What is EMIR?
EMIR (Electromigration and IR Drop) is a critical challenge in modern VLSI design. Electromigration is the gradual displacement of metal atoms in a semiconductor, which can cause interconnects to fail. IR Drop is the voltage drop in the power delivery network, which can lead to timing violations and reduced performance. These tools provide an intuitive, visual way to understand and analyze these complex phenomena.
Interactive Analysis Tools
PDN SPR Visualizer
Analyze shortest path resistance in a power grid. Place ports and sinks, and watch in real-time as the tool calculates and visualizes the most efficient current paths, avoiding obstacles and highlighting potential high-resistance areas.
Launch Tool →Static IR Drop Visualizer
Visualize voltage distribution and IR drop across a power delivery network. Select current sources, adjust current levels, and watch animated current flow while analyzing voltage drops and power dissipation in real-time.
Launch Tool →Why This Approach Works
Visual, interactive learning bridges the gap between complex theory and practical application, making difficult concepts intuitive and memorable.
