire resistance (R) and current (I), which slows down gate operations.
Introduction to Electromigration (EM) and IR Drop Analysis
Understanding the details of Electromigration (EM) and IR Drop Analysis is essential for front-end verification, DFT testing, or backend timing closure in modern sub-micron silicon processes.
This daily knowledge byte offers concise definitions, architectural outlines, and practical design solutions to support your engineering career.
