# Overview

Qualcomm PDN Checker is a web-based tool for analyzing Power Delivery Network (PDN) performance on PCBs. The tool simulates and validates PDN impedance, voltage drop, and DCR specifications for processors and associated power management ICs.

## Key features

- Analyzes PDN impedance response across frequency ranges
- Calculates voltage drop and validates against specifications
- Measures DC resistance (DCR) between VRMs and loads
- Supports multiple chipsets and power rail configurations
- Provides access to intermediate simulation files while eligible jobs are still running
- Generates comprehensive PDF reports with simulation results
