What is Static IR Drop Analysis?
Static IR Drop analysis examines the voltage drop across a Power Delivery Network (PDN) when a steady current is applied. This helps identify areas of high resistance and potential power delivery issues in circuit design.
How to Use This Tool:
- Auto-Generated Network: The tool automatically generates a 10x10 grid with 1 domain and 7 instances
