Power Integrity Analyzer

Validate the design decisions throughout the design process including the selection board layer stack-up, placing decoupling capacitors on the board, and routing power/ground nets.

Power Integrity Analyzer : A tool designed to evaluate and ensure the stability and efficiency of power distribution within electronic systems. In addition, when viewing each component in the analyzer (see the image below), the pin numbers for each component are also visible, aiding in detailed analysis and troubleshooting.
PCB PDN Analysis : A process used to evaluate the performance and integrity of the power delivery system within a circuit, ensuring that sufficient power is supplied to all components while minimizing noise and voltage fluctuations.
PCB IR-Drop Analysis: A process to evaluate voltage drops in a PCB’s power distribution network, ensuring all components receive adequate power.
- View Type
  - Voltage(V): Displays the actual voltage levels at different points on the PCB, highlighting areas with significant voltage drops.
  - Current Density(mA/mm^2): Shows the distribution of electrical current across the PCB, indicating where high currents may cause voltage drops due to resistance.
  - Heat Density(mW/mm^2): Represents the distribution of heat generated by current flow, which can affect voltage drop and overall thermal performance.
  - Voltage Drop(mV): Directly visualizes the voltage drop across different parts of the PCB, highlighting regions where voltage levels are lower than expected due to resistance.
