Grid Check Analysis in VLSI
🔸 Why Do We Need Grid Check Analysis? Before running any IR drop analysis, one fundamental question must be answered: 👉 Is the power grid itself robust enough? If the grid is weak: IR drop analysis will fail anyway Debug becomes harder and time-consuming 💡 Key Insight Grid check is a pre-check for PDN health. It ensures: Uniform power delivery No weak connectivity No broken or…
